Abstract
In explaining Iron Age archeology, the study of metal artifacts is of particular importance because of the hidden technical values. The study of metalworking methods enhances our understanding of the industrial centers of metallurgy, stylistics, and available mines. The purpose of this study is to identify the methods of construction and elemental analysis of “ornaments” discovered from “Iron Age” sites in northwestern Iran, using metallographic experiments and an SEM-EDS elemental analysis device. In the Iron Age, the making of metal objects, especially those with many ornaments, flourished. Therefore, knowing the manufacturing methods and the type of alloy used in them is one of the essentials of this research. This research responds to the question, what methods used to make the discovered ornaments from the Iron Age sites in the northwest? Or what were the most used elements in the construction of these objects? In these areas, the current research hypothesis is that most of the “ornaments” made by hot hammering and casting methods and have a large amount of tin in their structure, which uses for greater strength and flexibility of copper and tin (bronze) alloys. In this study, several samples of ornaments discovered from Iron Age sites in northwestern Iran, which were geographically very close to each other, were tested by metallography and elemental analysis. In this experiment, using a scanning electron microscope equipped with an SEM-EDS element analyzer, making these metal objects and their constituent elements were determined. This study shows that the main methods of making these metal objects have been hot hammering, but those objects that had a large volume made using the casting method. Also, the most used element to increase the strength and flexibility of objects is the element of tin.

Introduction
In the Iron Age areas of the northwest, metalworking was done at an advanced level. The expansion of the tradition of metalworking in the northwest can be seen in other Iron Age areas of Iran. (Talaei, 2001:77-83) One of the reasons for the development of metalworking in the Iron Age areas of northwestern Iran has been the abundance of copper and iron ore mines in this region. During the excavations of the Hasanlu area in the south of Lake Urmia, founded a large number of iron and bronze objects. The large volume of metal objects discovered in the Hasanlu area indicates the prevalence of metalwork in this region of the Iranian plateau. (Pigott, 1989: 67-79) According to the studies, the residents of Hasanlu have supplied their required copper ore and iron ore from the mines that probably existed around this area. The development of metalworking art in this region, in addition to the existence of metal mines and fuel reserves, has been the development of furnaces and metal smelting molds, which in some Iron Age sites such as Hasanlu, obtained a large number of these metal smelting molds. The main reasons for the development of technology and style of metal products in northwestern Iran in the Iron Age could have been powerful governments such as Urartians and Manas. (Aliun and Sadraei, 2011) They were skilled metalworkers in the vicinity of Iron Age sites. One of the signs of this effect is discovering a bronze bracelet discovered in the Toul Talesh cemetery in northern Iran, which shows the expansion of Urartian territory in this region. There is a Urartian cuneiform inscription on it. This inscription shows that Argishti II, King of Urartu, gave this bracelet to Khaledi God. This person could have been a prince or a military person. (Tahmasebi and Masoudi Nia, 2015) The main issue of this research is to know the construction methods and the constituent elements of the jewelry discovered from the northwestern region of Iran. In the Iron Age, especially the Seldouz valley, these sites are primarily located in the Seldoz Valley and are geographically very close to each other, which can help understand the methods of construction and elemental analysis of the metal samples tested. The present research has been done by analytical-experimental method and based on scientific and laboratory studies. The purpose of this study is to identify the methods of construction and elemental analysis of “ornaments” discovered from “Iron Age” sites in northwestern Iran, using metallographic experiments and an SEM-EDS elemental analysis device. This research responds to the question, what methods used to make the discovered ornaments from the Iron Age sites in the northwest? Or what were the most used elements in the construction of these objects? In these areas, the current research hypothesis is that most of the “ornaments” made by hot hammering and casting methods and have a large amount of tin in their structure, which uses for greater strength and flexibility of copper and tin (bronze) alloys.

Materials and Methods 
In this research, the first eight metal samples from different Iron Age sites in northwestern Iran were collected through the reservoir of the National Museum of Tehran and sampled in the same place, and then sent to the Materials and Metallurgy Laboratory of the Sharif University of Technology for metallographic testing.

Discussion
Laboratory analysis and elemental analysis of metal samples using the SEM-EDS method show that a small amount of arsenic was founded in the alloy composition of the samples Because most copper metal ores before extraction and smelting contain amounts of arsenic. Therefore, there is a possibility of the unintentional existence of arsenic in the composition of these metals. Another element that a large percentage obtained in the composition of these metal samples is tin. Metallographic images of the ML-98-7 and ML-98-8 specimens show that these two specimens have a branched or dendritic structure in their body and are made by casting. Also, tiny cracks on the metallographic images of ML-98-2-ML-98-3 and ML-98-6 samples formed due to stress and fatigue caused by continuous hammering work on these metal works. The dark spots seen in most of these microscopic images indicate oxygen, carbon, and a lack of copper and tin, which have caused corrosion and sulfidation of these metal objects.

Conclusion
The results from the images obtained by scanning electron microscopy equipped with an SEM-EDS device found that the metal samples have a relatively large amount of tin. A small percentage of arsenic found in the metal samples tested. Considering the amount of arsenic in these samples can be concluded that metalworkers of this period may not have noticed the harms of using arsenic at that time and therefore used this element to improve the properties of bronze alloy. Ancient metalworkers used tin, arsenic, and antimony elements in the composition of bronze alloys to increase the hardness of the work. The items in the category of jewelry need to pay more to get the right shape. Another possibility is the unintentional presence of arsenic. The presence of large amounts of tin in these samples indicates that arsenic may have been naturally present in copper ores and Ancient metalworkers used tin to lower the melting point of copper and increase its strength and flexibility. Microscopic studies of bronze objects show that many copper sulfide compounds are present in metal samples. The presence of copper sulfide inclusions dispersed on the surface of the metal matrix and stretched in the longitudinal direction of the microstructure of ancient copper alloys may indicate the use of oxide ores along with some copper sulfide ores for extraction. Most of the ornaments found in the northwestern Iron Age sites, such as bracelets and collars, were made by hot hammering, subsequent hammering or forging, and objects with larger volumes and decorations molded by casting. In general, the objects discovered from the Iron Age sites in the northwest, especially the Hassanlou site, are more complex in terms of technique and construction style than the Iron Age sites in other parts of Iran, where existed local and indigenous governments. This issue has been due to the proximity of northwestern Iran to powerful governments such as Urartu and Manna.

Abstract
The beginning of the Iron Age on the Caspian Sea coast and the adjacent areas on the Iranian plateau and the neighboring lands was accompanied by extensive social, political and cultural changes that led to the collapse of urban centers and exchange economics, the formation of scattered and rural communities, which were often followed by livestock or nomadic economics. Changes in the social structures in the Bronze Age and the beginning of the Iron Age, for whatever reason, caused extensive changes in the cultural material of the Iranian plateau and the Caspian Sea and formed settlement patterns from which only the associated cemeteries have often been identified and excavated. However, the residential structures, the spatial organization of the settlements and their relationship with the cemeteries are not well known. Excavation on the Parija Tepe, 3 km from Qaem-Shahr-Kiakola road on the low shores of the Caspian Sea, resulted in the identification of two stages of settlement from the Iron Age and the Early Islamic period. The Iron Age finds include pottery, metal objects, stones, bones, animal remains, and the remnants of architectural structures. According to the obtained evidence, the largest volume of cultural layers in the Parija Tepe is related to the Iron Age. The present study indicates that the Parija Tepe has an important place not only in better understanding of the pottery traditions of the Iron Age in the Caspian lowlands, but also in identifying mud-brick architecture and the pattern of sedentary life in this region. Further archaeological excavations of the site will undoubtedly give a clearer perspective on the social organization and settlement patterns of the Iron Age in the coastal areas of northern Iran.

Introduction
One of the characteristic features of Iron Age sites of Mazandaran is the lack of settlement sites with visible architecture, the abundance of cemeteries, special funeral rituals, as well as a distinguished pottery tradition. During the Iron Age, the majority of dead people were buried in simple pit graves, Mud-brick lined graves or Pithos burials. The dead were often buried in a curved or flexed position, and in limited cases in supine or stretched position. A variety of burial-goods often placed next to the dead, a tradition which was also common in the preceding Bronze Age and that became more prominent during the Iron Age. In addition to the large number of pottery vessels, a good variety of tools such as swords, daggers, knives, spears, and other objects made of bronze and sometimes iron, as well as jewelry such as rings, bracelets, necklaces, plaques, and seals of bronze, silver, iron, bone, faience, stone, and rarely gold have been reported alongside the skeletons. While results of archaeological research in the Iron Age sites of Mazandaran suggests the influence of local Bronze Age cultures on the later Iron Age communities but, it appears from the available evidence that the Iron Age settlements are smaller albeit larger in number compared to the Bronze Age sites. 
The present article introduces the results of excavation in Perija Tepe in the Caspian Sea shores. Results of excavations suggests the important role of Parija Tepe not only for a better understanding of the Iron Age pottery traditions in the coastal lands of the Caspian Sea, but also for the identification of permanent settlements through examination of mud-brick architecture and the pattern of sedentary life in this region. Archaeological excavation at Parija Tepe can provide a clearer perspective of the social organization and settlement patterns of the Iron Age in the coastal areas of northern Iran.

Discussion
Parija Tepe is located in the central part of Mazandaran plain, some 3 km to the northwest of Ghaemshahr, next to the road from Ghaemshahr to Kiakola (Simorgh) and among the paddy fields of Kolagar village. Recent excavation at Parija Tepe has led to the identification of two phases of settlement belonging to the Iron Age and the early Islamic period. The main settlement phase and the majority of cultural depositions at Parija Tepe dates back to the Iron Age which is divided into Iron Age II and III. 
Typologically, most pottery forms of Prija appears to reflect the characteristics of Iron Age II. In addition to the pottery vessels, significant cultural materials such as a tanged bronze spearhead and a stone stamp seal were also excavated. One of the most remarkable findings of this excavation is the discovery of remains of mud-brick architecture that possibly shows a sedentary lifestyle rather than a nomadic way of life. Bio-archaeological studies on the faunal remains of the site demonstrates that all animal bone remains belong to mammals, and no fish, birds, rodents or reptiles have been identified. Throughout the occupational period, sheep, goats and cattle are the dominant species, followed by boars. Very rare remains of red deer have also been seen. Thus, it seems that the subsistence economy of the inhabitants of Prija has been diverse and based on livestock activities, agriculture and hunting patterns.

Conclusion
The cultural material discovered from excavation of Parija Tepe represents the cultural traditions of the Iron Age and indicates cultural links between this area and other Iron Age sites in the northeastern and north-central regions of Iran. Although some rich cultural materials such as a tanged bronze spearhead and some pottery forms have their roots in the Bronze Age cultures of the Northeast and the Gorgan Plain, the production of these type objects has continued throughout the Iron Age and striking analogies could be seen in large areas of Gilan and Mazandaran and the southern slopes of Alborz. It seems that the main volume of pottery and other cultural materials retrieved from Parija excavation indicates to Iron Age II and II period occupation with the material cultures resembling those from contemporary cultures in the north and northeast of Iran. The results of preliminary studies of Parija Tepe indicates that this area, like many of its contemporaries in Mazandaran, is formed near the river and in a flat and fertile land, and in terms of architecture, similar to other Iron Age sites in Mazandaran, has wooden and mud-brick architecture. Therefore, Parija, along with other Iron Age sites of the region, indicates to the uniformity of the Iron Age material culture in the lowlands of Madandaran, which, while similar to the Iron Age cultures of the southern slopes of Alborz, has particular local features.

Abstract
Varamin-Pishva plain is one of the most important cultural areas of the southeastern part of Tehran plateau in different historical periods. Taghabad Tepe with two western and eastern elevations and consisting of different rich layers of Iron and Bronze Age is located in this plain. This site has been studied and archeological research in 1397. In this study, it was found that this area has different deposits from the Iron Age one and two in the upper layers and traces of late bronze in the lower layers along the horizon with the common western traditions on the plateau. The aim of this study was to analyze the mentioned findings and compare it with the findings of other areas of Varamin plain and other neighboring areas. The questions of this research are as follows: based on the archaeological findings of the cultural developments of Taghiabad Tepe, what kind of cultural traditions dose the Iron Age have? What is the influence of regional and trans-regional cultures of the common Iron Age cultures of Varamin plain due to the Taghabad findings in the type of pottery and architecture? Accordingly, the Iron Age 1and2 of Varamin plain and especially Taghiabad Tepe to some extent shows the regional actions in Varamin plain and the proximity and convergence of the trans-cultural region with neighboring areas.

Introduction
Varamin-Pishva plain, having a suitable geographical position in the slopes of Alborz mountain range and Damavand peak and having a suitable height, has provided suitable ecological conditions for the presence of human communities for a long time. This plain is one of the areas prone to the formation of Iton Age settlements in the north-central part of Iranian plateau. During the archaeological study of this area in 1391-1392 AH. Has identified 27 sites belonging to the Iron Age (Figure1), as a result of studding the findings of this study, only a few sites have been introduced and identified. In this research to analyze and study the pattern of establishment and distribution of sites as well as cultural stages of the Iron Age of Varamin plain by analyzing cultural findings identified from  Iron Age sites based on archaeological studies and cultural traditions of this plain by case study, especially pottery, and the architecture identified from workshop A in the eastern ridge of Taghiabad area as well as the surface findings obtained, classified and then the location of this area in Varamin-Pishva plain next to the Iron Age settlements in the center of Iranian plateau, in a general view, reviewed, evaluation and analysis are included. In this review, understanding the Iron Age communities, especially the Varamin plain will be accompanied by re-reading various theories.

Research Method
The present research is structurally one of the basic researches with a comparative-analytical approach, the method of finding is to exploit the findings of an archaeological excavation chapter based on historical analysis of the findings of Taghibad Tepe. According to the research topic and the variables studied in it, the method of collecting information in the field and data collection tool in this research will be based on archaeological excavations and related reports and articles. 

Taghiabad Tepe
Taghiabad area is located in Javadabad rural district and between Taghiabad villages, Khajoo Qaleh and Ajorbast counties in the agricultural lands of Taghiabad village in Varamin city. This site was considered in the framework of joint cooperation between the Institute and the University of Berlin in 1397 AH to collect samples of ancient climate studies from ancient deposits and according to the surface findings of the Iron Age and Bronze Age and according to the situation. The demolition of the site was speculated. The site is located in the west and near the Ali Kharat River. Cultural and settelement findings of this research have been identified in Taghiabad Tepe from workshop A in the ridge No1 of Taghiabad Tepe (eastern ridge) and in the northern side of this Tepe in the area that was excavated with an area of 1/5×2 meters (Figure5). From this Tepe, seven settlement phases with two historical periods from Locus have been identified, which include artifacts from the Iron Age 2 and 1 to the late Bronze Age. The cultural materials of this Tepe are all kind of pottery covered with red, cream and brown mud, gray, architecture (walls and thermal structures) plaster, pounded floor, stone tools such as pounding stone, abrasive stone , burnt plant seeds (in terms of appearance similar to wheat or barley) it has formed a bony specimen, goat horn and clay tokens, etc., which will be described below

Conclusion
The results of the study of Varamin plain settlements from its archaeological of Iron Age communities, based on Taghiabad Tepe excavation, this area and site as an important area and indicators in the study of Iron Age cultures and chronology of the Iranian plateau. One of the most important topics in the archeology of the Iranian plateau is how the tradition from the Bronze Age to the Iron Age and its sequence, one of the important features of Taghiabad Tepe is the presence of communities from the Iron Age and their cultural connection with the Bronze Age which is of great importance in the studies of the tradition from the Bronze Age to Iron (Age)., an area where settlement began in the Iron Age and continued until the Bronze Age . Accordingly, in this study, questions were raised that can be evaluated in this way. The first question was asked about archaeological findings, cultural developments of Taghiabad Tepe and how the cultural traditions of the Iron Age. The urban complex and evolution of later cultures with cultural establishment has been one of the actions of the neighboring horizon in the type of architecture and pottery, especially Gholi Darvish. The second question was asked about the interactions and influence of regional and supra-regional cultures of the common cultures of the Iron Age of Varamin plain due to Taghiabad findings in the type of pottery and architecture, which according to the surface findings of 27 sites recorded in studies, archaeological as well as various excavations in Sofalin Tepe, Chalnasian and other areas, this plain to some extent shows intra-regional activities with the center of Taghiabad Tepe, with cultural trans-regional affinity and convergence with adjacent areas in the southern and northern parts of the central plateau of Iran. Therefore, it can be considered that the Iron Age sites of Varamin-Pishva plain, especially Taghiabad Tepe, are the product of an advanced society with a cultural establishment of adjacent horizon actions in the type of “architecture” and “pottery”. Based on the types of pottery and the type of architecture the cultural sequence of Taghiabad Tepe can be introduced with 7 phases of establishment in two historical monuments. Finally, it can be said that based on the relative and comparative dating of Taghiabad Tepe, it can be dated to the late bronze period of the transition period and the Iron Age of one and two.

Abstract
Cylinder seals usually were used on clay objects, especially tablets, as a symbol of individual’s identity and administrative centers of the ancient East. While, rare potteries sealed by cylinder seal are a new case for archaeologists. Based on the small number of sealed pottery fragments found, archaeologists are dealing with several main questions: Why cylinder seals used on pot-tery? What is the usage of sealed pottery? And whether it is possible to provide an exact chro-nology for these potteries? A sealed pottery fragment from the site of Qal’eh Asrār in South Khorāsān is an example which is also our subject matter in this present study. The area of Qal’eh Asrār is located 1800 meters southeast of Barandood village and 800 meters northwest of Zarbarandood village of Ghohestān section of Darmiān city. This area is currently located on top of a natural hill at a height of about 200 meters above ground level. Analysis of potteries found on the surface of site shows that the occupation of it belongs to Late Iron Age and Achaemenid period, although there are also small numbers of pottery belonging to the late Is-lamic centuries. In this paper we try to study a fragment of a sealed pottery found from surface of site. Firstly, we deal with the issue of sealed pottery with regard to the context and the prob-lems and challenges of its study, then we try to analyze sample pottery of the Qal’eh Asrār in terms of typology, style and its legend. This study shows that the sealed pottery of Qal’eh Asrār is locally produced and its legend is a local style with the common motifs of first half of the first millennium BC. As this site is probably a garrison, this container could be used for bearing commodities to the construction.

Introduction
In ancient near East, the stamp and cylinder seals have been used on diverse clay objects such as bullae and tablets to sealed administrative documents, but use of seals on pottery is rare. Since 3rd millennium B.C Fragments of sealed pottery have been found in sites from north Iraq and Syria (Collon, 1987: 13; Oates, 2001), Levant (Amiet, 1975: 425-426), west and south western of Iran (Caldwell, 1976), Shahr-e Sukhta in south east of Iran (Baghestani, 1997: 34- 43; Hakemi & Sajjadi, 1989: 145) and central Asia (Sariandi, 1986; Heibert, 1994a). Several fragments back to the Iron Age I and II were found from Bahrain in Persian Gulf (Olijdam, 2008) and Central Plateau of Iran in Tepe Sialk (Malekshahmirzadi 1381: 25) and Gholi Dar-vish in Qom (Sarlak 1386: 193- 194). Most of these sealed potteries are small fragments that have been found mainly as single fragment on the surface of sites. A small number, such as the Gonur Depe fragment in Turkmenistan (Sariandi, 1986: fig.123) or the Tell Brak in Syria (Oates, 1985: 257), have been found from archaeological excavation. 
In archaeological survey of Qal’eh Asrār in South Khorasan, Iran, one fragment of sealed pot-tery with a cylinder seal impression was found in archaeological survey. There are several questions raised here. Is it possible to provide an accurate chronology for the sealed pottery of Qal’eh Asrār? Why the pottery sealed, specifically with cylinder seal? Are these sealed pottery have an administrative function and were used as a kind of administrative-economic object or tool? Or here seals just used as decoration? In this paper, which is a descriptive-comparative and analytical approach, firstly we examine the challenges related to chronology and recogniz-ing the function of sealed potteries in archaeological studies, then we focus on study Qal’eh Asrār fragment and its seal impression.

Chronology and Usage of Sealed Pottery
Archaeologists have two different approaches for chronology of sealed potteries. If these frag-ments are found from excavation, they propose site stratigraphy to date it. But, most of the sealed pottery has been found on surface of sites, so dating will be complicated. In fact, archae-ologists use two methods to date sealed potteries, such as Qal’eh Asrār case; they propose the chronology based on typology of pottery or the style and image of seal impression. 
Function of sealed pottery is under debate too; there is no consensus on why sealed potteries are made and how it has been used. In general, the proposed suggestions can be divided into three groups, although, there are many doubts about each of these three views. 
1- The image of seal on pottery was for decoration.
2- The seals are the sign or signature of the potters who identifies the ownership and identity of his handicrafts.
3- Sealed pottery has an administrative function and has been used for storing or moving com-modities.
The style and image of the cylinder seal impression of Qal’eh Asrār sealed pottery
The image of Qal’eh Asrār seal does not show a unified theme and its upper part is broken. In part of the image a human is standing, bending one hand from the elbow and holding a cane, his other hand is not clear, it had stretched body with broad shoulders and arms, the proportion be-tween the upper body and the legs is not observed and the upper body is taller than the legs. It seems he have a dagger in his waist. On both sides of the human image are two birds. On the left side is design of the quadruped (donkey?) and in front of it is a horse, both are upside down. Of course, the horse’s head is broken. Between the two images are a small bird at the top and probably a sitting human at the bottom. The style of Qal’eh Asrār seal is a local style which focusing on the outer lines, not paying attention to the details. 

Conclusion
Studies on sealed potteries in diverse sites, despite different time and cultural periods, shows the following common features can be observed:
1- All fragments of sealed pottery are locally produced.
2- The seals that are used on these potteries also have a local and indigenous style, and this in-dicates the locality of their production.
3- Sealed pottery fragments indicate they should mainly belong to medium and large jars.
 4- In most of fragments seal was mainly used at the area between the neck and body of the ware. 
Given the common features mentioned, it can be argued that these potteries had an administra-tive aspect. However, they used locally which both the pottery type and the seal originate from the local culture of the same region, and there are no examples that show their displacements or dispersion in a wider cultural context.
A comparative study of Qal’eh Asrār sealed pottery shows that this pottery is locally produced and cylinder seal used on it also has local style of the 1st millennium B.C. Due to pottery type and the presence of architectural remains, this area is suggested to be a garrison to protect the road in the late Iron Age - early Achaemenid period, and the style and image of the seal on the pottery also confirms the proposed chronology. 

Abstract
Among the collection of findings from the archeological excavations of the Iron Age cemetery of Lefour, in Savadkuh, there is an engraved a two-humped camel on a bronze belt buckle, skillfully made through molding method. According to the studies of physical anthropology, in terms of morphology of the skulls, it shows that the excavated dead bodies were different from the previous inhabitants, and the grave goods also indicate they were cattle breeders and nomads. The most prominent object found is a bronze belt buckle with the engraving of a western two-humped camel on it; this animal is definitely not native to the southern region of the Caspian Sea, and may belong to the plains of Central Asia; the southernmost habitat of this type of camel is in the north of Gorgan plain and in the south of Turkmenistan. In the Achaemenid period, two-humped camel is also shown with groups of gift givers who came from Central Asia and the east of the Caspian Sea. In the memorial stone carvings of Shalmaneser III, the King of Assyrians, there are also people carrying two-humped camels, along with the inscriptions seem to be belonged to a far distant country in the east. The most important questions in this study are: Were the human remains found in this cemetery are native or migrated from other areas? Whether the obtained grave inputs were made on site or imported, and to what extent were they influenced by the artistic and industrial techniques from near or far areas? And is it possible to reconstruct the migration route of these groups in the fertile and foothill areas of Mazandaran by studying the findings of this research? In this article, in addition to comparing the form and nature of the bronze belt buckle with other findings of Lefour Cemetery, the authors analyze and interpret it regarding historical documents and sources to provide more accurate answer to the questions. The result of the research reveals that this object was produced in another place and entered the region through immigrants.

Introduction
The study and interpretation of the cultural characteristics of past societies and the study of the evolution of cultures based on the cultural relics left by these societies constitute the main framework of archaeological studies, the most important evidence in this regard is material and tangible effects. It is complex and difficult to know more accurately the cultural relics of past societies by relying on purely material evidence. The deep connection of religious beliefs with social customs and economic activities is one of the characteristics of past cultures. Therefore, one of the most important sources for understanding the religions, culture and functions of its predecessors is the study of ancient formulations and cultural materials. In this method, researchers usually consider one or more formative features such as objects placed inside the grave, adaptation of the grave or the general plan and location of the cemetery, and then, based on that class or social status of the buried people, adapt to the form, and compare the nature of objects. Despite the importance of accurate and scientific analysis of objects and graves from the Iron Age to explain religious beliefs, no independent research has been done so far. 
Research Question: The most important question that arise as a result of the two chapters of excavation of Lefour Cemetery is that according to anthropological studies  and comparison of ancient date, the graves of the deceased were relatives who migrated to this place from other areas and due to the similarity of form and was the nature of the particular object in question imported? And to what extent has it been industrial practices from near and far?
Research Method: In archaeological research, in addition to printing and disseminating data from field activities of an area, it is possible to analyze and compare the form and nature of an object with the data of regional and supra-regional sites to analyze the origin of a culture. In this article, focusing on the role of the bipedal camel on the bronze belt discovered from data from the Iron Age, Lefour and the similarity of this or that with the role of the western camel of the Persepolis donors, as well as the memorial stone of Shalmanser III it reinforces the hypothesis that it was intended to be imported and that its origin was in east and north of the Gorgan and Turkmenistan plains. 

Belt buckle with the Motiv of Balkhi Camel
The most prominent object of this burial was a unique Bronze belt buckle with the image of a Balkhi bipedal camel, and it is made by casting and embossing method and is reminiscent of desert and arid regions of the east of the Caspian Sea and the steppes of Central Asia

Conclusion
The plain and mountainous regions of the south of the Caspian Sea due to their suitable biological and climatic conditions are very important in studying the settlements of the Bronze and Iron Ages, but unfortunately no independent and complete research has been done on the origin and end of this period. It is done on a case-by-case basis and separately from each other in terms of time and place. Leford Savadkuh Cemetery is no exception. Regarding Leford Cemetery, it should be noted that according to the knowledge of cemeteries and settlements in the center of Mazandaran, it is clear that the cemeteries of nomads in mountainous area, unlike the plains, are often small and limited, and each cemetery probably belonged to a specific group or tribe. The nomads, whose main occupation was herding, spent most of their time in the highlands, migrating animals from one place to another in search of pastures throughout the year and the works obtained also show that in this sense it is economics and small works have on animal husbandry.

Abstract
The Iron Age in the Middle Asia and an important part of it that called Khorasan is a Transitional period between prehistory and historical period. This period always has many ambiguities and questions; Especially in Khorasan, where the lack of archaeological studies is strongly felt. In this area, the Neyshabur Plain has a special position in terms of archeology and is undoubtedly influential in understanding the cultural components of the Iron Age in the region. In the current study, Milad Tape, which is located almost in the middle of Neyshabur Plain, was sampled as a systematic survey. The purpose of this work is to obtain information that can be used to advance the long-term goals of interpreting the Iron Age in Khorasan, especially Neyshabur. In this regard, the most important question is how Iron Age in the perspective of recent studies of Khorasan cultural field. In Milad Tape, whose surface is flat and smooth, sampling of cultural materials has been carried out in the framework of a systematic survey in order to study the Iron Age in a comparative approach with the typology and classification of pottery. Also, by using the settlement pattern of the area and other settlement components of Milad Tape, it is possible to fully examine and read part of the unknown structures of the Iron Age of the Neyshabur Plain and, accordingly, Khorasan. According to the research results, Milad Tape, which has a settlement sequence in the Iron Age, can be interpreted in the framework of the Early to Late Iron Age of the region. Pottery typology studies, also show similarity with the Central Asia Iron Age, which is known as Yaz I to III based on the material cultural of Yaz Depe area. In general, in the comparative approach, Milad Tape samples are closely related to Yaz pottery tradition.

Introduction
Among the archaeology and cultural periods of Khorasan, there is a lack of studies in the second and first millennia BC.  Although the first study of this region that led to the recognition of the Iron Age, dates back to the 1980s (Riccardi, 1980). In recent decades, archaeologists have tried to make the knowledge of this period more complete (Vahdati, 2015, 2018; Basafa, 2021, 2020, 2015, 2016). The most important archaeological investigations consist of Atrak River project in North Khorasan (Dana, 2015 and 2019; Vahdati, 2016), Daregaz Plain (Basafa & Hedayati, 2020), Neyshabur Plain (Basafa, 2017), Roshtkhar Plain (Rezayi, et. al., 2018), Gonabad Plain (Basafa, 2021) and Birjand Plain (Dana, 2014).
From the mentioned researches, it can be understood that neighboring cultures are very important, such as the ancient Dahistan culture in the northeast of the Mazandaran Sea, which can also be seen in the plains of Gorgan and North Khorasan (Lecomte, 2005) and Yaz culture (Kohl, 1984: 193).
In completing the archeological information of Khorasan Iron Age, Neyshabur plain sites are very important because of the location of Neyshabur plain and its environmental potentials (Rezaei & Basafa, 2019). Milad Tape (Fig. 1) is located in this geographical environment, which belongs to the Iron Age. Milad Tape and other sites like Se Tape can show new evidence of local cultures and cultural interactions with Central Asia.
Materials and Methods: This research relies on the material cultures that collected from the systematic survey of site. It’s most important cultural materials are potsherds, were first studied in a statistical approach and then analyzed comparatively in comparison with neighboring cultures.

Data 
In the sampling conducted in Milad Tape, were obtained various stone tools such as blades and chips, metal melting slags, furnace welds and a significant number of potsherds. A total of 1586 pieces of potsherd have been sampled from the surface of the site, and among the three general categories of rim, body and floor, the most abundant pieces belong to the body. From the total samples that can be dated in Iron Age I, the rim has a frequency of 1%, the body 93% and the bottom 6%. In the Iron Age II and III, the rim and the bottom with an abundance of 3% and the body with 93% of the total have the most parts. Among the examples that can be dated in this site, where a comparative approach was used, three periods can be distinguished from the Early to the Late Iron Age. 

Discussion 
Looking at the most important cultural material of Milad Tape, we can say that its pottery components are closely related to Central Asia. In the Early Iron Age, in this site, an important phenomenon is low-quality handmade pottery, which is considered one of the main characteristics of Yaz I. In the middle and Late Iron Age, the previous statements also apply, and its morphology also shows that similarities in terms of construction and form can be seen in Milad Tape pottery in these periods as well. In this context, double-lobe pottery, which is defined as the most important characteristic of Yaz II and III cultures, was produced in a wide range with minor changes in the Neyshabur plain.
In completing the studies, environmental factors are very important, and based on this, Milad Tape is located in the range of 900 to 1200 meters above sea level in terms of height, and in terms of the settlement pattern, it is located in the lowlands of the Neyshabur plain (Fig. 7), which has suitable land for population development. The study of Milad Tape water resources, which undoubtedly played an important role in choosing the location of the sites, shows that there is a direct relationship between the water resources and the location of the site, so that its small distance from the water sources has caused it to grow well in terms of dimensions. Milad is located near Kale-Shure in the center of the plain (Fig. 8) where many waterways and streams flow into it, the most important of which flowed a short distance from the site. This satellite has been able to facilitate access to water resources for agriculture and livelihood. The study of land use (Fig. 9) also shows that Milad is in a good agricultural position and probably suitable water sources have caused agriculture to be carried out by hydroponics in this area. Based on this, the location of the settlement surrounded by suitable pastures has provided the conditions for animal husbandry and livestock breeding for the livelihood of the population of the area. Based on the mentioned materials and in the general view, Milad Tape has created suitable conditions and platform for the use of agriculture in the region. On the other hand, the existence of pastures has provided the grounds for subsistence economy based on animal husbandry. 

Conclusion 
Due to the strategic location of access to water resources and the use of fertile soil, Milad Tape is one of the important sites and settlements in this area, along with other sites, especially Set Tape. By analyzing the cultural materials, a settlement sequence from the Yaz I period and its continuation to Yaz II and III was observed, which shows that it was of special importance in the Neyshabur plain and was efficient in drawing chronological horizons and presenting cultural components along with other sites. The few analyzes of the settlement pattern of Milad Tape also show that suitable water sources were available and the agricultural land was ready. This location selection pattern is also observed in Central Asia. Based on biological patterns, fertile soil, and agricultural use in the effective use of land in the Milad Tape area, it shows that there was a permanent settlement with a livelihood based on agriculture in its settlement area, which may have been three hills. The influence of the cultural characteristics of Central Asia and Yaz culture in Milad Tape, according to the typology of pottery, shows the influence and cultural interactions.

Abstract
The concentration of activities and sites Iron Age excavations carried out in Iran in the quarter-northwest Iran. It covers the west, northwest, north of the center, and the west bank of the Caspian Sea. The important point is that the chronological basis of the Iron Age in Iran is also based on the excavation of several sites in a small part of the northwest and its extension to the whole of Iran. Thus we see the Iron Age archaeological activities at the eastern part of Iran and especially North East is very unknown. Iran has long been the entry point for people without a nomadic component steppes of northeastern North Asia region is the Iranian plateau. According to written sources the oldest nations that have entered the Iranian plateau, known as the Indo-Iranian or Aryan tribes from the steppes of northern Asia to the south and in the land of the Pamir Mountains to Anatolia widely dispersed. Many scholars consider the gradual movement of these tribes to be from the second millennium. A period that is almost synonymous with the Iron Age in the region. But our knowledge of the Iron Age northeastern Iran today virtually all North Khorasan Province and the northern part of Khorasan Razavi province involved is negligible. This paper is based on the latest research picture of the Iron Age northeastern part of the country, with emphasis on the upper basin Atrak be provided. According to the study and identification carried out in this basin, the Iron Age of the upper Atrak basin is part of the Yaz 1 culture.
Keywords: Northeastern Iran, Iron age, Upper Atrak basin, Yaz 1 Culture, Archaic Dehistan, Settlement Patterns.

Introduction
It has been less than a decade that steps have been taken to understand the Iron Age in Northeastern Iran through surface explorations and excavations. Based on this, it seems that some parts of northeastern Iran are in the cultural area of Archaic Dehistan and another part is in the cultural area of Yaz I (Basafa 2017, Dana & Hejebri Nobari 2019, 2021, Vahdati 2016, 2018). The upper Atrak basin is an almost rectangular valley with a length of 90 km and an average width of 20 km. This region is one of the most important regions of northeastern Iran in terms of population movement because it connects the north of Kopet-Dagh to the interior regions of Iran and the center of the Iranian Plateau (Fig.2). Northeastern Iran has long been the place of entry of nomads from the northern steppes to the inner regions of the Iranian plateau. Due to the geological feature, Kopet-Dagh act as a barrier between the Karakum desert in the north and the fertile areas in the south, which cannot be crossed except through a few natural passages. 
More than 500 sites were identified in the archaeological surveys of the upper Atrak basin, among which 23 sites were dated to the Iron Age (Fig.3).

Iron Age Sites in the Upper Atrak Basin
The 23 Early Iron Age sites identified in the upper Atrak basin are listed in Table 1. In the surface survey of these sites, the only available data was pottery. In all Iron Age sites of this basin, the dominant pottery is Yaz 1 hand-made pottery. These pottery are poorly made, rough and in the range of buff and bright red, and the motifs are usually drawn geometrically with ocher and jujube red colors, and most of them are mixed with grog. 9 of the identified sites can generally be attributed to the Iron Age, and traces of Yaz I painted pottery were not found in the surface surveys. The pottery of these 9 sites are similar in form to the pottery of the Archaic Dehistan culture, but unlike them, they are in the buff and red spectrum.

Location based on ٍlevation Factor
The Iron Age sites of the region are located at an altitude between 1007 and 1718 meters above sea level. The size of the smallest site is 0.01 and the largest is 10 hectares. Examining the Pearson correlation coefficient regarding the area of the enclosures with the height factor shows -/299 (Table 2), which indicates a negative but moderate correlation. This means that as the height above sea level increases, it is expected that the size of the enclosures will decrease due to the limitations of natural factors.

Water Resource Factor
The distance of the Iron Age sites in the region from permanent water sources, including rivers and other running water sources, ranges from 0 to 6395 meters, and their average distance is 1441 meters. Pearson correlation coefficient/313. (Table 2) states that this figure shows the relationship between the direct and average level of significance between the size of the sites of the region with the factor of distance from permanent water sources. 

Land Use Factor
Pearson’s correlation coefficient between the size of the sites of the region with the soil type factor of the location of the sites shows -.054 (Table 2). This figure is weak and small. It is expected that there are large sites in the sedimentary plains and smaller sites on the edge of the plains and mountain slopes, and this is not the case in this area.

Slope Factor
Pearson’s correlation coefficient between the sizes of the sites of the region with the slope factor of the location of the areas is 0.72. (Table 2). The figure shows a very weak relationship between the size of the sites and the degree of slope of their location. 

Slope Direction Factor
Pearson’s correlation coefficient between the size of the sites of the area with the slope direction factor of the location of the areas shows -240 (Table 2). This phenomenon shows that some of these sites have not been used for a long time or that the different slope directions were not so important for the residents of this site in different seasons.

Communication Routes Factor
The sites of the region are located at a distance between 0 and 15355 meters from the main communication routes today. The Pearson correlation coefficient shows -114 (Table 2), this figure shows a very weak and small and inverse relationship. In other words, as we move away from the main communication routes, we should expect the size of the enclosures to decrease and become smaller.

Distribution of Iron Age sites in the Upper Atrak Basin
In this research, in order to obtain the distribution pattern of settlements in the region and to better analyze and understand the distribution of archaeological sites in the region and to find a pattern that fits environmental variables, the statistical method of cluster analysis has been used. Based on statistical analysis and their clustering, three patterns were obtained (Table 3, Chart 1).
Settlement distribution pattern 1: Settlement distribution pattern 1 includes 6 enclosures (Chart 1, Table 3). Due to the location of these types of sites in the landscape of the region and according to the distribution of these settlements on the level of the plain and the highlands, their small size, which is less than half a hectare, the economic method of these habitats can be assumed as temporary and seasonal settlements.
Settlement distribution pattern 2: There are 14 enclosures in this pattern (Chart 1). Due to the location of these types of sites in the landscape of the region and according to the distribution of these settlements on the level of the plains and the highlands, their small size, which is less than two hectares, the economic method of these habitats can be assumed as agricultural and livestock settlements.
Settlement distribution pattern 3: There is only one site in this group, and the reason for their placement in a cluster or separate pattern is its very large area compared to other sites. The size of this site is 2.2 hectares. The characteristics of this site, especially being located at a high altitude and a long distance from water sources and communication routes, and other characteristics show that it is similar to model 1, and only because of the difference in the size of this site, it is placed in a separate group.

Conclusion
The largest sites in the upper Atrak basin (except the IUA03 site) are located almost in a vertical line and very close to each other, Tappe Yam with 10 hectares, Tappe Ja’far Abad with 2.8 hectares and Sofalgaran-e Zadak site with 3 hectares, for a total of about 16 hectares from the total 33 hectares, half of the size of the Iron Age sites cover this basin. Today, these sites are located around the city of Faruj and almost in the middle of the plain. This area can be considered as the crossroads center of important roads in the region.
The important point in the reconstruction of the roads is the mountainous conditions of the region, which does not allow passage anywhere. With these conditions, there is only one possible way in the south, and that is today’s Binalud-Shah Jahan road, which goes from Quchan to Sabzevar. Near this road, there is Tappe Golshan Abad, which is actually located in the entrance area of this mountain pass. 
However, it is a little difficult to determine the northern route to pass Kopet Dagh and go to its north due to the number of valleys and the connection of some valleys with each other. By carefully examining the existing routes in the area and their connection with the Iron Age sites, a route is suggested that includes the sites of Tappe Yam, Dalan Tappe Kukach, Dalan Tappe Bozorg and Unnamed Tappe of Milanlu.
The western road along Atrak River connects the upper basin to the middle Atrak basin.
The eastern road also continues to the Kashaf River basin and the Mashhad plain without any natural obstacles.
Today almost all researchers agree that the people had Yaz I culture, nomads. Since Yaz I remains in a wide area of Greater Khorasan and the southern parts of Transoxiana, the route of population migration will inevitably pass-through Greater Khorasan through the north-south routes that connect the steppe regions of North Asia to its inner regions in the Iranian plateau. In this view, the upper Atrak basin is located in the area of Yaz I pottery culture, and due to its strategic location, it plays a very important role in the arrival of people with Yaz I culture to the inner parts of the Iranian plateau.

Abstract
The northern plains of the Alvand mountain range in Hamedan are known as part of the Median land and the capital of this period. Research and study on Iron Age III settlements with the aim of identifying and drawing an accurate pattern of the sites of this period was one of the goals of the writers in this region, which was carried out in recent years. Qale-dagh Tepe is one of the areas that have been reviewed and studied in this research. Qale-dagh or Aghdash area is located at an altitude of 2009 meters above sea level in the foothills of Arjanī mountain overlooking the Hamedan plain. The height of the area is 41 meters above the level of surrounding rangelands. The site was first identified and registered in 1381 AH and in 1385 AH in the comprehensive plan of archaeological survey of Hamedan city was reviewed. Despite much destruction, the site has not yet been studied and archaeologically excavated. Qale-dagh is a single period from the Iron Age III. It consists of single and dense brick building that can be seen in parts of the main walls and its gates. There is evidence of filling in the gaps between the back and the outside of the walls at an unspecified time. The pottery obtained from the study is small and contains non-significant samples of this period. There are questions about the condition of the area and its function in the heights of the Hamedan plain that this study has addressed. The research method in this paper is based on archaeological studies and comparative studies. Preliminary results show that Qale-dagh area is located in specific geographical location, architectural style, pottery data and compared with other sites of Median period such as Nush-I-Jan Tepe, Moush Tepe and Haji Khan is a religious place overlooking the capital of Med (Hegmataneh).
Keywords: Hamedan, Qale-dagh Tepe, Iron Age III, Median Period.

Introduction
In a series of surveys conducted from 2017 to 2018 regarding the spatial association of Iron Age III settlements in the Hamedan plain (Almasi, 2020), which is mentioned in historical sources as the first seat and political and governing center of the Median period, the known relics from the past years to the present, particularly the new relics in the last decade, were studied, and a question was raised. The question was “What were the function and nature of a group of monuments with characteristics such as individuality, being located outside the scope of settlement, similar style and method in architecture, especially in components such as the type of bricks, and finally their intentional filling at some points in time?”
One of these newly discovered monuments is a brick fortress named Qale-dagh Tepe located in the northern highlands of the Hamedan plain. The site is located in the foothills of the Arjanī Mountain with a height of 2130 meters above sea level. Aghdash Village is the closest modern village to it, which is located at a distance of 3.5 kilometers from it. The site does not have an access road from the village, so that one can only reach the site on foot by crossing some agricultural fields and barren lands.
The Qale-dagh site with coordinates Y:3869857.31-X:290962.58 is the only brick structure that is located on a natural bed among the hills of the Arjanī Mountain. The current size of the site is 1 hectare. However, the Qale-dagh site has suffered massive destruction over time, much of which is related to human destruction. The site was discovered in 2002 (Pazuki & Shadmhr, 2005) and surveyed in 2006 (Mohammadifar & Motarjem, 2006), and then the authors resurveyed it in 2017.

Data
The Qale-dagh site in appearance is divided into two sections: the northern section, which is a brick structure and remains up to a height of 3 meters, and the southern section, which is large and has a lower height (Map 3). The architecture of the northern section includes a thick wall with an approximate height of 3 meters and a diameter of 1.5 meters in the east-west direction. It appears that the wall has a buttress, since in the two sections of the wall, the remains of a brick pier with 1 meter in width and 2.5meter distance from each other can be observed. The distance between the two brick piers is filled with layers of pebbles and mud mortar (Image 2), Causing the wall to remain intact up to a height of 3 meters. On the northeastern side, several holes have been dug by unauthorized excavators, in one of which, the remains of more than 2 gates covered with a lancet arch can be observed from the outside (Image 4). From the inside of the gates, a corridor-like space with another lancet arch can be observed (Image 5). The width of the two gates is approximately 70 cm and lower than the height of 3 meters of the wall. The lancet covering of the arches is formed by laying bricks diagonally to each other. The materials used in the monument are bricks with dimensions of 42×23×11 cm and mud mortar with a thickness of 10 to 12 cm.
The pieces of pottery obtained from the surface survey include a bowl with an inverted rim, a simple bowl, a bowl handle, a base of a dish, and two pieces of a dish body (Image 7).

Analysis of Finding
In the survey of the architectural features and pottery pieces collected from the site, the history of settlement in the site appears to be related only to the Iron III period, as it was built on virgin soil. Such a procedure was used in some significant Median sites such as Nush-I-Jan (Stronach & Ruf, 2011), Moush Tepe (Mohammadifar et al., 2015: 236), ZarBolagh (Malekzadeh et al., 2014), Yalfan (Almasi et al., 2017: 70), Haji Khan (Hemmati Azandriani et al., 2019: 35) and Pishee (Almasi, 2020: 115).
In the northern wall, the remains of two brick piers are visible (Image 2), revealing the use of buttress in the construction of the main wall of the monument. The use of buttress, which is generally used on the outer front of the main walls of the monument, can also be observed in the sites of Nush-I-Jan (Stronach & Ruf, 2011: 16), Godin (Young & Levine, 1974: 116-pl.37), Baba Jan (Goff, 1977: 104-Fig.1) and Ozbeki (Majidzadeh, 2009: 343).
The gate with a lancet arch created in the Qale-dagh site is also similar to the ones in the sites of Nush-I-Jan (Stronakh & Ruf, 2011: 81), Godin (Gopnik, 2016: 293), Moush Tepe (Mohammadifar et al., 2015: 235) and Gunespan (Naseri et al., 2016: 131) (Table 1). The dimensions and sizes of the bricks used in the monument of the Qale-dagh site are similar to the dimensions of the bricks used in the monuments of sites of the same period (Table 2). Another characteristic of the site is the intentional filling of the monument (Images 2 and 3), so that this method of abandonment has been reported in the excavations of the sites of Nush-I-Jan (ibid: 163), Moush Tepe (Mohammadifar et al., 2015: 235), ZarBolagh (Malekzadeh et al., 2014), and Haji Khan (Hemmati Azandriani et al., 2019: 106). 

Conclusion
Owing to the geographical feature of the site, which is located in the foothills of the Arjanī Mountain overlooking the Hamedan plain and the connecting route of the Hamedan plain, it is possible to imagine a military use similar to the inter-road military forts. However, in the survey and comparison of the Urartian castles of the first millennium BC in the northwest, we observe considerable cultural data indicating long-term settlement in these places (Kleiss, 1980, Burney, 1966). On the contrary, such conditions are not observed in Qale-dagh. Hence, we can place emphasis on only the apparent characteristics of the site, such as the information obtained from the architecture and the results of comparing and matching it with the Median sites, particularly Nush-I-Jan, Moush Tepe and Haji Khan. From the excavations conducted in the three Median sites of Nush-I-Jan -Main Period, Moush Tepe and Haji Khan (Map 4), few findings of human activity (garbage production) were obtained, demonstrating a non-residential use in such places and their special use for the people. All the three sites were created on virgin soil, had intentionally filling, and were cleared before filling.
As no contemporary settlement was found near the site, a non-residential use can be considered for it. Furthermore, the height of the site above sea level and the steep slope of the site in the foothills of the Arjanī Mountain indicate that it is not easily accessible.
The intentional filling of monuments, which is carried out with special care in layers, can also be used to protect the monuments. Ghirshman associates the fillings with the change of religious attitude in the later period (Ghirshman, 1976: 10-11).
As supported by extensive evidence, the Qale-dagh site is extremely similar to the sites of Nush-I-Jan, Moush Tepe and Haji Khan.

Abstract
So far, the settlements of the Iron Age of Sarakhs plain have not been studied archaeologically, and on the other hand, the Iron Age of Plain Sarakhs represents the Yaz culture in the region and owes its name to the Yaz Hill area in southwestern Turkmenistan. Studies of the Iron Age culture of the Sarakhs Plain can reveal the basic information of this period and help to understand the general Iron Age of the Iranian plateau and the land of Turkmenistan. The purpose of this study, while identifying Iron Age settlements, is to analyze environmental factors to explain the patterns of Iron Age settlements in the Sarakhs plain. For this purpose, a field study was conducted in the plain and by studying the collected works and library studies. It was found that 16 sites have Iron Age artifacts. Some settlements are single-period and some have chronological sequences. The necessity of the present study is the unknown culture of the Iron Age of Sarakhs plain. Therefore, the identified Iron Age settlements of Sarakhs plain were analyzed from the perspective of environmental factors and their role in explaining settlement patterns. The output of maps and data of Iron Age settlements in Sarakhs plain showed that among the environmental factors influencing the determination of settlement patterns, Distance and proximity in the range of 300 to 900 meters above sea level, Location of settlements along the rivers of Sarakhs plain (linear settlement pattern) and large urban or rural centers (Mir Ahmad and Bazangan) up to 65 hectares (central location), Communication routes (communication route of Greater Khorasan in the Iron Age), In the formation and distribution of settlements have been more influential than other environmental factors. One of the most important results of the present archaeological study, Identifying the Iron Age settlements represents the culture of Yazd Plain Sarakhs, which will be used to measure the distribution of Iron Age settlements in this area to draw a very accurate and comprehensive perspective for understanding the social life of the people of that period.

Introduction
Sarakhs Plain as the research site has been a favorable habitat for the formation of various human communities due to its natural potential and optimal environmental conditions, including altitude, suitable soil and relatively favorable weather conditions. The study of the collected works of the Iron Age in the Sarakhs plain through archaeological investigation shows that some cultural traditions of southwestern Turkmenistan (Yaz culture) of the Iron Age were prevalent in the Sarakhs plain, and this plain is probably the link between the southwest of Turkmenistan and the northeast of Iran and culture. Its pottery is noticeably and significantly influenced by the culture of southwestern Turkmenistan (Yaz area). At the end of the Bronze Age, a new culture covers Central Asia and Southwest Turkmenistan, which is known as the Yaz culture, and it borrows its name from the Yaz Tepe area, located in the southwest of Turkmenistan and present-day Ashgabat. The pottery of this period is generally simple and in red, pea and gray colors.

Materials and Methods
The current research is based on the purpose of fundamental research and based on the nature and method of descriptive and analytical research. The method and tools of data collection in this research have been done in two ways: documentation and field activities. In the field survey, while surveying the plain in the region and identifying the settlements, the required archaeological information and evidence (pottery) were collected from the said sites and recorded in the database. In order to obtain scientific answers, the conventional methods of establishment patterns and GIS and Spss analyzes were used in this research, and after preparing the outputs and maps, two descriptive and inferential methods were used to analyze the questions.

Data
Our information about the land of Turkmenistan is based on the findings of Russian and Turkmen archaeologists’ excavations in the region and presenting their latest findings and reports, some of which have been translated and used, which can be used as library studies. he remembered at this stage, all written sources, images and maps were collected and analyzed. In the field investigation, while surveying the plain in the region and identifying the settlements, the required archaeological information and evidence (pottery) were collected from the mentioned areas and recorded in the database.

Discussion
At the end of the Bronze Age, a new culture covers Central Asia and Southwest Turkmenistan, which is known as the Yaz culture, and it borrows its name from the Yaz Tepe area, located in the southwest of Turkmenistan and present-day Ashgabat. The iron settlement patterns of the Ferns Plain have been formed with the influence of these environmental and natural factors. With these interpretations and based on this, in the current research, the relationship of each establishment and establishment patterns with respect to major and main environmental variables have been analyzed and measured.

Conclusion
During one season of archeology field investigation in Sarakhs Plain and study of collected works and library studies, it was obtained that the extent and continuity of culture in the place, the proximity and location of the settlements along the Tajan, Harirood, Kashafrood, Shurluq and Chakoodar (linear settlement model) in all the geographical directions studied in Sarakhs Plain showed that This plain has a direct relationship with the facilities and environmental conditions, such as the quantity and quality of settlements, the frequency and increase of the Iron Age settlements of the Sarakhs Plain compared to the previous period in terms of population density and the gradual complexity of the relationships between settlements and the relationship with the environment and Direct exploitation of water resources for agriculture and animal husbandry has been on the rise and in the last period of the Iron Age It increased all of a sudden and it is through this plain that this culture spread to other areas of South Khorasan and the plateau of Iran. In order to analyze and explain the settlement patterns of the Iron Age of Sarakhs Plain, a test was conducted between various ecological variables with the distribution of settlements based on the Pearson correlation coefficient and the effect of the significant level. The result of this study was the identification of 16 settlements from the Iron Age, which can be considered and evaluated from the perspective of environmental factors and the size of the sites. In the analysis and explanation of the Iron Age settlements in the Sarakhs Plain, the height above the surface of open water, the distance from rivers and other water sources, and the distance from communication routes with Pearson’s correlation coefficient with a significant level, had the greatest impact, and the other variables each implied They have left a significant impact on the Iron Age settlements of the Ferns plain. The results of Pearson’s correlation coefficient indicate that the distribution of Iron Age settlements in the Sarakhs Plain are regularized in relation to environmental and ecological capabilities and limitations, and these factors have played a significant role in the spatial distribution, determining the type of function and the importance of Iron Age settlements in the Sarakhs Plain. This has had an undeniable effect on the distribution of the population, the type of livelihood, the settlement patterns and their bodies. The Iron Age settlements that can be seen in this plain are the result of the specific geographical conditions of the region.

Abstract
From the end of the Late Bronze Age and the beginning of the Iron Age, the eastern regions of northwestern Iran were involved in a series of large-scale ethnic migrations, the scope of which had previously extended to the Caucasus. Crossings in the Caucasus Mountains led these migrations to the Meshginshahr and Ardabil plains and the high and green areas of Savalan Mountain. Undoubtedly, nomadic immigrants, during several centuries of migration along the routes, had found a series of low-risk and easy-to-reach routes in which they traveled constantly. The constant traffic along this route has left countless cemeteries along with it. Today, the Shahsevan tribes of Ardabil province inherit some of these ancient routes and use them regularly. The adaptation of the routes of the Shahsevan tribes to the linear distribution of the Iron age sites on them, proves such a hypothesis. In the present study, which has been carried out by field studies with an ethnographic approach in the western parts of Meshginshahr plain and the western and northwestern slopes of Savalan Mountain, why and how to conformity of the ancient routes of the nomadic tribes of the Iron Age with the Shasevan tribe routes have been discussed. Extent of Iron Age sites located in the route of Shahsevan tribes, how the sites are distributed in the summer places of the western slopes of Savalan and determining the most important and main ancient migration routes based on the distribution of the sites and their extent is another issue that has been addressed in this research. The results of reviewing and analyzing the available data show the complete compliance of the Iron Age sites with the longitudinal line of the migration routes of Shahsevan nomadic tribes. Most of the identified sites along the routes are of the cemetery type, which are much larger in summer areas than other places.

Introduction
According to the studies in the northeastern half of northwestern Iran, ethnic migration to the plains of Meshginshahr and Ardabil intensified from about the beginning to the second half of the second millennium B.C, shortly before the beginning of the Iron Age; The existence of large central castles and small satellites, as well as the numerous cemeteries that exist in this area, most of which are unrelated to the settlements, is a reason for this. It is not clear what the reasons for these sudden and mass migrations and the human factors or geographical conditions involved were, but what is clear from archaeological evidence is the existence of a north-south migration line from the Caucasus towards the southern parts of Moghan plain, Meshginshahr plain and the northern parts of Ardabil plain. In the Meshginshahr plain, the areas around the foothills of Savalan have received so much attention that many of these nomadic tribes migrated to these areas and many others for whom sufficient resources were not available went to the Sarab, Mehraban areas. And the eastern regions of East Azerbaijan province, as well as the northern regions, have moved rapidly. In addition to archaeological studies, one of the best methods for identifying and studying the routes used by the Iron Age migratory tribes in the Meshginshahr plain is study the routes that use present or in a few centuries. In this plain of Shahsevan tribes, a clear example today is the same immigrant tribes that passed through this area several thousand years ago; Some of them have chosen temporary accommodation and others have been forced to migrate to better places. The Shahsevan are one of the most important nomadic tribes in Iran who have preserved many of their ancient traditions. These nomadic tribes are a living example of a dead tissue, tribes that in today’s machine world, like their ancestors, have maintained their nomadic way of life; In the cold season, they descend from the green slopes of Savalan and live in local winters or in their villages, and again in the summer season, they start moving towards the summer. The adaptation of the modern routes of these tribes to the distribution of Iron Age sites is an important point; That is, the Shahsevan use the same ancient tribes in most cases. Of course, there may be small changes in the path, which may be due to inevitable geographical and human factors.

Discussion 
So far, there has been no research on the origin of the ancient roads of Savalan Mountain or their distribution. The present study was carried out by conducting an extensive field study in the western basin of Meshginshahr plain, northwestern, western and northward slopes of Savalan Mountain. The area in which the field survey was conducted covers an area of 980 square kilometers. According to the studies conducted in the present study and field visits to all modern settlements that have been studied in the area, there were 5 main roads for the migration of Shahsevan nomads in this area. Although these routes are no longer used and transportation is done by vehicles, the traces of all these routes and even their old titles have been preserved. According to indigenous peoples, herds of cows, goats, and sheep passed through and around the villages, along with camels carrying the necessities of life. The first route starts from the border area between Meshginshahr and Ahar and the confluence of Qarasu with Ahar Chay, and the other routes located differently in the eastern regions, respectively. Among these routes, the longest route is way No. 4. It should be noted that in all these roads, the nomads, after entering the wide bed of Qarasu river, migrated there and after resting and watering the cattle, they moved to the foothills of Savalan; These routes are selected in such a way that they cross several important rivers and in some of them they rested temporarily, such as Qarasu, Khiavchai, Meshginchai, Habashichay and Aharchay. The nomads crossed at least two or three of these rivers in each of these five routes. In general, 207 ancient sites were recorded along these 5 main roads that lead the Shahsevan nomads to the slopes of Savalan, which indicates that these routes were also used by the nomadic tribes of the Iron Age. The number of 181 sites (87%) are the cemetery types, which, are unrelated to the settlement sites and clearly belong to the Iron Age nomadic tribes. Almost half of the cemeteries are located in the slopes of Savalan, in the present summer tents of the Shahsevan tribes. Other registered sites are the central and satellite castles and settlement sites, all of which without exception were in the plains and along the route, and no traces of this type of sites were seen on the slopes. About 31% of the sites have an extent between 1 and 2 hectares. 25% of them have an extent in about 0.5 to 1 hectare and about 21% of the sites have an extent in about 2 to 4 hectares. 

Conclusion
Undoubtedly, the establishment of a route as an easy access route for migration has taken place over several centuries and millennia. The routes that were constantly traveled and based on experience, their quality have been tested for a long time and the most appropriate ones have been selected in terms of life and financial security. Looking at the general map of all the routes and the distribution of the Iron Age sites, the location of these sites on the route of these roads is quite evident. As you advance from the paths to the sides, the number of the sites decreases. This way of distribution of the sites shows that the sites are in a longitudinal line, and this longitudinal line is the route of modern and ancient roads. Examining the roads of this field contains other points. In all the routes, as much as possible, moving inside the valleys and next to the cliffs and slopes has been avoided. Only in the cases where they had to enter the river bed to rest and water the cattle, longitudinal movement along the path and inside the river bed was avoided, and entering the river bed only vertically have taken place to pass through. In all the routes, until reaching the low and steep slopes of Savalan, continuous movement has been made on the level of the plain and areas that have a full view of the surrounding environment. It seems that this was done to ward off possible natural, animal and human dangers. In general, the following can be obtained from the present study: Today’s routes are in line with the distribution of Iron Age sites; Most of the Iron Age sites located in the path and summer places of Savalan slopes are of the cemetery type; The located in the summer area and between them are more extensive; Many routes are interconnected and it was possible to change the route in all of them easily; Towards higher slopes, the number of ancient sites has been significantly reduced; Both along the route and in the summer places, the density of areas near and where water sources are much higher; In summer places, concentrated cemeteries or the accumulation of large graves in a small area, is rarely seen and many cemeteries, despite their large area, have low grave densities. The graves are scattered at a distance from the summers and their distance.

Abstract
In the summer of 2018, the archaeological excavation of Taghiabad Tepe land 2 was carried out in Varamin city.  The areas are located in the north of Taghiabad village and in the south of Ajorbast village of Javadabad Varamin. The excavation findings include the Bronze Age and Iron Age cultural periods. Among the valuable findings of this site were animal remains, which are very important to understand the subsistence system of this site. The most important goal of this article is knowing the subsistence economic system among the society living in the Iron Age based on zooarchaeological studies in Tagh. The main question that is raised in this research is, how can the animal species be identified in this area and how can the bone remain of animals be used in the reconstruction of the livelihood of the studied period? On the bone findings of the Iron Age area of Taghiabad (1&2) the traces of burns and cuts can be seen on some bones, which may have been caused by butchering. The basis of this research is based on studies on animal finds that were obtained in the archaeological excavations of Taghiabad Tepe 1 and 2. The findings of the research show the use of sheep, goat, cattle, gazelle, deer, susscrofa, urial, canine and birds’ species in Taghiabad Tepe 2. The study showed that animal husbandry played an important role in the livelihood of the people of that area.

Introduction
Depiction of subsistence, environmental and other living conditions of ancient societies is one of the most important approaches in archaeology and anthropology which is considered a multidisciplinary approach that requires archaeologists, biologists and ecologist cooperation.
By using zooarchaeology theories and based on analysis on animal remaining, archaeologists try to understand the different aspects animal’s livings and depict the interaction between the man and animal. 
Historically, zoologists only presented the recognizable species but recent studies on the remaining provide a more through insight. (Davis, 1987: 23) 
Identifying the species their prevalence and sex could be of immense value in the strategy of selecting the animal for herding and use of their flash. 
The main question in this study (Which is based on findings of Taghiabad site under supervision of Dr. Morteza Hessari in 2018 to identify the diet of residents in Taghiabad in Varamin Plain) is to scientifically identify the animal species and their role in meat provision. Moreover, if the residents were using domestic animals’ flesh or hunted animal and their ratio, if they were animal herders or farmers as well.
The most important goal of studying these remains is to reconstruct the animal-human behavior towards animals and his environment. 
Based on these introductions, identifying the species and being whether domestic or wild is one of the goals of this study.
With this approach the prevalence and ratio of species in an area is another goal.
The first review revealed the animal species which helped to identify the subsistence strategies such as animal herding and hunting were identified.
Understanding the human-environment relationship, ecologic, specifications of studied society and other conditions such as environmental changes could be achieved by bone analysis. (O’Conner, 2018). 
By studying the domestic animal bones, we could understand the herding methods and their goals of animal herding. 

Taghiabad Site
This site is located in agriculture zone of Adjorbast village in Pishva town of Varamin district. This site is named as Taghiabad1 and Taghiabad2.

Animal Findings
In this study the animal remaining which were recovered through the first season of excavation in 2018, have been analyzed, which dates back to Iron Age (1&2). First of all, the bones have been prepared by numbering and locus allocation. Then the species and the organs were recognized by using animal bones manual and bank of animal bones. 
Number of identified Specimens (NISP) Iron Age of Taghiabad 1
326 pieces of bones had been retrieved from Taghiabad1 related to Iron Age, 225 pieces related to Iron Age1 and 101 pieces related to Iron Age2 and 386 pieces belongs to Taghiabad2 (379 pieces related to Iron Age1 and 7 pieces from Iron Age2).
Species recognized in Taghiabad1 contains: sheep 114  pieces (71 pieces from Iron Age 1 and 43 pieces Iron Age2), goat 9 (6 Iron Age1 and 3 Iron Age2), gazelle 26 (19 pieces Iron Age1 and 7 Iron Age2), cattle 32 ( 19 pieces Iron Age1 and 13 Iron Age2), fox 1 piece related to Iron Age2, 8 pieces of canine from Iron Age1, small carnivorous 2 pieces from Iron Age2, equid 2 pieces from Iron Age2, equus 8 pieces (6 Iron Age1 and 2 pieces Iron Age2), sus scrofa 2pieces from Iron Age1, deer 1 piece from Iron Age1, 3 pieces of avian (1 from Iron Age1 and 2 Iron Age2), 1 piece of urial (Iron Age1) and 118 broken and non-recognizable pieces.

Number of identified Specimens (NISP) Iron Age of Taghiabad 2
63 pieces of sheep bones had been retrieved from Taghiabad2 related to Iron Age, 62 pieces related to Iron Age1 and 1 piece Iron Age2, goat 5 pieces (Iron Age1), gazelle 10 pieces (9 Iron Age1 and 1 Iron Age2), cattle 23 pieces (Iron Age1), canine 10 pieces (9 Iron Age1 and 1 Iron Age2), 1 piece of small carnivorous from Iron Age1, 2 pieces of equid from Iron Age1, 1 piece of equus from Iron Age2, 1 piece of equus asinus from Iron Age1, 11 pieces of sus scrofa from Iron Age1,  I piece of deer from Iron Age1, 1 piece of avian from Iron Age1 and 257 broken and non-recognizable.
34%were sheep and 2% goat bones in Taghiabad1, while in Taghiabad2 16% were sheep and 1% were goat bones. The found items were jaw, teeth, scapula, pelvis, ribs and vertebra bones. 
On some of the bones cut marks and burns were obvious. Cut marks are probably secondary to peeling and butchery process by a knife-like instrument. Abnormalities and bone reactions were seen on some items, most of them were adult to death.
Injuries which could be found on the bones are mostly manmade such as breaking the bones to have access to bone marrow, marks related to peeling process or cutting meat off the bones, burning marks secondary to cooking process and bite marks (Merritt, Sr 2016).
And the other injuries such as bite marks or signs of alimentation which caused by other animals.
17 pieces (11.8%) out of 144 goat and sheep bones and 3 (23%) out of 13 cattle bones were non adult I Iron Age1.
Most of the sheep and goats were adult at death which means they were exploited not only for primary product (meat) but also secondary products (milk, wool, breeding…). One of the advantages of goats is their reproductivity which makes their milk accessible. Cattles were being exploited not only for primary and secondary products but also for daily labor as transportation and plowing but duo to scarcity of their bones it could not be a precise finding.

Conclusion
By identifying the species from finding of Taghiabad, we could understand the strategies of subsistence such as herding and hunting and interactions among human- animals environment, which shows the important role of herding. The main sources of meat supply in Taghiabad site during Iron Age were sheep, goat and cattle (46.8%), sheep was the most found one then cattle and goat respectively. The reason for prevalence of cattle is its role in secondary products supply and its role in labor and transportation which is reflected in deformities on their bones. Equid, like cattle, were being used for labor and riding as well, most of them were adult at death which amplifies their role as secondary product supply source.
The most hunted animal were gazelles and sus scrofa (8.2% in Taghiabad1 and 5.59% in Taghiabad2). Comparison of findings from other sites of central Iran shows the equal importance of sheep and cattle herding among all of them in all Ages. Sheep was always more than goats. Study of the sus scrofa’s bones showed that except one sample, all the others were wild animals. Finally, we must emphasis that more precise results, require as more precise studies.

The artifact studied in this paper is a bimetallic sword made of bronze handle and an iron blade, which was excavated from the Tol ancient cemetery, located in Talash city, Gilan province, in 2001 by Mohammad Reza Khaltabari. This research aims to study the technology and pathology of the mentioned object by conducting comparative and archeological studies using the library method, conducting technological studies using the laboratory methods of radiography, metallography, and microstructural observations using a scanning electron microscope (SEM-EDS). The phase analysis of corrosion products was done by X-ray diffraction (XRD), as well as knowing the manufacturing method and identifying the types of damage and corrosion. The result shows that this work belongs to the Iron Age. Also, the tests performed on the two parts of the handle and the blade showed that the material of the iron blade is iron-carbon alloy. The amount of carbon in different parts of the body of blade is not the same and the handle is made of bronze alloy with casting and hammering techniques. It also has a galvanic corrosion effect.

Ziwiye, as one of the key sites for Iran’s North West Iron Age (Median kingdom), has many masterpieces kept in different museums and a long list of publications. The main part of this list consists of monographs that are written based on one or more limited objects from an out of context collection. There are few articles that comprehensively include the findings “attributed Ziwiye” and “came from excavation”. However, many articles have been published about Zavieh’s findings, but parts of this collection still remain unknown and do not receive enough attention. The corpus of bone arrowheads is one of them, some of which were found during archaeological excavations while others came to museums from antiquities dealers. These include: the Metropolitan Museum of Art in New York, Musée du Louvre in Paris, the National Museum of Iran in Tehran, and the Sanandaj Archaeological Museum. This article aims to introduce and categorize 51 bone arrowheads. Some of these were registered as ivories, but our research concluded that all of these were made of bone. In few instances, the production manner prevented the proper identification of bone versus ivory. Another examined point in this research is whether such arrowheads were produced for actual warfare or for prestige and symbolic use in ceremonial events considering their bone material. The examined samples from other sites show that bone can be hard enough to penetrate game and human body even with light protection such as archery. Bone for making arrowheads was used for hunting big games and some tribes still use them.

Abstract
Urmia lake basin is one of the most important cultural basins known in the archeology of Iran and has had a significant contribution in the historical and cultural evolution of northwestern Iran. Urmia plain and its surrounding heights have a special place among them. Due to the favorable environmental conditions in the Iron Age, important settlements were formed in the Urmia Plain. So far, forty-seven sites related to the Iron Age III (850 to 550 BC) have been identified in this plain that classified in the two parts of the settlement sites of the plain (39 settlement sites) and the defensive castles around it (8 castles). Among the forty-seven sites of Iron Age III (850 to 550 BC), thirty-two sites were formed on previous settlements and fifteen sites were formed for the first time. Among the thirty-nine settlement sites belonging to the Iron Age III of Urmia Plain, thirty-one sites with an area between half and five hectares are small villages and settlements. Three Sites are between five and ten hectares and three Sites are between ten and fifteen hectares. The two site of Goy tepe and Dizaj-Takieh, with an area between fifteen and twenty-four hectares, are considered among the large sites of Iron Age III of Urmia Plain. The distribution of ancient sites in the studied area is not the same, and among the thirty-nine settlement sites that have Iron Age III layers, a limited number are located in the higher areas of the western, southern and northern belt, and the absolute majority of the settlements are located in the flat plain of Urmia. Most of the settlement sites (about 76%) are less than a thousand meters away from water sources and rivers, and this shows that the water factor is the most important factor in the location selection of settlements in this era. During most of this period, Urmia region was considered one of the Urartian states. The results obtained from the analysis of GIS maps show that despite the pattern of Urartian settlements, which tends to settle and administrative management in mountainous and higher areas, the main and residential settlements of this era were formed in the lowland and their management was only in Military forts were located in higher peripheral areas.

Introduction
Urmia plain is one of the fertile areas in the northwest of Iran, and therefore it has been the focus of human societies from the past until now, and the evidence left behind, such as numerous historical hills, testify to the establishment and exploitation of this plain in different prehistoric times. And it is historical. Even though the archeology teams have investigated the Urmia plain in the past and identified important sites, but most of them only identified and registered the sites And they have not provided chronological and analytical information related to the trajectory of the formation and expansion of Iron Age III sites And this issue has caused the failure to present a detailed map of the pattern of settlements and the state of the sites in this period. Therefore, studying the state of settlements, their formation and expansion can be effective in understanding the cultures and settlement patterns of this period in this great plain. The archeological survey of Urmia Plain was conducted with the aim of identifying and investigating the ancient sites of the Iron Age III and also studying settlement patterns in two seasons in the fall of 2019 and the spring and summer of 2020. The present article, by examining the sites of Iron Age III in the Urmia plain, studied the formation and expansion of the sites according to variables such as height above sea level, water sources, distance and proximity to rivers and vegetation And based on their size, they are ranked and finally, it analyzes and reconstructs the regional landscape of Urmia plain in the Iron Age3 and the environmental patterns of the settlements of this period.

The text of the article and the main discussion
The beginning of the Iron Age III in the important settlement areas of northwestern Iran, including Hasanlu, has been determined following the massive fires that occurred at the end of the Iron Age 2 and led to the destruction of the settlements of this period. Chronologically, this era coincides with the emergence of a new pottery phenomenon, which Young (Young 1965:70) called the new Buff Ware horizon, that appeared in many sites in western Iran. Based on this, in the northwest of Iran, especially in the Urmia lake basin, the Iron 3 period has been introduced at the same time as Hasanlu layer 3. Urmia Plain, as the largest plain on the western shore of Lake Urmia, witnessed extensive changes in the first millennium BC. The importance of the Urmia plain, and its location at an important crossing in the first half of the first millennium BC, has caused the attention of the governments of Urartu, Assyria and even Manna. Urmia Plain in the Iron Age III due to these favorable environmental conditions, especially the flow of permanent and abundant rivers, numerous springs, suitable and fertile land, rich pastures and abundant hunting, has received more and more attention and received a significant population. A population that relies on agricultural livelihood more than anything else, and the location of settlements has been done near stable water sources and main rivers And these places have been chosen according to the topography, slope and type of soil so that water supply to the land can be done easily and also have fertile soil. Among the forty-seven sites of Iron Age III (850 to 550 BC), thirty-two sites were formed on previous settlements and fifteen sites were formed for the first time in this settlement period. Among the thirty-nine settlement sites, thirty-one sites have an average area between half and five hectares, six areas have an area of between five and fifteen hectares, and two areas have an area between fifteen and twenty-four hectares. Among the four major settlement and non-settlement sites of this region, namely Goy tepe, Bari, Ismail-Agha Castle and Dizaj-takiyeh, two sites of Ismail-Agha Castle and Bari Castle are located in the mountainous areas overlooking the Urmia Plain And as fortresses and defensive fortifications, and two settlement sites, Goy tepe and Dizaj-takiyeh, have served as the central places of the plain. By looking at the distribution map of the settlements of this era and paying attention to geographical variables such as distance and proximity to water sources, agricultural lands and the size of the areas, the pattern of settlements in the region can be determined. Most of the sites are formed in the plain. Considering that water has always played an important role in the formation of these establishments and is considered an important indicator for their analysis, It is obvious that the flat areas and near permanent springs and rivers have been given more attention by these tribes. The higher areas of Urmia region have fewer settlements. These settlements can be considered as seasonal settlements, because they were forced to leave the place immediately when the amount of water decreased. Therefore, it seems that the permanent settlements are mainly formed along the permanent rivers. Other geographical variables such as distance and proximity to fertile and suitable agricultural lands and altitude above sea level are effective in this increase in population and settlements.

Conclusion
Among the 187 hills and historical sites identified in Urmia Plain, forty-seven sites from the Iron Age have been identified. Two pottery traditions have been identified, including the Urartian pottery tradition and the local pottery tradition with simple Buff Ware with the influence of late Manna pottery. In addition, suitable environmental conditions have made the Urmia plain one of the main agricultural areas of Azerbaijan, so that this area is considered one of the key areas in the development and population increase in the northwestern plateau of Iran (Biscone 2003:167). Settlement patterns in the Urmia Plain, including residential settlements in the bottom of valleys and low plains and close to fertile lands and water sources, especially permanent and abundant rivers in the region and the creation of fortresses and defense fortifications in the higher parts and on top of the rocks. The establishment of residential centers in the Urmia plain was done during the dominance of the Urartu in the alluvial lands of the plain And the main military centers have been built in the form of strong fortresses in the surrounding heights of this plain and The small sites in Urmia plain, which are less than nineteen sites and their size is less than three hectares, are residential units and small villages that were engaged in agriculture And other settlements of this era in the Urmia plain, which number up to eighteen settlements, are between three and fifteen hectares in size. And they are managed by two large and central sites, Goy tepe and Dizaj- Takiye. Therefore, according to Chrystaller’s model, Goy tepe, as the largest settlement site in the Urmia plain, controlled the central and northern sites of the plain, and Dizaj- Takiye, in the second place in size, controlled the southern sites of the Urmia plain.

Abstract
Earthquakes have always been considered a threat to human settlements. According to the results of archeological studies, one of the behavioral patterns of humans in the face of earthquakes has been to permanently change their place of residence. The fact that the major part of Iran’s plateau is located in one of the earthquake-prone areas of the planet makes the research and investigation about the impact of these natural events on the human way of life, especially in the prehistoric era, to be studied more. In this direction and with the aim of assessing the impact of this natural phenomenon in Central Zagros and in order to know how humans react to this phenomenon, it has been studied. Our main question in this research revolved around how ancient earthquakes can be identified in archaeological contexts, and based on what evidence? What were the effects of this destructive phenomenon on the change in people’s biological patterns in the period after the incident? The information of this research has been collected from the archaeological excavations of Godin Tepe, Kangavar and Baba Kamal Tepe Tuiserkan from the Bronze Age to the end of the Iron Age III BC. In the following, based on the evidence of the severity of the destruction caused by the earthquake, an attempt has been made to reconstruct the intensity scale of the earthquakes based on the Mercalli scale. As a result, it was determined that the occurrence of destructive earthquakes with an intensity of more than 6 degrees on the Richter scale in the area of the investigation, especially in the Bronze and Iron Age, was not unrelated to the impact of climate change caused by the intensity of melting glaciers and the change in the hydrological conditions of the earth. After the Late Bronze Age, the events caused by this event caused the relative collapse of many settlements until the Iron III period, and practically at this time, the population of the region was reduced to the minimum possible.

Introduction
Throughout history, villages and cities have always been threatened by cultural or natural disasters such as war, fire, earthquakes, floods, and storms. Earthquakes are natural events that have been important causes of damage and destruction for humanity. The land of Iran, due to its location in the middle part of the Alpine-Himalayan orogenic belt, is always exposed to high-intensity earthquakes and is known as one of the centers of destructive earthquakes.
Studying and researching the remaining signs of ancient earthquakes in Iran according to archaeological data can provide information on long-term seismicity in different parts of this land for researchers. By using archaeological data and matching their information with specific regional geological conditions, it tries to recognize the occurrence of earthquakes that occurred in prehistoric times and their effects on the formation of settlement patterns. 
In this regard, the Kangavar Plain and the eastern region of Central Zagros have been studied and researched, focusing on the archaeological information of Godin Tepe and Baba Kamal Tepe. This research aims to investigate and identify the archaeological studies carried out in Godin Tepe and East Central Zagros to study and investigate the events that are suspected to be natural earthquake hazards in Godin Tepe and Baba Kamal. Also, the role and effect of these earthquakes in the distribution of settlements after the earthquake will be studied in the region, seeking to answer questions such as: How can the earthquake during the settlement of Tepe Godin and Tepe Baba Kamal be recognized? In what period of the settlements of Tepe Godin and Baba Kamal and with what approximate magnitude did these earthquakes occur? How can the role and effect of these earthquakes be explained by the change and distribution of settlement patterns in the post-earthquake era of the region? In the investigations and field studies, the evidence and signs of earthquakes in the Bronze Age of Godin Tepe Kangavar and the Iron Age of Baba Kamal Tepe Tuysarkan have been observed, which can be the hypothesis proposed in this regard.

Discussion
The investigation of different cultural layers showed that the Godin site experienced at least three important events that changed the lives of the people at that time. Evidence of these events can be seen in layers III5, III4, and III2 in the Bronze Age in different years between 2400 and 1650 BC. Yang, the explorer of Godin Tepe, believes that the earthquake in these phases caused destruction and destruction in the buildings, which caused the settlement to leave and the site to be abandoned at the end of phase III2. Among the damages caused by the earthquake in Godin Tepe and Baba Kamal, the following can be mentioned:- Collapse of ceilings and walls;
• Collapse of ceilings and walls;
• Debris left on the floor of the rooms;
• Crushing of healthy pottery under the debris;
• Humans being buried under the rubble and being killed by falling bricks;
• Cracks in the walls
• Abandonment of the site after the earthquake
Using the empirical relationships and the Mercalli intensity scale (MMI), we can attribute an average magnitude of 6 to Godin III2 and Iron III Baba Kamal events, and an average of 7 to Godin III4 and III5 events. 
 According to the archaeological surveys conducted in the studied area, it can be seen that the region has experienced a decrease in human settlements and population collapse in the periods after the Godin earthquakes. The reduction of settlement areas during different phases of the Middle and New Bronze Age compared to the previous layers is observed in the plains of Kangavar, Nahavand, Asadabad, Tuysarkan, Malair, Sanghar, Sahne and Borujerd. In layer III2, the number of sites with artifacts from this period increases in the region. Young and Henrikson believe Godin III2 pottery at the same time as this phase, or probably at the end of this phase, we see an increase in the nomadic process, and it is likely that this issue has influenced the increase in the number of ancient sites. 
During the Iron Age, the central Zagros region underwent changes that led to the reduction of human settlements in Iron Age I. Archaeological data show that there was no population density in Iron Age I/II in areas like Kangavar Plain. Several abrupt climate changes occurred during the Holocene epoch. This change in weather conditions, along with the earthquakes in the region, could have been a factor that affected the settlement of human populations and settlements in the region in prehistoric times and caused a change in the settlement pattern and a decrease in human populations.

Conclusion
In this study, in order to investigate the seismicity of the eastern central Zagros region and the earthquakes that occurred in the Bronze and Iron Ages of the region, the collection of evidence and documentation of the earthquakes of the mentioned periods, obtained from archaeological excavations, was collected. Earthquake evidence in Baba Kamal Tuiserkan Tepe was obtained in the form of disturbed layers with cracks in the Iron Age III clay structure. Also, these signs have been observed in the form of ruins and human remains found under the debris, scattered artifacts and pottery on the floors of residential houses, and cracks on the walls in the Bronze Age of Godin Kangavar Tepe. Godin Tepe has witnessed three destructive earthquakes in phases III5, III4, and III2, which, in addition to the destruction that followed, caused the area to be abandoned for a long time. The abandonment of the area can also be seen on Baba Kamal hill, which was without settlement until the Parthian period.
After the Godin III period until the end of the Iron Age I and II, the reduction of settlement areas is observed not only in the Kangavar plain but also in most of the surrounding areas of the Kangavar plain in the east of central Zagros. However, some researchers have pointed out the change in weather conditions as another reason for the decrease in the number of settlements in the region, and climatological research has proven that during this period, climatic dry events occurred in Southwest Asia. According to the seismicity of the central Zagros region and the evidence of earthquakes from Godin Tepe and Baba Kamal, these climate changes, along with the occurrence of earthquakes in this region, are both factors that have provided unfavorable conditions for life in the region at the same time. Based on the data obtained from the Godin and Baba Kamal sites, a magnitude of 7 was estimated for the Godin earthquakes of layers III5 and III4 and a magnitude of 6 for the earthquakes of Godin layer III2 and Iron Age III of Baba Kamal.

Abstract
Damage to cultural artifacts after discovery occurs due to various factors. One of these harmful cases is moisture originating from underground water, which appears as soil moisture, and over time, due to the oxidation process and the salts and ions in the water, as well as the incompatible pH of the environment with the texture and construction of the artifacts, it aggravates the process of destruction. In line with the mission of archaeometry as a bridge between archeology and other sciences, hydrogeology is used in this study in order to protect ancient artifacts. Iron Age Museum of Tabriz is located in the central area of the city and among the young Quaternary sediments that form the free aquifer of Tabriz. Underground water is one of the main factors causing corrosion and decay in the bones in this museum site. There are various solutions for lowering the water table locally, which according to the location coordinates and technical requirements of the site, the best method is to use underground water pumping. In this study, by using the available data in the study zone which is taken from the Tabriz urban train project and the data obtained from the Regional Water Company of East Azarbaijan, by using computer methods, the appropriate amounts of water pumping have been simulated according to the optimal water level drop and We define the placement of bones in a dry position. The use of new sciences for archeometric purposes is the main goal of this study and an attempt is made to solve the problem of destruction of ancient bones by establishing this connection.

Introduction
The discovery of ancient bones belonging to the Iron Age of the first and second millennium BC in the area of Tabriz Blue Mosque in 1997 is an important event in the field of archeology and ancient anthropology in Azarbaijan. When this ancient area has been discovered, studies have been carried out in the fields of dating about these bones and studies related to the origin and the migration (Kasiri, 2019) and the conservation and restoration of the graves in the Iron Age Museum area in 2016 was carried out by Majidi and Razani. In recent years, the effect of humidity on buried organisms in the soil has been the subject of many researchers’ studies. Soil moisture can play an important role in decomposition (Swift et al, 1979). Fluctuations of groundwater in the soil is one of the most important factors affecting microbial activity in the field conditions (Lund and Goksoyr, 1980). Iron Age Museum of Tabriz is located in the central area of this city and among the young Quaternary sediments that form the unconfined groundwater aquifer of Tabriz. Tabriz aquifer has an alluvial nature, which has expanded as a result of the Mehran Rood River flowing in its ancient path and creating numerous meanders during geological time. Hydrogeology as a new branch of earth sciences and engineering studies the condition, behavior and hydrological characteristics of the layers of the earth. As a porous environment, the basement contains soil grains, and the empty space between these grains can be saturated with water and provide a path for the flow of groundwater. The voracity of water movement in the basement compared to the surface currents is very low and varies from a few centimeters per year to several meters per day. Due to passing through various minerals and rocks, groundwater often has a significant amount of different solutes and has relatively high electrical conductivity (E.C). These solutes can cause a lot of damage to cultural works by sedimentation or crystallization in case of evaporation of groundwater. The climatic conditions of each region are different in the occurrence of damaging moisture factors and their effects in different seasons of the year (Nawai, 2016). The amount of humidity in the environment, which can cause destruction due to freezing with the participation of the temperature change parameter, will cause serious damage due to the transport of new solutes and sedimentation at each stage and the recrystallization of previous sediments. In addition to the above, the penetration of moisture through underground water can change the pH of the environment, and this change causes the destruction of cultural works by increasing the acidity.

Discussion
Iron Age Museum of Tabriz, as a result of its archaeological excavations, 108 graves were identified, based on the typology of pottery and metal artefacts and the method of burial and comparing them with the collections discovered from the excavations of Hassanlou Hill and Dinkhah Tepe, dating from around 1200 to 800 BC and the period of Iron Age I and II have been estimated for them, which of course is relatively consistent with the results of carbon 14 dating of these sites (Hojbari Nubri, 1381 and 1383). Its cultural, historical, social and economic nature, along with the aesthetic quality and historical and cultural importance of that area; The type of constituent materials and the composition and method of construction of the works found in it, the value, validity and information and messages hidden in those findings and how they are used are valuable documents of its cultural heritage collection. These works, mainly from archaeological excavations, have been obtained over several years, and their preservation in relatively inappropriate conditions has led to the progress of damage caused by the burial of these objects in the ground, and after a rather long period of time, they will disappear (Bagherzadeh Kasiri, 2016, 8). Based on the studies of Tabriz Urban Railway line 1, water level data is available near the study area of Asr Ahan Museum site, and according to the principle that the groundwater level almost follows the topography, it is possible to estimate the groundwater level in The location of the museum was found. For this purpose, the water level data was collected in the study boreholes near the study area (Table 8) and the map of the ISO lines of ground water in the study area was drawn (Fig. 10). It is necessary to explain that ISO lines or equipotential lines of groundwater are curves on each of these curves, the level of ground water has the same values and the map of parallel lines shows the changes of the level of ground water in the study area. It is possible to draw this type of map both manually and by using software that allows for interpolation and drawing. Next, modeling of groundwater drawdown due to pumping from the extraction well was done using GMS software version 16.4. For archeological stratification, before installing the drilling machine, a manual well should be dug to the desired diameter and to the depth of the ground water, and after reaching the depth of the underground water, the drilling machine will continue drilling from inside this well until it hits The stone should be foamed.

Conclusion
The Iron Age Museum site of Tabriz is one of the prominent sites in the northwest of the Iran, which is facing major problems due to the groundwater infiltration. This research uses information and data of the studies of the aquifer of this region with taking account to the problem of how to intervene in the ancient sites. It has provided a solution to deal with the problem of groundwater in order to reduce its flow, and in this regard, by introducing the place of preliminary evaluations using speculation and Finally suggests a piezometric well to start working in this area and control the groundwater level. Noting that the change of seasons and amount of rainfall can affect the condition of groundwater to some extent; Therefore, by changing the flow rate and duration of pumping, other values of drawdown can be achieved. For this reason, it is suggested that if the plan is implemented, a piezometer well should be drill as close as possible to the museum site so that the condition of the groundwater as well as the amount of its draw done due to pumping from the extraction well can be under immediate control. To prevent the water used in the green space and other uses of the museum site from returning to the area of ancient graves, drainage channels should be used between the area and the main space of the museum.

Abstract
Predictive models are a component of GIS-based statistical approaches, which hold an important place in archaeological research due to advances in relevant theories and tools. Predictive models, developed through the statistical processing and analysis of environmental variables that influence site location, aid in understanding the cultural and natural landscape of the study area and contribute to the development of plans for improved cultural heritage management. This article, employing a statistical-analytical approach and data from archaeological surveys, aims to present a predictive model for a part of the eastern Kurdistan region where archaeological surveys have not yet been conducted. Prediction modelling was performed using the MaxEnt machine learning method, with eleven factors as natural variables and presence data (areas) required for modelling. The model area was divided into two experimental sections (Bijar and Dehgolan) and a prediction area (Qorveh), as the prediction model for Qorveh city was based on the natural variables and presence data from Bijar and Dehgolan cities. Finally, the prediction map was divided into four classes: very high, high, medium, and low suitability areas. The very high suitability area, which comprises 10% of the total model area, contains 59% of the Iron Age sites in eastern Kurdistan. It was found that vegetation cover, land use, and distance from rivers were among the most influential factors in the model. Also, the initial data in Qorveh indicate that 62% of the sites are located in an area comprising 8% with very high desirability, supporting the accuracy of the prediction. The AUC statistic is 0.836, and the finding value for the model has been calculated as 0.82, which indicates a prediction model with an approach value close to 1.

Introduction
The use of GIS and statistical modelling to map possible locations of archaeological sites has increased over the past decades. (Stefan & Sîrbu, 2010; Niknami et al., 2007; Alirezaei et al., 2019). Currently, archaeological prediction models are a powerful tool for preventing natural and human damage to historical and cultural resources (Danese et al., 2014), and for increasing the efficiency of archaeological field activities and cultural heritage management (Howard et al., 2016; Balla et al., 2014). Statistical modelling, as a perspective for identifying suitable areas for selecting prehistoric settlements, has been widely used by geographers and archaeologists (Sharafi et al., 2016; Verhagen & Dragut, 2012; Kaimaris, 2018). This method can be effectively considered a form of archaeological exploration. This paper aims to develop a concept for creating a prediction model using the MaxEnt method in the Eastern part of Kurdistan, to evaluate similar studies in archaeology, and to determine settings and suggest ways to optimise such approaches. Simultaneously, using a statistical approach based on GIS, the prediction model, and archaeological survey data from the eastern part of Kurdistan, it identifies the most favourable locations for the formation of Iron Age settlements. Accordingly, using environmental and archaeological data from Bijar and Dehgolan counties, a prediction model for Qorveh county has been developed using the MaxEnt method. Due to the lack of access to archaeological data for Qorveh County, the study area has been divided into two sections: experimental and prediction. This approach allows for predictions in the Qorveh region based on data from the experimental area (Bijar and Dehgolan counties), despite the absence of the required data. This method can thus be proposed as a study approach, with related recommendations, for another similar research.
Research Method: This research employed field and library (descriptive-analytical) methods, utilising the Geographic Information System (GIS) for the preparation and interpretation of GIS maps to analyse the settlement habitats of 96 Iron Age sites in eastern Kurdistan (Bijar, Qorveh, Dehgolan). The MaxEnt model was used to predict the distribution of Iron Age sites in eastern Kurdistan.

Data
The present study used a digital elevation model with a spatial resolution of 28 metres. Any change in these data will result in changes in climate, livelihoods, and other factors (Khosrowzadeh & Habibi, 2015: 109). The digital elevation model is used to extract new information such as slope, slope direction, and land curvature. This information is relatively common and significant, and is generally used in predictive models in archaeology. Land curvature data have also been used, which are defined as the rate of slope change (Whitworth, 2011: 469). The prediction model in this paper will be implemented using the principle of maximum entropy (MaxEnt). Such predictive modelling in archaeology requires two types of input data: environmental data (environmental variables that have a direct or indirect effect on the location of historical sites based on archaeological studies) and data related to archaeological sites, also known as presence data. The study area covers the political geography of Bijar, Qorveh, and Dehgolan counties. This study aims to make the most accurate prediction of Iron Age archaeological sites in Qorveh county using presence data (sites) from surrounding areas such as Bijar and Dehgolan counties. Given the similar climate and landscape in the eastern part of Iranian Kurdistan, the prediction of site formation locations in Qorveh County will be presented based on the MaxEnt prediction model.

Discussion
The final result of the prediction model for the eastern part of Kurdistan was based on the frequency ratio (FR) of the land cover and land use variables, which were among the most influential factors in the model. Their impact coefficients were estimated to be 24.3 and 32.6, respectively. Based on the classification of the forecast map, the low-desirability region covers the largest area within the forecast range, comprising 72% of the total. In contrast, better results can be observed due to the reduction in the area of regions in the high-desirability group. These regions, categorised as very high and high-desirability groups, comprise 10.5 percent and 7.5 percent of the total area, respectively. In contrast, it includes the largest number of areas, accounting for 89 percent of the total. These areas comprise 57 and 29 areas, respectively. While the areas with the highest potential are highlighted, they significantly reduce the area available for archaeological investigation.

Conclusion
MaxEnt modelling requires the use of presence data (areas). For this purpose, the prediction model is defined to include two categories of areas. First, the experimental area contains presence data (areas) as well as environmental factors and variables to configure the prediction model. Second: Prediction area; this section and perspective include the city of Qorveh in the eastern part of Kurdistan. The experimental area for this modelling contains 96 presence data points (areas) with an Iron Age chronology. Of these, 25% were used as test data and 75% as training data. Modelling with the MaxEnt method identifies the most influential variables by examining each one. Factors such as vegetation cover, land use, distance from the village, and distance from water sources are among the most influential variables on the model results. In this case, MaxEnt statistical analysis of other variables is also presented. Examination of the altitude variable shows that it has the greatest impact on sites within the altitude range of 1378–1400. The greatest impact of rivers on the sites occurred at a distance of 1000 metres. From 1000 to 3000 metres, the impact was least, but from 3000 to 5000 metres, the influence on site location became significant again. It has been found that at a distance of 2000 metres from villages, the likelihood of site formation is greater than at greater distances. The prediction map is divided into four groups based on the specified threshold value mentioned earlier: very high, high, medium, and low suitability areas. According to this division, the very high suitability area covers 10.5% of the total model area, and 59% of the sites (occurrence data) are located within this area. The high, medium, and low suitability areas include 30%, 6.5%, and 4.5% of the sites within these areas, respectively. Given that the very high and low suitability prediction areas are small but contain the largest percentage of sites, the model can be considered predictive.

Abstract
A series of field activities including two seasons of survey and excavation at the Shahneh Poshte cemetery of Babol on the northern slopes of the Alborz Mountains in central Mazandaran in 2018 and 2019 resulted in the discovery of a collection of human graves and burials scattered throughout this 11-hectare site. Due to the mass of destruction caused by unauthorized excavations in the cemetery, several disturbed graves were observed without any classifiable information. In contrast, by conducting scientific excavations in the 16 trenches, a total of 39 identifiable and Readable human burials were found and then the collection of information and archaeological findings related to each burial was recorded and classified. In this study, we attempt to answer questions about the existence of possible burial methods and patterns and the meaningful characteristics of these variables by studying a set of different aspects including burial practices such as the position and orientation of the body, position of face of hands, architectural structure of the graves, gender and age of skeletons, individual and group burials, and burials with and without objects. The results of absolute dating and comparative studies indicate that this cemetery belongs to a long time span from the 11th and 12th centuries BC (Iron I) to the 4th and 3rd centuries BC, i.e. the Achaemenid to the early Parthian period (Iron IV), and therefore cultural materials of this cemetery are comparable to intra-regional ancient sites in Mazandaran as well as trans-regional sites in the Gorgan Plain, the Central Plateau, and especially the Gilan region. Our research also shows that the Shahneh Poshte graves follow a specific pattern in some burial aspects including the supine position and the direction of the face to the south and therefore have long-term burial traditions.

Introduction
The Shahneh Pashte cemetery is located adjacent to village of Kamikola and southwest of the Khoshrudpey city and 21 kilometers south of the Babol (Fig. 1) (Saedian, 2014: 321). This cemetery was excavated over two seasons in 2018 and 2019 by Hassan Fazeli Nashli. The result of these excavations was the identification of 39 human burials in situ (28 graves) (Fig. 2) which provide a set of valuable archaeological data such as absolute and relative dating, burial methods including the position and orientation of the bodies and faces, the position of the hands and the structure of graves. Based on the whole of archaeological data, the site can be dated to the late 2nd millennium B.C (late Iron I) to the mid-1st millennium B.C (Iron IV, 3rd - 4th centuries B.C / Achaemenid to early Parthian). More precisely, the absolute dating on 5 skeletons uphold this period. Based on archaeological studies between 39 burials, 29 burials belong to the late Iron I (late 2nd millennium BC) to Iron III (burials 1-11 and 22-39) are called “Iron age I - III Group” and the other 10 burials (burials 12-21) can be dated to the 4th and 3rd centuries B.C (late Achaemenid to early Parthian) that are called “Iron age IV Group”, considering the absolute dates of the two burials and their spatial relationship.

Discussion
The study of the Shahneh Poshte burials shows that a set of methods were used to place the deceased in grave which are divided into two general categories: lying on the sides and supine. These two general modes include a total of 11 sub-modes. In general, in the entire Iron Age in this site (I-IV), the lying on the sides includes 13 burials (33.3%) including 4 burials on the right and 9 burials on the left, supine 15 burials (38.5%) and also 11 burials (28.2%) lack any recognizable signs. In more detail, during the Iron I-III period, there were 8 contracted burials (28% of total) of which 4 were on the right and 4 on the left. In addition, 12 burials (41% of total) were buried in supine. Also, 9 burials (31% of total) were of unknown status. In the Iron IV, there were 5 contracted burials (50% of total) all of which were on the left and no right-sided burials were found. Moreover, 3 burials (30% of total) were buried in supine. Finally, 2 burials (20% of period) were classified as undetermined burials due to extensive damages (Fig. 3-5). Regarding the position of the hands of the skeletons, during the Iron I-IV, a total of 16 positions were observed which can be classified into three general groups: lying on the sides, supine and unknown. In addition, the first group includes 6 subgroups (25% of all), the second group is divided into 9 subgroups (54% of all) and the third group is divided into 9 cases (21% of all) as unknown (Fig. 6-7). In Shahneh Poshte, three types of grave architecture have been identified. The first is a simple pit, second is a simple pit with a clay cover and the third is a pithos. Of the 28 graves in site, 26 graves (93% of all) are simple oval pits, of which 20 graves belong to the Iron I-III (71.6%) and 6 graves (21.4%) belong to the Iron IV. The second method, a simple pit covered with big clay fragments includes only 1 is from Iron Age I-III (3.5% of total). Also the pithos burial consists of only 1 grave (3.5% of total) from Iron Age IV (Fig. 8-10). In terms of gender and age of the deceased in this cemetery, total of 9 burials (23% of all) were identified as male, including 8 burials (27.6%) in Iron I-III and 1 burial (10%) in Iron IV. In addition, there were 14 burials (36% of total) as female including 12 burials (27.6%) in Iron I-III and 2 burials (20%) in Iron IV. Also, of the total burials, 16 burials (41% of total) were disturbed (Fig. 11-17). In addition, 7 different positions of the bodies were identified in relation to geographical directions including: south-north 5% of all, east-west 2.5%, west-east 23%, northeast-southwest 10.5% of all, southwest-northeast 10.5%, southeast-northwest 10.5%, northwest-southeast 15% and also an unknown direction 23% of all burials (Fig. 18-19). It is worth noting that for the orientation of face, during all periods, the dominant method was the south direction with a total of 23% of all burials, and especially 20.5% of all in Iron I-III, it was certainly the most common burial method. It seems that this method was not a priority in the Iron IV and was used less often. After that, the north direction was the most common method with 15.3% including 10.2% in Iron IV and 5.1% in Iron I-III (Fig. 20-21). Regarding other study characteristics, 67.8% of the total graves are individual and 32.2% are group graves. Among the first group, 53.5% of the total is related to Iron I-III and 14.6% are related to Iron IV. In addition, group graves comprise 32.2% of the total graves of which 621.5% are related to Iron I-III and 310.5% are related to Iron IV (Fig. 22-25). Finally, about the possession of objects, in total, 70% of all burials were buried with burial objects and 30% did not contain any goods (Fig. 26-27). Finally, regarding the amount of possession of objects, in total, 27 burials (70% of all) were buried with burial objects, and only 12 burials (30% of total) did not contain any burial objects or grave goods.

Discussion 
Human skeletons in Shahneh Poshte cemetery are mostly buried in individual and group graves, including 28 graves which mostly include simple pits, one case of a simple pit with a clay cover and one pithos. In fact, the architectural of the graves was mostly in form of simple pits. A simple pit grave with a clay cover is quite unique in this site and a similar the grave has apparently been found only in one grave in the Lefork cemetery of Savadkuh which has been dated to Iron Age III (Abedini, 2017: 154). Third group of tombs is pithos type that has many similar older and contemporary examples in Mazandaran county. Among the numerous similar examples in the Iron Age of Mazandaran, can mention the children’s tombs in Gohar Tepe (Piller and Mahfroozi, 2009: 19) and cemetery Amirkola in Savadkuh (Abedini, 2017: 154), as well as Qaleh Kuti I cemetery (Fukai and Ikeda, 1971: Pl. XIX, Fig. 2) and Kaluraz in Gilan (Fahimi, 2002: 106-107), Tepe Gyan (Contenau and Girshman, 1935: 12), Maral Tepe of Uzbeki (Majidzadeh, 2008: 135-136) and Dinkhah Tepe (Muscaerella, 1974: 75). In addition, this method reached its peak of use during the Parthian period such as Taq bustan in Kermanshah (Kambakh Fard, 1998: 45), Liarsang-Ben cemetery in Gilan (Jahani et al., 2023: 38; Jahani et al., 2018: 114), and especially in the central Zagros basin (Mohammadi Far and Hojabari Nobari, 2004) such as Sanandaj (Khosravi et al., 2018: 317), Marivan (Mohammadi Far and Sarraf, 2006; Masoumian and Rahimi-Galugahi, 2012: 428) and several points in the city of Hamadan and its surrounding areas (Azarnoush, 1975: 56, vol. 7; Dailer et al., 2013). The graves of Shahneh Poshte are scattered in different parts of the cemetery and it does not seem that a specific space of the cemetery was dedicated to a specific group or class of people in this society. The group graves are in the form of two-burial and three-burial graves with a slight difference in depth and space compared to each other, although the attribution of some of these group burials to each other has been ambiguous. However, the spatial proximity of the skeletons and their burial objects and the difficulty in distinguishing them from each other led to the attribution of some of them to a single grave and it seems that even despite a slight difference in depth, there was a clear awareness in creating a single grave for multiple skeletons. Usually, the deceased were placed in the grave in various positions, either contracted (lying on their sides) or supine with different positions inclined to the right or left. The positions of the hands are usually in front of the chest and face and sometimes in line with the body and the legs are also bent in three different degrees: less than a 90-degree angle (high, inclined inward towards the abdomen and spine: grade 1), 90-degree angle (medium, perpendicular angle to the spine: grade 2), and more than 90-degree angle (low, open angle to the spine: grade 3). A few are also supine and extended in line with the body.

Conclusion
The study of the burials of the Shahneh Poshte cemetery shows that there were a group of methods and rituals related to the burial of the dead, some of which were used more than others and, in other words, became a burial tradition. Regarding the position of the dead during the Iron Age and during the use of this cemetery, all the conventional methods of placing the deceased in the grave were used in the Shahneh Poshte area and despite the slightly higher number of supine method, it does not have a significant advantage over the lying on sides method and both methods can be seen as burial methods and traditions in great abundance. Also, the supine method was the most common burial method among women with 71% and men did not have any dominant method. In the discussion of the architectural structure of the tomb, the common tradition and method, the usual method is a simple oval pit but there are two unique methods, one is a simple pit grave covered with pottery fragments and the other is a pithos burial, each of which was used in the form of a grave only as a specific method, not a burial tradition. Finally, based on the set of burial characteristics of the Shahneh Poshte cemetery, it can be seen that this site is comparable in many aspects to sites within the region in Mazandaran and adjacent the region especially Gilan and the Central Plateau. It can also be considered that the set of burial methods and traditions of the Shahneh Poshte cemetery is homogeneous and identical to other contemporary sites in Mazandaran and to some extent a continuation of some pre-Iron Age burial methods in this region.
