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.
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.

Abstract
The settlements of the Qazvin Plain, particularly at Tepe Qabrestan and Sagzabad, demonstrate a continuous sequence of metallurgical development in the prehistoric period of this region. The aim of the present study is to examine the functional aspects, manufacturing technology, chemical composition, microstructure, and alloy phases of metal artifacts recovered from the Iron Age levels of the Sagzabad site. In this context, the study aims to address key questions regarding the production processes and manufacturing techniques of the artifacts, the alloying practices employed, as well as the chemical composition and formation conditions of the identified corrosion products. To achieve these objectives, various analytical techniques were employed, including XRF for determining the chemical composition. The results indicated the presence of various alloys, including copper–arsenic, copper–antimony, tin bronze, and nearly pure copper. Metallographic analysis of two samples with preserved metallic cores revealed a cast structure with a distinct core, providing important information about the manufacturing techniques. In addition, SEM-EDS observations confirmed the presence of α-phase dendrites and the formation of γ-phases associated with copper–arsenic and copper–antimony alloys. Elemental analysis results indicate varied patterns in the use of copper–arsenic and copper–antimony alloys, suggesting that ancient metalworkers possessed considerable knowledge of how to achieve desirable mechanical properties in their metallic products. In addition, the identification of silver inclusions and sulfide intermetallic compounds within the microstructure allows hypotheses to be proposed regarding the types of ore sources used in the metal extraction process. The identified manufacturing technologies ranged from two-part mold casting to the production of chisels with both spiral and simple cross-sections. The analyzed artifacts comprise decorative, ornamental, and Functional objects. This typological and technological diversity provides a comprehensive view of Iron Age metallurgical practices at Tepe Sagzabad.

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.
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.

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.
