Abstract
Central Zagros as one of the significant Iranian archeological perspectives has attracted the attention of many archeologists during the recent century and especially from the 1950s. It seems that the rugged lands of this near east region have been the cradle of many cultural evolutions during the history and the prehistoric periods. Although central Zagros due to its adjacency to the central Iranian plateau, Mesopotamian and southwest of Iran lowlands, and also the northwest mountains of Iran has been of concern mostly for the cultural remnants of the prehistoric societies, yet it has been a strategic and important region during the historical and even Islamic period. Among them we can mention the complex of Taq-e Bostan on the north of Kermanshah located on the ancient path of “The great Khorasan road”. This complex is on the hillsides of Parkuh and surrounded by thickets and a lake which cause it a particular situation throughout the history. This complex owes its fame to the Sassanid rock relief which has been visited by Abeh Pushan in 1792 for the first time. However, Herzfeld studies are the first scientific investigations on the historical complex of Taq-e Bostan. On the other hand, the
conducted excavations by Mr.Kambakhshfard in 1969 led by the accidental discovery of some pithos graves by municipality workers, resulted in achieving the evidences of a Parthian cemetery with more than 50 pithos graves and also remains of a village related to Parthian period. According the archeological investigations and studies on the ancient paths of the western Iran, or the surveys have been done in the region and ninety years background of archeological studies about this area, no report regarding the prehistoric existence of this complex has been presented. Morad Hasel site is the closest prehistoric site to this complex which has been identified and surveyed by Mr. Hassan Rezvani and it is related to the chalcolithic and Bronze Age. During the surveys and visits of Ali Hozhabri in the summer of 2013, some evidences of a chalcolithic site have been identified in the western park of Taq-e Bostan complex. This site was surveyed and its surface findings were transferred to the C.H.H.T organization for filing and documenting. Regarding the nature of the findings which were collected during the field survey, the aim of the present study is to introduce this significant site and to present a relative
history for the site’s artifacts. In the following, the overall image of cultural structure of this site is recon structed with an analytical view and with regard to the chronology and the location of this site.
Keywords: Central Zagros, The Western Park of Taq-e Bostan, Chalcolithic Age, Kermanshah.

Conclusion
This site is located on the north of the current city of Kermanshah, Taq-e Bostan historical complex; with northern longitude of ″16 ′23 °34 and eastern latitude of 47″54.7′7°. Altitude of this site from the sea level is 1395 m and is one-kilometer length and 300 meters width. This site is located on the west of Taq-e Bostan, in the western Park of the complex and on the hillside, surrounded by pine trees and close to a basin with a boiling fountain. This basin known as Taq-e Bostan Sarab is one hundred meters far from the east of the site. The site is one kilometer far from the north of Qarasu River. On the rather steep slope of the mountain and some deep clefts have been made on its both sides by heavy equipment. The Parthian cemetery of Taq-e Bostan is formed on the Taq-e Bostan western park site’s remnants. Fortunately, the pine jungle around this site has prevented the urban construction and the field is preserved. However, since the Parks and green spaces organization of Kermanshah is beside the site, and in 2005 Kermanshah municipality decided to build a parking in this area and started to excavate in two parts of the site. The result of this earthworks were discovery of some Parthian pithoi graves which were unfortunately destroyed; although C.H.H.T stopped their progress but those clefts are still obvious and gradually they turned in to a dumping ground for city wastes and building debris. Later the municipality started to expand the west Park area of Taq-e Bostan with some changes. Except the known sites and caves around Taq-e Bostan which are far from the historical monuments, up to now Taq-e Bostan complex has been known and studied for its Parthian, Sassanid and Qajarian cultural remnants. Discovering a prehistoric site in this complex can emphasize its importance, not only for the historical and Islamic period but also the prehistoric (Chalcolithic) period. The Godin excavations can be considered as the base for western Iran chronology of central Zagros, but it seems that contrary to Kangavar plain, and in compare to eastern plains of Zagros, Mesopotamian ceramic culture was more widespread in the western plains of central Zagros such as Mahidasht during the fourth millennium B.C. accordingly, the chalcolithic chronology in Kermanshah and Mahidasht plains can be studied based on the excavations conducted in Siyahbid and Chogha Maran. Based on the chronology of the neo-chalcolithic period of this site which its evidences have been obtained on the workshop no. 3, handmade red ware and black ware ceramics with black decorative patterns have been found related to this period. The proposed date for the neo-chalcolithic of Mahidasht is 3000 – 3600 B.C; comparison of the discovered ceramics indicates  the concurrency of this site with GodinVI: 1 and neo-chalcolithic layers in Siyahbid and Chogha Maran. Clearly, ceramics are the most important and significant cultural material of the near east. Due to the degradation and destruction, the surface cultural material of this site is just shreds. The neo-chalcolithic ceramics of the western Park of Taq-e Bostan complex are buff ware with vegetal temper and light red coating color. These ceramics are handmade, properly baked and medium quality. Among the surface ceramics of this site, no patterned shred was found but regarding the appearance of these ceramics, they can be related to neo-chalcolithic, specially the common rolled Rim bowls have been seen among the collected samples of the surface. Considering the clefts in this site made by the blades of the road construction equipment, the cultural material accumulation can be seen in this site. Ceramics are this site is comparable with the ceramics of GodinTepe in Kangavar plain and Siyahbid in Kermanshah plain.
 

Abstract
By author has been studied the areas of Jam, Riz, Saadat Shahr, Marvdasht, and Kazeron in Fars and Bushehr provinces from years of 2000 to 2007. During these surveys, 19 cave and rock shelter of Paleolithic period from plains of Jam and Riz are identified in southeast of Bushehr province that from this number, 5 sites related to Paleolithic period. The pastoral nomads of inhabitant in Bushehr province are most important groups of user these caves and rock shelters in plains of Jam and Riz. In this research are studied destruction factors of first of communities in south Zagros. The mining operations, non-standard construction, and excavations of illegal are the main factors of destruction in these sites. Furthermore, non-standard gathering the stone tools from Paleolithic period by archaeological students, and also unfamiliarity of the managers of cultural heritage of this region, are other the factors destruction these sites. So, for prevent the destruction of these sites must be done training local people and participation them in tourism this area. Introducing these tourist places in different ways is an important task to introduce these traces. Also, the build of museum site in the Paleolithic caves, and training of local children and tourists children, are from other effective actions. In this research for the first time, is study pathology of Paleolithic sites in Iran. The method of doing this research is descriptive-analytical. The analysis of this study is more reliant on information, founds, and data. So, in this research following questions are raised: Which is factors the main factors of destruction the sites of the Paleolithic period in South Zagros? And, what practical measures are there to protect these ancient sites? 
Keywords: Pathology of ancient caves, Paleolithic sites, South Zagros.

Introduction
Due to human activities are destroyed many of ancient traces as stone tools or faunal remains in the sites, caves, and rock shelters. The Mining operations, non-standard construction, and road construction are from main factors of destruction in ancient sites. The recent surveys are showed some of the caves and rock shelters of Paleolithic period in south Zagros affected by livelihood issues of pastoral nomads and indigenous people have been destroyed (Dashtizadeh, 2000, 2005, 2006a, 2006b, 2006c, and 2006d). The purpose of this research is survey destruction factors in these ancient sites.
In this research for the first time, is study pathology of Paleolithic sites in Iran. The method of doing this research is descriptive-analytical. The analysis of this study is more reliant on information, founds, and data. So, in this research following questions are raised: Which is factors the main factors of destruction the sites of the Paleolithic period in South Zagros? And, what practical measures are there to protect these ancient sites? 
For doing this research has been used from field surveys that by author gathered from areas of Jam, Riz, Saadat Shahr, Marvdasht, and Kazeron in Fars and Bushehr provinces from years of 2000 to 2007.

General description of studied areas and main factors of destruction of Paleolithic sites and protective solutions
By author has been studied the areas of Jam, Riz, Saadat Shahr, Marvdasht, and Kazeron in Fars and Bushehr provinces from years of 2000 to 2007. During these surveys, 19 cave and rock shelter of Paleolithic period from plains of Jam and Riz are identified in southeast of Bushehr province that from this number, 5 sites related to Paleolithic period (Dashtizadeh, 2009). The pastoral nomads of inhabitant in Bushehr province are most important groups of user these caves and rock shelters in plains of Jam and Riz. Furthermore, 17 caves and rock shelters of Paleolithic period have been identified from the plain of Saadat Shahr (Dashtizadeh, 2006c, 2006d, and 2012). Of course before that 17 caves and rock shelters of Paleolithic period have been identified from the Marvdasht plain in the northeast of Shiraz. From the Kazeron plain have been identified numbers of 27 caves and rock shelters of Paleolithic period. For this research is again studied the basin of Maharloo lake (Barfi, 2007). Generally, mining operations, non-standard construction, excavations of illegal, pastoral nomads, unfamiliarity of the managers of cultural heritage of this region, and non-standard gathering the stone tools from Paleolithic period by archaeological students are the main factors of destruction in Paleolithic sites in the area of south Zagros. First these archaeological sites are must be on the national monuments list. One of the main duties of the Cultural Heritage Organization is training the local community and tourists to preserve national monuments. Education and awareness of people this region (As the main guardians of the cultural heritage), is important work in this direction. The build of museum site in the Paleolithic caves, and training of local children and tourists children, are from other effective actions.

Conclusion 
Generally, mining operations, non-standard construction, excavations of illegal, pastoral nomads, unfamiliarity of the managers of cultural heritage of this region, and non-standard gathering the stone tools from Paleolithic period by archaeological students are the main factors of destruction in Paleolithic sites in the area of south Zagros. It seams, first these archaeological sites are must be on the national monuments list. One of the main duties of the Cultural Heritage Organization is training the local community and tourists to preserve national monuments. Education and awareness of people this region (As the main guardians of the cultural heritage), is important work in this direction.

Abstract
Dehloran plain, because of geographic location itself has always been one of the population centers in the southwest of Iran. Also, this area, because of permanent and seasonal rivers and fertile fields has been a good place to live in a long time. In terms of natural landscape, this plain is divisible into three regions of eastern, central and western. The first area (eastern area) is includes east of Dehloran plain, that consists of peaks and slopes of Zagros Mountains. The second area are including of lands near to these mountains. This area by floods of these mountains is covered with rocks and coarse-grained sediments. The third area (western area) is includes settlements from Neolithic to contemporary period and farming fields. Overall, these three areas for a long time, because of the rocky shelters in Zagros Mountains have been good place to live a human. On the other hand, these areas because of animals and suitable vegetation them, have been provider of food for human groups. Furthermore, because of existence conglomerate sediments eastern highlands of Dalpari in Dehloran, human access has been easy to rich sources of raw rock for make stone tools. This area that is more than 30 kilometers long, on the way of Zagros Mountains of Dalpari near to Dehloran plain and Dasht-e Abbas, covered with stone tools. These stone tools are containing of indicator samples of points, blades, centripetal core, Levallois chips. These samples can be sign of human existence at least from the middle Paleolithic period. So, existence of the Neolithic settlements to the late Islamic era is sign of a long process from the settlement human in this area.

Introduction
In 2015, in order to organize the western waters of the country, survey and identification programs frontier areas located in the provinces of Kermanshah and Ilam in format of ten programs for survey and identification (plan of tropical) were implemented. These programs were containing of identification water transfer routes, place of construction of dams, and drainage networks. The drainage network number 23 was studied by the author. This network was containing of Patk plain in Musian (eastern half of Dehloran), that water supply project it was on the agenda of the government. Therefore, all this plain with license number 943141/00/6495 with date of 2015/11/15 from Iranian center for archaeological research was carefully surveyed. During this survey (includes the southernmost tropical system in the south of the Ilam province), in addition to the identification of sites and ancient hills was surveyed wide area in the east of the plain that were many stone tools in it. The Dalpari area is several kilometers along the Zagros Mountains continue. The research background in relation to this area is shows the main focus of researchers on the sites belonging to the Neolithic period to the historic period and hasn’t been studied previous periods. The only survey of the Paleolithic period was done by Mohsen Zeynivand in year of 2015 in network number 22, that it has led to the identification and introduction of stone tools of type a Biface (Zeynivand, 2016 & 2017). So, the eastern half of Patk plain in Musian hasn’t been surveyed prior to this study. 

Introduction of identified traces 
A: Rock shelters
In a small part of the Dalpari Mountains a large number of small and large holes were identified with shelter form. These holes and shelters in sedimentary and conglomerate layers in low height hills have been formed with weak structure. The depth and width of the crater some of these holes and shelters 2 to 3 meters and high to 1.8 meters. Because of weak cement structure conglomerate and the existence of sedimentary layers of silicate and clay of non-condensing environmental degradation factors as wind and rain, it seems, these holes and shelters over time have been changed a lot. Due to a lot of stone tools inside and around of these sites, probably they were remnants of older refuges that used by humans (at least late) in the Paleolithic period. Today this area, because of a water fountain is used by pastoral nomads this area.

B: Surface finds
Mainly, at the surface of this area, can be seen stone tools includes blades, centripetal core, levallois chips, points, scrapers, and micro blades. The stone tools can be seen in all of plain, but in around the rivers less seen. Because of the continuity of distribution stone tools at surface this area, all of this range is introduced as a zone. During the survey this area, samples were collected from different parts of it. In total, 129 sites were encoded and distribution of the findings recorded. This area that is more than 30 kilometers long, on the way of Zagros Mountains of Dalpari near to Dehloran plain and Dasht-e Abbas, covered with stone tools. These stone tools are containing of indicator samples of points, blades, centripetal core, Levallois chips. Dating of samples collected is between 40,000 years and 16,000 years ago (Olszewski & Dibble, 1993).

Conclusion
Probably, dating stone tools collected of the Dalpari is between 40,000 years and 16,000 years ago. At most of surface the land in this area (except for a small area in the mountains) isn’t seen evidence of permanent deployment such as a cave or shelter. However, in these areas is identified little evidence of temporary and seasonal deployment of human in a small part of the northern mountains of the area. In this area, can be seen conglomerate and sedimentary layers, and because of the natural erosion including wind and rain have been created holes and shelters. These holes and shelters due to loose cement conglomerate and sedimentary layers is young seems to arrive, but stone tools around them doesn’t show this.

Abstract
Despite of studies about acceramic Neolithic period in west of Asia (especially Levant area), little has been done archaeological activities related to this period in Central Zagros. The Central Zagros is one of the important areas of west Asia that in this area has been done sedentary, domestication animals, and cultivation for first time. In Central Zagros, Seimare River is the largest river. The Seimare archeology project was done based on surveys and excavations archaeology in dam basin of Seimare. The Dangjoun from sites was excavated in related to Seimare archeology project in year of 2010. In total, 70 square meters was excavated from this site that led to discovery three phase of settlement. In Dangjoun wasn’t achieved of terra cotta ware, but architectural remains were achieved from all trenches with different quality. The architecture this site has been affected from Central Zagros environment. The materials used in this site are taken from the surrounding environment. This study was done with a fundamental purpose, and method of data amassment in this research is library – field method. In this research, in addition to the introduction and description architecture of Dangjoun, the complete descriptive has been done about architecture of A and B periods of acceramic Neolithic. In this regard have been explained specific architectural features of each period in Anatolia, Syria and Northern Zagros (in Iraq). Main questions of research: Due to the architectural condition of this site as right corner architecture, and …, this site belongs to, which period of acceramic Neolithic period? Due to the permanent architecture in Kapargah (that including of homes four corners, and built of homes on the ground), it seems, this site is belong to period B of acceramic Neolithic period and can’t be attributed it to earlier periods.

Introduction
In the history of human culture, the Neolithic period is of particular importance. The Neolithic period is including from 11000 to 7000 BC. The human societies has been experienced many changes in this period. Some of the most important changes in this period as: Starting and developing agriculture and animal husbandry, permanent establishment, population increase, long distance commerce as obsidian, skill in the production of stone tools, beginning of metallurgy, production of pottery, use of fire in the industry, indication of personal ownership of objects, accumulation of wealth and beginning of social inequalities, construction of public and religious buildings (Hole, 2000: 192; Byrd, 1994). However, the most significant consequence of Neolithic revolution was emergence of a compound economy with emphasis on domestic plants and animals (Hole, 1984). On the other hand, production of pottery in this period is led to cleave Neolithic period into two periods: Acceramic and ceramic Neolithic. According to the hints top, the main concept of Neolithic period is with food production, appearance of village, and architecture. The Central Zagros is one of the important areas of west Asia that in this area has been done sedentary, domestication animals, and cultivation for first time (Zeder, 1999). The Central Zagros because of the strategic position and placing in between areas like Mesopotamia, Khuzestan, Azerbaijan and central parts of Iran, and also Due to the appropriate environmental facilities in this area as: fertile fields, good agricultural lands, abundance of water resources, … has always been a concern for human societies for a long time. Main questions of research: Due to the architectural condition of this site as right corner architecture, and…, this site belongs to, which period of acceramic Neolithic period?

Research findings
The Kapargah is located in Lorestan and part of Kuhdasht County and Konani region. The nearest city to this site is Badreh city in Ilam Province. The Kapargah is located in Cham Ghoileh valley and for difficult transit this valley, in this area is living of wild animals. In terms of size, the Kapargah is small size and about 2000 square meters. Around this site rarely is obtained stone tools. This site is to form of rectangle and has 70 meters long and 30 meters wide. The Kapargah isn’t located on the floor of the plain, and with the passage of time have been created sediments about 6 meters on the site. The distance of this site to the river is about 50 meters, and surrounding lands are very prone to farming and animal husbandry. It seems, primary village because of located in between mountainous plains has been built on a gentle slope. The architecture this site has been affected from Central Zagros environment. The materials used in this site are taken from the surrounding environment. Workshop 1 was created with 5 m long and wide, and relative to workshop 2 had less architecture. All the walls have been made with rubble from mountain and river and sticking together with mortar. In this site was discovered three phases of architecture that hasn’t been seen structural difference between phases. Workshop 2 first was created with 3 m long and wide and then developed, and extent it was reached to 54 square meters. In this workshop too, discovered three phases of architecture that all the walls have been made with rubble from mountain and river and sticking together with mortar.

Conclusion
Due to the permanent architecture in Kapargah (that including of homes four corners, and built of homes on the ground), it seems, this site is belong to period B of acceramic Neolithic period and can’t be attributed it to earlier periods. The difference in architecture in two trenches this site probably because it is workshop 1 has been created in around of the village and this area has been temporary residential homes. Two warehouses in this workshop show each home has its own warehouse. The climate situation of this area has been influenced the construction of houses. Because of the air temperature above zero in this area, the walls aren’t thickened.

Abstract
Tapeh Giyan in Western Iran, which is well known to the archaeological academia, is one of the most important prehistoric mounds in Central Zagros which has always been noticed by both Iranian and foreign archaeologists. The last season of field works at Tapeh Giyan was done under Ali Khaksar in the spring and summer of 2012 in order to determine its boundaries. For this purpose, 27 test pits were dug all over the mound, and in trench no. 12, a distinctive burial was discovered. Since none of the 122 graves excavated by the French expedition over the years 1931 and 1932 were documented, the excavation continued on this newfound grave; it was entitled no. 123. Its burial’s corpse’s position is a combination of bent and supine position, and its mouth is abnormally wide open; also, there are 19 funerary objects buried with it. In the present study, we are going to discuss the very unique burial position of this grave together with its historic and comparative aspects.
Keywords: Iran, Central Zagros, Tapeh Giyan, Burial, Bronze Age.

Introduction
Tapeh Giyan is a well-known archaeological site located 12 km from the west of Nahavand and 70 km from the south of Hamadan city, in the marginal parts of a small town with the same name. As it was mentioned above Tapeh Giyan is situated in the Northern peripheral parts of the town, and it meets residential units in the south. This mound is 350 m long and 150 m wide, and it is also 17 m higher than the surface of the adjacent lands. Lastly, the average height of the mound is 1600 m above the sea level. This archaeological site was excavated by French archaeologists (Contenau and Ghirshman) over the years 1931-1932 and its results were published in 1935. Giyan became less important till it was once again excavated in 27 test pits in 2012 in a research program for delimitating the mound and determining its boundaries. In the course of conducting this research program, the true area of the mound was determined. The mound spreads towards the south, east and also southeast, and it continues to the beds beneath streets and houses; this was confirmed by an in-situ burial located in the outer parts of mound’s boundaries dating back to the middle Bronze Age. The burial was to excavated and studied owing to the fact that the other 122 burials were not completely/fully documented by the French expedition. 

Discussion 
Tapeh Giyan is one of the most prominent archaeological sites in Central Zagros from which artifacts from 5th to 1st millennia have been reported in the course of archaeological excavations. This mound’s excavations could undoubtedly bridge the gap between non-scientific/unsystematic and scientific/systematic archaeological excavations in Iran. At that time, the system of stratigraphy (was not interpreted in the same way) it does now, and what was regarded really important during excavation was finding the origin of a particular pottery from the region of Giyan as well as the bronze artifacts of Lurestan. Considering the fact that most information about Tapeh Giyan has been yielded from its burials, it cannot be reliable enough from the stratigraphic point of view; however, it’s been about 50 years that the chronology covering mid-3rd millennium to 2nd millennium B.C.E. in western Iran has been established based on Tapeh Giyan’s excavations. 
Overall, 122 graves have been excavated in scattered spots of Tapeh Giyan at different depths during the previous excavations at Giyan. 119 graves in the depth of 9.5 m. from the mound’s surface, and 3 graves in depths of 11.5, 13 and 14; one in each, have been dug. These graves are in form of simple elliptical pits in the ground. The children’s skeletons have been buried in almost large jars. The corpse body and skeleton have been bent and it seems that this position pattern had not been obligatory. In the course of this season’s excavation, an accompanied burial was found in test pit number 12 in the depth of 200 cm from the mound surface. In this grave, 19 objects have also been found together with the skeleton; this assemblage of objects includes: 6 ceramic pots, 4 bronze pots, 1 bronze spear, 1 bone object, 2 bronze earrings, 2 bronze rings which were joint to the jaws, 1 metal ore-like blade, and 2 bronze rings on elbow bones. These objects which are considered funerary objects and grave gifts were mostly put above skeleton’s head and at the same level with the skeleton. As we know, the funerary objects represent both functional and ritual importance in burying traditions, and the funerary objects in this newfound grave constitute majorly potsherds. 
The notable point about this burial is the skeleton’s position pattern; this skeleton’s upper part along with its pelvis is both in a complete supine position, and its mouth is unnaturally open. Considering the existence of two bronze rings at the joint of the upper and the lower jaws (mandible and maxilla), we could conclude that some changes have been exerted on the primary status of the burial. The jaw bone and the teeth are completely sound except for the premolars which have traces of wearing on them; all this makes us presume that this person would do an activity with them when he had been alive. His legs are tucked in toward his stomach on the right side of his pelvis. The toes and ankles of his both legs were below the right side of pelvis, and the pelvis itself had been dislocated after burial due to external pressures. The bone of left leg’s femur was located on the pelvis, and the femur’s head had been situated on the right hand’s elbow as well. 

Conclusion
According to the paleoanthropological studies, this skeleton belongs to a hefty man aging 35- 40 years old. This skeleton, despite being almost well-preserved, bears some evidence which indicates a number of changes applied in the primary burial including lack of some hand and foot phalanges as well as the existence of the rings put on the two papillae on the lower jaw joint. It is highly likely that these rings have caused the mouth to remain open, which could imply sort of burial tradition. According to Ghrishman’s excavations in 1933 and 1934 in the Tapeh Giyan, the earrings have been among the funerary objects of men. In addition, the rings couldn’t be earrings in that in addition to the rings, there are two earrings in the grave. Because of the abundant muscles and vessels existed between upper and lower jaws, the rings could not be placed there in a living human. Therefore, the rings must have been placed in these places after death intentionally. Furthermore, the symmetrical position of the rings in the two papillae on the lower jaw joint, the impossibility of putting and removing the rings easily in this place and also having no evidence of the natural post- depositional processes, in other cases such as earrings, and the object place on the collar bone, are the reason for rejecting the natural post-depositional processes and accidental disturbance. Ceramic wares constitute the majority of the gifts. These wares are all morphologically typified as Giyan (IV, III) and Godin types which all date back to mid-third millennium through late- second millennium B.C.E. Existence of metal objects in this grave and studying the type of bronze alloy utilized in these objects’ structures shows that the method and technique used in producing these dishes and pots has been lost wax method, and beside that hammering has been applied in making the other metal objects. Finally, on the basis of the historic-comparative studies, and also with considering the chronology of prehistoric cultures at Tapeh Giyan, we can infer that this burial belongs to (middle) Bronze Age and dates back to a period of time from 2500 to 2000 B.C.E.

Abstract
The two most prominent types of material cultures in eastern Zagros are Bronze Age black burnished pottery (3rd millennium BC) and grey Iron Age pottery (second and first millennium BC) that were dog out during archaeological expeditions are being investigated and reconstructed. The technique of firing these two types of pottery will be analyzed in the present study. The main objective of this research was to reconstruct the similar conditions and techniques of these two pottery class using experimental archaeological methods and practical reconstruction of traditional kilns. Along this route, the technical similarities and differences are discussed, relying on archaeological data and comparing it with reconstructed samples. In this regard, two samples of each of the Bronze Age and Iron Age potteries were reconstructed and samples were produced and refurbished by traditional kiln that utilize modern laboratory facilities and precise temperature-measuring devices and are heated in the firing process. The results of the try and error tests indicated that baking with chemical reduction and emergence of gray color is the most important common feature of difference of gray pottery with other pottery assemblages. The firing technique and the structure of the kilns are the most important factors in distinguishing the two types of bronze age and iron age pottery assemblages. What is certain is that with the evolution of the furnace structure, the heat generated from about 700 ° C in the gray Yanniq period of the Bronze Age has increased to about 1000 ° C in the Iron Age specimens, resulting in a higher firing quality as well as a complete and complete chemical reduction of the vessels. Practical comparison of the reconstructed samples showed complete conformity of their characteristics with the ancient specimens (Pisa Tepe, Tushmalan Tepe and Ahmadabad Tepe) and also revealed the secret of producing these two species of gray pottery.

Introduction
In modern archeology, the scientific question is not what we know, but how we know it. This point of view is one of the most important and at the same time the simplest modern archeological approach to past phenomena (Alizadeh, 2004: 91). Therefore, the idea of reconstructing the conditions and the environment in analogy with what was reported in the reports and data was presented. In response to such ambiguities, it can be said that using more modern methods in research such as “experimental archeology” will increase the accuracy of the premises. Early sections of this study have followed up on existing data and library studies of past sources and reports; therefore, in the next section, reconstructing the conditions and environment consistent with the information provided, has been the author’s main goal. In this section, the “kiln making” and the experience of firing the pottery in these kilns were practically achieved, leading to new information on the evolution of the gray pottery production; Proved the assumptions to be true, so that by producing products that were quite similar to ancient data, the key role of the resuscitation process in the firing process and the important role of kiln design and structure in the specific type of firing were demonstrated However, in some sources (Majidzadeh, 1370: 9-7), general references to the reasons for the pottery being grayed out as interfering with elements such as oxygen, iron, and carbon, and in other research, the reduction process was the main reason ( Kambakhshfard, 2010: 296). Finally, it can be added that according to the comparisons and studies of the samples, the firing of the Iron Age gray pottery somehow evolved into conscious firing methods during the first millennium BC. Although in the early Bronze Age achieved to somehow the technique of reduction firing, but only in Iron Age pottery assembladges, the correct pottery reduction firing can be clearly seen.

Discussion 
After the pottery kiln reconstruction operation and the success of the production of the specimens, only by a very simple comparison, the accuracy of the existing probabilities, which were the unknowns of the equation, can be easily ascertained; however, accurate and scientific recordings of the work confirmed these results. Based on these empirical findings for the Bronze Age gray pottery, although previous findings indicate that the potter accessed the firing process may be regenerated, it is due to the amount of carbon accumulated in the samples (carbonization) that is due to its proximity to heavy smoke and firewood. It can be said it was still not possible to control precisely the firing conditions by the potters.
According to existing reports and objective observations of the Bronze Age pottery assemblages, such pottery has much thicker bodies than the gray Iron Age pottery, and empirical indications indicate lower firing temperatures; There are some other features that have been ignored because of their relevance to the subject of this study, that is, firing techniques. As for its firing technique, most of the existing documents refer to the possibility of a ditched type kilns, which is not far-fetched from the evidence.
Reconstruction of the firing conditions of the Bronze Age pottery indicated that the kiln was probably a small-size oven shaped hole that provided a relatively primitive chamber for controlling fire and firing in the vicinity of heavy smoke from firewood and fuel. Reconstructed furnace firing sector were able to provide similar conditions for oven-kilns. In this oven shape kiln, pottery was quite similar to the Bronze Age specimens, especially the Yaniqe or Godin IV pottery, but due to physical limitations and initial quality and reduction facilities, they were never comparable to those found in the Iron Age.
In fact, despite efforts to create optimum conditions, these types of kilns are not capable of achieving a higher quality product such as gray ceramics of the Iron Age, even though due to the excessive energy loss of the maximum heat produced in the oven by about 700 Centigrade did not exceed that production of higher quality pottery in these conditions is almost unlikely.
As the kiln construction techniques expands and evolves, the reconstituted kiln will eventually move closer to the plan of the kilns in the Iron Age, and after a complete overhaul, the result also confirms this claim. In this kiln, reasons such as the separation of the firing chamber, the dominance of proper flame allocation to the vessels, the closure of the pipes and the non-collision of the pipes with the air, made it easier to obtain the appropriate chemical reduction conditions.
In fact, the gray color of the potteries reconstituted with the conditions of the Iron Age kilns are mostly due to the correct reduction and dependence of the carbon chemical interactions and the consumption and replacement of the oxygen present in the composite iron oxide in the ceramic body soil. The technical differences in these two species, which are mainly due to differences in the structure of the kiln structure, are evident in the firing quality of the bodies and the difference in the intensity of carbon accumulation and the color difference between the surface and the body depth.

Conclusion 
After examining the documentation available in the time and location of interested research subject, it can be said that the gray pottery has two major variations, both of which have significant differences in terms of time of occurrence, originating culture, and specific production and reduction techniques. In terms of firing technique characteristics, it can be said that the only similarity between these two cultural products is the presence of a “different gray color” in the body of both types of pottery, which has brought them closer together because of the differences in the characteristics of the other species.
The characteristics of the Early Bronze Age gray pottery that distinguishes it from the Iron Age gray pottery lie in the presence of two main factors, namely the type of kilns and the pottery body features. According to the comparison and examination of samples, firing gray pottery assembladges of the Iron Age somehow evolves conscious firing methods and only in the examples of the Iron Age pottery can a complete and correct chemical reduction of a pottery be clearly seen.
In fact, both of these types of potteries are common in creating an atmosphere of chemical reduction in firing, both of which are interesting in their quality and type of performance, which can be attributed to the progressive evolution of the kiln structure and the facilities and knowledge necessary for its construction and observance for centuries.

Abstract
The 4th millennium BC is one of the most important periods of the history. During the 4th millennium BC, the first urban societies were established in southern Mesopotamia and south-western Iran. Even southern Mesopotamia and southwestern Iran are among central regions of urbanization, but adjacent areas, particularly Central Zagros in western Iran, have played the main role in this process. Godin Tepe is one of the most important archaeological sites during the 4th millennium BC in western Iran which has main role in the urbanization studies. The excavation of this site and Seh Gabi in Kangavar shaped the cultural sequence of Central Zagros until now.  Even this site has close cultural interaction with northern region such as Urmia basin during 5th millennium BC, but later in the 4th millennium BC, this interaction has changed from north to east and to the Central Plateau. The most significant characteristics of the interactions between Godin and the Central Plateau, is some fair painted buff pottery (Godin VI painted pottery) which is reported from the late chalcolithic period sites of the Central plateau (Sialk III6-7b). Regarding the existence  of this painted pottery throughout chalcolithic period ( not only late chalcolithic) in the Central plateau and the absence of this ware in preceding  period(Godin VII) in Godin sequence, it should be noted that the Godin VI painted buff ware is not local in Kangavar area. It has a foreign provenance that should be looked after in Central Plateau. Our methodology in this paper is comparison of this fine painted buff pottery from Godin VI period with the previous coarse ware of Godin VII, and with same ware of late chalcolithic period sites of the Central plateau.  We do not believe in immigration hypothesis about this intrusive ware in Godin sequence. Obviously future studies will be needed.

Introduction
The 4th millennium BC is one of the most important periods of the history? During the 4th millennium BC, the first urban societies were established in southern Mesopotamia and south-western Iran. Even southern Mesopotamia and southwestern Iran are among central regions of urbanization, but adjacent areas, particularly Central Zagros in western Iran, have played the main role in this process. Godin Tepe is one of the most important archaeological sites during the 4th millennium BC in western Iran which has main role in the urbanization studies. The excavation of this site and Seh Gabi in Kangavar shaped the cultural sequence of Central Zagros until now. The focus of our studies is on Godin VII-VI strata which overlapped somewhat with Uruk period in Mesopotamia.  About this period and particularly those well-known Godin V rounded building, many papers were published. Our goal is to study the buff painted pottery of period VI (VI1).  Comparing to the previous period (Godin VII) characterized by coarse and plain chaff tempered pottery, the fine wheel made pottery of period VI is an intrusive one. Noted that the same painted buff pottery was reported from the late chalcolithic period sites of Central plateau, Sialk III6-7b and Ghabristan IV (Fazeli et al 2013, Majidzadeh 1978, 1981). In contrast to Central Zagros where this buff painted pottery was introduced in period VI abruptly, in Central Plateau this pained ware was reported from the previous period (Sialk II-III). Also the Central plateau wares have more divers shape and motif comparing to the Central Zagros so our evidence showing that the original provenance of this painted pottery is in the Central plateau and not in Central Zagros. Noted that east of central Zagros and Central Plateau of Iran during the fourth millennium BC had a great interaction with each other that as a result such painted pottery was developed from the Central plateau to Kangavar.  
Question, Research Method: As mentioned, the focus of this paper is on the fourth millennium BC and on the chalcolithic period strata of Tepe Godin and particularly Godin VI painted buff pottery (Levine and Young 1987, Young 2004, Rothman and Badler 2011, Moghaddam and Javanmardzadeh 2012, Wiess and Young 1975, Young 1969, Young and Levine 1974, Badler 1995, Mattews 2006). Godin tepe reached its maximum level of social complexity in the fourth millennium BC and has great interaction with neighboring areas and particularly the Central plateau of Iran.
 This painted buff pottery is reported from the late chalcolithic period sites of the Central plateau of Iran. Our methodology in this paper is comparison of this fine painted buff pottery from Godin VI period with the previous coarse ware of Godin VII,and with same ware of late chalcolithic period sites of the Central plateau. Introducing this painted pottery in the Godin sequence abruptly, the occurrence of this ware not only in late chalcolithic period sites of Central Plateau but throughout the chalcolithic period and diverse shape and decoration of this ware in chalcolithic period sites of Central Plateau, demonstrated that this ware is related to the  Central Plateau. It was considered as an intrusive ware in the eastern Central Zagros area such as Godin Tepe. Godin Tepe has solid cultural interaction with neighboring areas during the prehistory. During the middle chalcolithic period, this interaction was toward the north and particularly the lake Urmia basin. But in 4th Millennium BC this interaction was changed from north to east and to the Central Plateau.(Roustaie and Azadi 2017). This painted buff pottery is considered as a main evidence of this interaction. Future studies will tell us more about the eastern Central Zagros- Central Plateau interaction.

Conclusion
Introducing this painted pottery in the Godin sequence abruptly, the occurrence of this ware not only in late chalcolithic period sites of Central Plateau but throughout the chalcolithic period and diverse shape and decoration of this ware in chalcolithic period sites of Central Plateau, demonstrated that this ware is related to the  Central Plateau. It was considered as an intrusive ware in the eastern Central Zagros area such as Godin Tepe. The main question regarding this fine painted pottery is about the sudden emergence of this pottery in the sequence of Godin and how it developed from the central Plateau and reached the eastern Central Zagros in the west of Iran?    
 We do not believe in immigration hypothesis about this intrusive ware in Godin sequence as those theory explained for Godin VII Plume ware at Central plateau. As noted at fourth millennium BC, Godin tepe at west of Iran reached its maximum level of social complexity and is one of the most important trade centers which has great contact and interaction with neighboring areas and particularly the Central plateau of Iran. This trend was started at Godin VII period and those plume wares of Zagros were reported from the Central plateau of Iran. noted that before Godin VII period and during the fifth and sixth millennium BC, west of Iran had great interactions and contact with the northwest of Iran. With the beginning of Godin VII period and specially Godin VI period, the direction of communication was changed from north to the east and the areas like the Central plateau become the main commercial partner of the western Iran at fourth millennium BC. Consequently, this fine painted ceramic was evidence of this interactions and communications.  Obviously future studies and excavations will tell more about this fine painted ware in western Iran.

Abstract
In The studying of the settlement layout of an area, the environment and its contexts landscape is considered. most attention is toward to natural Geography and humans relations to locations and living in geographical region. The archaeological and geographical data, is used to analysis of settlement patterns of Bacun communities in the high Zagros. So, the main research questions is to: What factors impacted on the Location Patterns of the High zagros′s Bacun Sites? How is impacts of this Factors on the site numbers? There For, By considering of applicable nature of the subjects and the research mettods. The authors by plaing of theoretical  fram includs of theoretical basis and site visit, will be to study of survey and Excavation evidences. In total the bacon site numbers are 106 in this region. The main factors such as ASL-(altitude of sea level). Site distance to roads and waters water sources, accessibility to agriculture lands vegetation Types, Slope and its directions is considered as independent, and, Bacun site areas as Dependent variable. the relationship of variables are 1 to -1 in the correlation coefficient. the high correlation is showed by closeness to +1, and lowe correlation indicated by closeness to. If the correlation is -1, so the result is convers. The results shows that the variables such as site distance to roads, water supply and land use taype is more important than other variables in the formation of Bacun Sites.

Introduction
Always, the choice of settlementlocations depend to a large extent on environmental characteristics. In studying the arrangement of settlements in an area, the role of the environment and its contexts in a geographical landscape is important (Rostaei, 2010: 8). In this regard, one of the main goals of archaeological activities is to study how the interaction between human societies and environmental diversity, which ultimately led to habitation and location. Important environmental variables affect the location, distribution, sphere of influence, physical development and appearance of human settlements- (Dark, 1995: 134). Therefore, in spatial analysis, since “Landscape” represents the area of human interaction with the environment, the relationship between location and environmental characteristics is considered¬(Clarke, 1976: 119). In fact, by understanding the geographical space, the capacities and potentials present in the area have influenced the new type of settlement (migration, sedentism, or a combination of both). The high Zagros region, which overlaps the current political borders of Chaharmahal and Bakhtiari province, is a defined area that we live in because of our habitat. The High Zagros, in fact, includes the highest part of the Zagros Mountains, and for this reason, it is called “High Zagros”(Darvishzadeh, 1991:175). This region is mountainous and about 76% of it is made up of mountains and hills; While only 24% of it consists of alluvial plains and valleys (Heidari et al, 2014:4). Leading research on this area, which has long been considered as a suitable place for nomadic communities, farmers and pastorals have always been considered by human communities:
The Main Questions Are: What factors impacted on the Location Patterns of the High zagros′s Bacun Sites? How is impacts of this Factors on the site numbers?
Research Method: In this regard, according to the practical nature of the subject and the studied components of the research method, after the theoretical design of the subject, which included reviewing the theoretical foundations and selecting and visiting the sites, to study the documents obtained from the studies and explore archaeological excavations were carried out.

Archaeological Evidence of Bacun Culture in the High Zagros
Due to the fact that most of the archeological activities in the high Zagros region have been focused on the survey; as a result, most of the data and documents are related to potteries. A total of 420 potterysherdsrelated to the Bacun period were identified and studied. Buffswares tempered by sand and fine sand are common, both wheelmade and handmade. This pottery is often in the form of a bowl with a circular bottom and has embellished ornaments with a compositional pattern in the form of wide stripes, circles patterned with dots around it, rounded lines, square textures, and ornaments. Intersecting with the lattice pattern and motif of the sun disk, they are black in color. These include one to three horizontal sections, half or a large section of the container.

Relation and Distribution of Sites to Environmental Variables
The study area has an undeniable role due to its special strategic location in the path of the well-known cultures of central and southern Zagros and their connection with both their position and role. These factors, along with the perspective of the region, play an effective role in creating the tissues of establishment in any period of time. On this basis, human societies have developed adaptive strategies in the habitat of various ecosystems. It is clear that the climate of the area under study is cold and humid with a variety of calcareous and shallow soils that are not so suitable for agriculture. These environmental and biological conditions prevailing in the region have led to the formation of a nomadic livelihood based on traditional livestock and agriculture. Unlike farmers, settlers whose location depends on livestock are not dependent on specific locations or environmental factors. They set up their own camps in places that, in addition to their own safety and that of livestock (against the sedents and predatory animals), had enough pastures for grazing. This new way of life has long been practiced in the highlands, and the area has been used seasonally by nomads. One of the most important shreds of evidence for proving this issue is the low correlation between environmental factors and areas, which indicates that the areas under consideration should be taken into light of the consideration. In the evaluation and study of settlements, altitude, distance, or proximity of sites to communication routes and water resources, the possibility of access to arable land, type of vegetation, slope, and slope direction are considered as independent variables, and the area of Bacun region as the dependent variables. Examining this number of sites, it was concluded that the altitude of 2000 to 2500 meters above sea level has been one of the most suitable elevations for the settlements of the Bacun Zagros; Because these heights have more fertile pastures than areas with lower altitudes at which, there is more evidence of migration in the area. It is clear that slopes less than 15 degrees are suitable for agricultural activities, and lands that have a high slope are in the form of pastures that are not usable for agriculture. This factor indicates that most of the ancient sites, which are located on higher slopes and have a relatively steep slope, did not matter to their inhabitants. This factor, along with the large distribution of cultural findings over a large area, indicates the temporary and seasonal use of these places, which can be related to nomadic communities. In addition, the slope direction factor indicates that no specific direction has been used. It seems that the use of different slope directions indicates temporary residences that have been used for nomads in the summer and the proper slope for their settlement has not been very important. The water and road factor indicates that most areas are close to water sources and roads. The study of land-use variables also shows that lands with poorer vegetation are smaller areas and vice versa. Even today, the distribution of villages is directly related to the type of uses. However, based on a superficial review, it is not possible to comment definitively in this regard, and more evidence is needed. However, it is understood that human beings in this region have long been dependent on places that can, in addition to suitable pasture, also provide the possibility of hunting or gathering food. 

Conclusion
High Zagros in different prehistoric and historic periods due to its strategic positioning and being located in the route of known cultures in central and southern Bacun, and the role of their relationship together,  enjoys an undeniable role and situation. These factors, together with the perspective of the region, play an effective role in creating the tissues of establishment in any period of time. On this basis, human societies have adaptive strategies in various bios. It is clear that the climate of the study area is cold and humid with a variety of calcareous and shallow soils that are not desirable for agriculture. These environmental and biological conditions throughout the region have led to the formation of a nomadic lifestyle based on a limited version of traditional livestock and agriculture. Unlike farmers, nomads, whose location depends on livestock, are not dependent on specific locations or environmental factors. They set up their own camps in places that, in addition to their own safety and that of livestock (against the sedents and predatory animals), had enough pastures for grazing. This type of lifestyle had existed from Bacun period in High Zagros and has been used by nomads in a seasonal manner. Among the most important documents to prove this, is the low correlation between environmental factors and landscaping that indicates that the areas under study have been used for short-term deployment. According to Pearson correlation analysis, the distribution of settlements in the study area in Bacun period, there is a relatively positive correlation between water sources, roads, and the function of the lands but this correlation is mediocre while in regression studies, other factors such as slope and distance to communication paths were also effective with low and medium effect. It is noteworthy that the intensity of the influence of these factors in relation to the Bacun periods of the high Zagros area using multiple linear regression analyzes is equal to 0.336. This number also strongly expresses the correlation between the set of environmental factors and the area of the sites. The results of the correlation and regression coefficients indicate that the distribution of the studied habitats is regulated in relation to the capabilities and constraints of the ecosystem, but its effects are limited.

Abstract
Most of our knowledge on the Palaeolithic of the Iranian Plateau derives from a scientific focus on the area of the Zagros Mountains. In recent years, several Palaeolithic research projects have been conducted in different parts of Iran, including southern piedmonts of the Alborz Mountains and the Iranian Central Plateau. The present paper is an introduction to the archaeological pieces of evidence of a Palaeolithic occupation on the southern slopes of the Alborz Mountains. Sorheh Rockshelter is the first site among a cluster of 8 caves and rock shelters located around 80 km northwest of Tehran. The Palaeolithic artifacts have been recovered from at least three looters’ pits at the center of the rock shelter. Sorheh is significant at least for two aspects: firstly, since the southern slopes of the Alborz Mountains have not yet been identified for the Palaeolithic, the site provides unique data on the Iranian Plateau. Secondly, the site’s location and the physiogeographic and lithic analyses of Sorheh are invaluable for the reconstruction of hominin behavior and settlement patterns in this under-researched area.

Introduction
Compared to the wealth of Palaeolithic data from the Zagros region, the piedmonts of the Alborz Mountains have received little scientific attention. The focus has been on the northern slopes, although the intermountain valleys of the southern Alborz Mountains could have been biogeographically suitable for hunter-gatherers. Since the first systematic efforts of the Palaeolithic research in the Alborz Mountains by Carlton Coon in 1949 (1951, 1957), a few Palaeolithic sites have been discovered in the northern and southern slopes of the Alborz Mountains. Moving from the southern slopes of the Alborz Mountains towards the center of the Iranian Plateau, the number of Palaeolithic sites increases. Especially in recent years, many critical Palaeolithic localities have been identified on the interior plains of the Central Iranian Plateau (Biglari 2003, Masoumi et al. 2010, Eskandari et al. 2010, Vahdati Nasab and Feyz 2014, Vahdati Nasab et al. 2009, 2013, 2014, 2016, Heydari-Guran and Ghasidian 2011, Heydari-Guran et al. 2015, Kaboli 1999).
From the physio-geographical point of view, it seems that the sites located on the southern slopes of Alborz Mountain are related to the inner parts of the Central Iranian Plateau (Heydari-Guran et al., 2015). However, it has always been questioned whether the southern slopes of Alborz, like the northern slopes, were an area of human presence during the Palaeolithic. If so, was there a connection between the inhabitants of the southern and northern Alborz slopes? What about the connections to the inhabitants of the interior plains of the Iranian Plateau? Such questions led the authors to study the valleys located in the Southern Alborz Mountain foothills around 80 km crow flies to Tehran’s northwest. The survey in this region has led to the discovery of a complex of caves and rock shelters. The lithic artifacts from one site, Sorheh Rockshelter, presents new insights into the study of human settlement and behavior during the Late Pleistocene in the Iranian Plateau. 

Sorheh in the Palaeolithic Context of the Iranian Plateau
The Sorheh complex consists of 6 caves, and rock shelters were firstly identified in 2018 by one of the authors (H.H.). The complex is formed in a deep drainage system within tuff, shale, and sandstone lithology along the Senj River. It is located around 19 km north of the modern city of Karaj, at a longitude of 50,957,183 and latitude of 35,992,211, and approximately 1900 m above sea level. The first site of this complex on the west side of the valley, Sorheh Rockshelter, revealed rich Palaeolithic depositions. Preliminary examining the exposed strata and accumulated soil confirmed that the site is rich in archaeological remains.
Five other shelters of the Sorheh complex are located between 20 and 70 m east of Sorheh Rockshelter. They mostly consist of a rocky surface with poor deposition; some were destroyed by the looters’ pits. The bedrock dip in two rock-shelters is towards the front slope caused no preservation of archaeological deposits. The last shelter of this complex is attached to the Senj River and is endangered by periodically river flooding, thus empty of archaeological deposits. The newly-constructed road between the villages of Baraghan at the west to Vamkouh at the east destroyed partly two rock shelters; however, it provided easier access to Sorheh Rockshelter.
In general, the lithic techno-typological characteristics of Sorheh presents significant Middle Palaeolithic elements. These lithic artifacts bear little resemblance to their counterparts from Zagros, such as Warwasi, Bisetun, and Kunji (Dibble and Holdaway 1993, Dibble 1984, Baumler and Speth, 1993). However, a comparison with Zagros sites is not plausible because of the considerable distance between these sites and the Alborz. The sites located in the interior regions of the Iranian Plateau, perhaps, provide more relevant information. Most of the Central Plateau open-air sites, including Chah-e Jam, Mirak, Zaviyeh, and Holabad, are flake-oriented, and Levallois technology has widely been used (Heydari-Guran and Ghasidian 2011, Heydari-Guran et al. 2015, Vahdati Nasab et al. 2013, Vahdati Nasab and Hashemi 2016). Levallois technology was observed abundantly among Sorheh collection, though heavily retouched tools, reminiscent of the Zagros Mousterian, are nearly absent.  
Sorheh’s collection reveals more similarities to two open-air sites of Moghanak and Otchounak. The lithic artifacts from these sites are mostly based on the production of blades and elongated flakes (Berillon et al. 2007). The Levallois technology was broadly practiced in Moghanak and Otchounak. The points from Moghanak are plain and unretouched, reminiscent of the Sorheh points. Due to the lack of characteristic retouched tools in Moghanak and Otchounak, no typological comparisons were possible.

Conclusion
The evidence from Sorheh, Zagros Mountains, and the Iranian Central Plateau indicate various subsistence strategies in different geographical regions. This issue put forward the idea of cultural variability among the Middle Palaeolithic populations (Heydari-Guran et al., 2015) in contrast to the notion of cultural homogeneity (Mousterian) throughout the Iranian Plateau (Rosenberg 1988, Biglari et al. 2009, Piperno 1972). 
Considering the high elevation of 1900 m asl., Sorheh Rockshelter, after Ghaleh Kurd with 2100 m asl., is one of the highest-elevated Palaeolithic sites on the Iranian Plateau. Ghaleh Kurd has revealed Middle Palaeolithic artifacts assigned to the Mousterian techno-complex (Soleimani and Alibeigi 2012). The study of the deposits from Sorheh will provide valuable information on the climatic changes during MIS 5 to 3 up to Holocene. It seems that the area, despite high altitude, periodically provided ideal settlement conditions. Climatic amelioration intervals made the region suitable for settlement. Therefore, the detailed physiogeographic study of the Sorheh complex may provide a wealth of information on late Pleistocene climate changes.
Due to the techno-typological similarities of Sorheh lithics to the sites in the Central Iranian Plateau (Vahdati Nasab et al. 2013, Heydari-Guran et al., 2015), we hypothesize the cultural exchange between late Pleistocene hunter-gatherers of Alborz and the interior parts of the Central Plateau during climatic deterioration periods. 
The discovery of this complex with a particular geographical location in a valley with difficult access and, most importantly, the rich Palaeolithic depositions is an essential step towards answering questions related to the human dispersal at the edge of the Iranian Plateau during Marine Isotope Stages of 5 to 3 stages.
Systematic excavation and acquisition of more data in Sorheh will allow more accurate and detailed comparisons to other Middle Palaeolithic sites of the Iranian Plateau.

Abstract
The Chalcolithic Age is one of the most important prehistoric periods in Iran. The transformations of this period in the Central Zagros have emerged in continuation of the Neolithic period.  One of the important areas of Central Zagros, which had many settlements related to the Chalcolithic era, is Silakhor plain in the north of Lorestan. Despite the cultural richness of the Silakhor plain during the Chalcolithic Age, no purposeful study has been conducted to clarify the Chalcolithic status of this area. In this regard, in order to clarify the settlement models of the Chalcolithic era of Silakhor plain, this study is presented, which is a summary of Ahmad Parviz’s archaeological studies and purposeful studies by the researchers, In the present study, the authors have tried to find the answer to the following questions: What were the settlement models of Silakhor plain in the Chalcolithic era? How can the changes of settlement models in the old, middle and new periods of the Chalcolithic era of Silakhor plain be analyzed? It seems that several factors including water resources, altitude of Silakhor plain and state’s roads have been effective in the formation of settlements in this area during the Chalcolithic age. Studies conducted in this plain so far have shown 80 ancient sites related to the Copper Stone Age. Some of these sites involve all three periods of old, middle and new Chalcolithic era. The spatial data collected in this research have been studied by GIS science studies method and implemented in ArcGIS 10.3 software. The basis of these studies is the distance of each settlement area from the nearest river and its altitude level from Silakhor plain. These maps have been implemented in all three periods of old, middle and new Chalcolithic Age of Silakhor plain.

Introduction
The Chalcolithic Age (mid-fifth millennium to late fourth millennium BC) is one of the prehistoric periods which has witnessed important transformations such as population growth, enhancement of the quality of pottery, the use of copper metal, improvements in the quality of settlement construction and so on.  Some scholars consider this period to be a continuation of Neolithic transformations and some consider it as being independent of other periods. Archaeological studies conducted over the past few decades in the Central Zagros region have shown that this area has seen an increase in population during the Chalcolithic period. This increase in population is inferred from the number of archaeological sites recorded in this period compared to the previous period (Neolithic). Of course, the studies indicate that archaeological studies conducted in connection with the Chalcolithic Age of the Central Zagros, have focused mainly on the Gamasiab River Basin.
Silakhor plain has a suitable situation geographically and climatically.  The flat plain and fertile soil along with sufficient water resources have caused us to see a large number of ancient sites from the Neolithic period to recent centuries. Despite the conducted studies, so far no purposeful studies have been conducted to analyze the residential and settlement situation of the Chalcolitic era of Silakhor plain. In this regard, the researchers, while exploring the studies conducted in this plain, have re-examined the ancient sites of the Chalcolithic era of this plain. Since the area of Silakhor plain is located in Boroujerd and Doroud counties and covers a large part of the north of Lorestan province, in this research, this plain is divided into two parts, north and south, the northern part of which is in Boroujerd and the southern part is in Dorud city. In order to study the situation of the settlements of Silakhor plain more accurately, its northern part in Boroujerd city has been chosen. 

Findings
The chronology of the Chalcolithic age of Silakhor plain and the east of Lorestan is also influenced by the chronology of the Gamasiab river basin and the Kangavar valley. The study and identification of the archaeological and historical monuments of this area has been done recently by Ahmad Parviz in 2006 and the review of the researchers in line with this research has been done in 2016.  In this study, according to Godin chronology, areas related to the chalcolithic age during three periods of old, middle and new era are studied. Sites are evaluated by the ArcGIS 10.3 software after being located on elevation maps through their Universal transverse Mercator (UTM).  In this evaluation, the altitudes of the area compared to the average altitude of the northern half of Silakhor plain and also their distance to the nearest rive, are examined. In the studies performed, it has been determined that 80 sites are belonged to the Chalcolithic age of the northern half of Silakhor plain, some of which include all three periods of old, middle and new Chalcolithic era.
 Of all 80 Chalcolithic Age sites in the study area, 25 sites are related to the old period. These areas are mainly distributed in the central parts and in the plains.  Most sites are at altitudes between 1,500 and 1,600 meters above the sea level.
Of the 80 Chalcolithic Age sites in the study area, 31 sites are related to the Cenozoic Ages. These sites, like the old period, are mainly distributed in the central parts and in the plains. Most sites are at altitudes between 1,500 and 1,600 meters above the sea level.
Of the 80 Chalcolithic Age sites in the study area, 42 are related to the Cenozoic period. These areas, like the old and middle periods of the Chalcolithic Age, are mainly distributed in the central parts and in the plains. Most sites are at altitudes between 1500 and 1600 meters above the sea level.

Conclusion
In this study, it was found that the number of old, middle and new sites of the Chalcolithic Age in the northern half of Silakhor plain (Boroujerd) are 25, 31 and 42 , respectively. This indicates that the Copper Stone Age in this area has developed in a growing trend (in terms of the number of settlement sites). Increasing the number of settlements in this area paves the way for future transformations in the next period (Bronze Age).  Therefore, the beginning of urbanization in this area has had a strong and evolving introduction to the Chalcolithic era.
On one hand, the study of maps prepared in ArcGIS software shows that the vast majority of sites in all three periods in the Chalcolithic Age are located at an altitude of 1500 to 1600 meters (average height of Silakhor plain is 1500 to 1600 meters) and in the area of Silakhor plain.  On the other hand, the analysis of the distribution map of the Chalcolithic sites of this area shows that the settlements of this period have been formed depended on the water resources (rivers).

Abstract
Miankouh Area is contractually known as a district of southern part of the Central Zagros in the southwest of Iran. Despite its small area (680 km2), due to its location between highlands there are two distinct micro ecozones with natural resources and an abundance of plant and animal species and has been suitable for the vertical seasonal movements throughout the year in order to access to various resources in the subsistence from the Pleistocene to the present. Our knowledge of its Mousterian cultures is derived from three-season field surveys between 2009 and 2011 years in both Low Altitude (LAZ) and High Altitude Zones (HAZ) with an average altitude of 1510 and 2601 meters above sea level (m.a.s.l). This paper seeks to answer (1) what is the position of Miankouh’s MP cultures among the well-known Mousterian cultures in the Zagros Mountains of Iran? And (2) what is the radius of movement of MP hunter-gatherers of in the landscape of Miankouh through the study of the stone assemblage of both LAZ and HAZ? Totally, 1454 stone artifacts were collected from the Middle Paleolithic Open-air sites of both zones. Preliminary results show that the MP hunter-gatherers of Miankouh exploited both zones with relatively a homogeneous tool kit influenced by the permanent rivers in LAZ and pool resources available in HAZ within the daily radius of movement at a distance of 5 to 20 km, which had often been turned into flakes and various tools using several techniques. They also used the type of tools that are commonly recognizable in the stone industries of other MP cultures of Zagros.

Introduction
One of the largest bodies of research on montane adaptation comes from the Zagros Mountains of Iran and Iraq. Most of the Palaeolithic archaeological researches of Zagros have focused on, north, south (Azadi, 2017; Dashtizadeh & Hosseini, 2008; Conard et al., 2006; Rosenberg, 1985) as well as the north parts of Central Zagros (see Abdi, 1999; Adams, 1954; Biglari & Abdi, 1999; Coon, 1951; Dibble, 1984; Jaubert et al., 2009; Trinkaus & Biglari, 2006; Young & Smith, 1966; Roustaei et al., 2002; Roustaei et al., 2004). Broadly, it can be declared that there is no comprehensive evidence about conditions of the Palaeolithic sites in the Bakhtiari region in Southern part of the central Zagros.
This paper presents an analysis of a group of MP lithic assemblages collected from a set of open-air localities during field surveys conducted in both Lower Altitude (LAZ) and Higher Altitude Zones (HAZ) of Miankouh District with an area of approximately 680 km2 and an average elevation of 1510 and 2601 meters above sea level (m.a.s.l) in Chaharmahal and Bakhtiari (ChB) Province, Iran (Khosrowzadeh, 2011, 2010a, 2009).
For the aims, these assemblages provide insights into mobility, landscape-use, and lithic technological decision-making in high-altitude environments by the MP hunter-gatherers in the Zagros Mountains and beyond.
These data presented in the current paper originates from the area of the Miankouh highlands (Bahraminia et al., 2022) from where MP evidence can help further elucidate the issues identified with the Zagros Mousterian as an explanatory framework for MP seasonal mobility and land-use patterns in the Zagros Mountains (Lindly, 1997; Skinner, 1965).
This paper seeks to answer (1) what is the position of Miankouh’s MP cultures among the well-known Mousterian cultures in the Zagros Mountains of Iran? And (2) what is the radius of movement of MP hunter-gatherers of in the landscape of Miankouh through the study of the stone assemblage of both LAZ and HAZ?

Materials and Methods
To record the surface findings, as soon as the first artefact was found, a radius of 200 meters around the point of this find was evaluated in different directions by a group of five people. By focusing on the MP period, 177 MPO locales in the form of points with XY coordinates incorporating 1454 stone artefact were analyzed. In order to assess the techno-typological aspects of the lithic assemblages in the region we used advanced analytical tools (SPSS tool boxes) at the local landscape level. 

Results
From the surface of both ecozones a low density of lithic artefacts ranging from 1 to 36 pieces was identified for the MP each identified here as a specific “locale”. The area under study provided a large number of cultural materials including lithic artefacts from MP UP and EP as well as a considerable amount of potteries from the Neolithic, Chalcolithic as well as the Late Islamic period. For the purpose of this paper, we only examined stone assemblage of the MP period. 
A total of 1454 lithic artefacts (whole and fragmented) were collected during the Miankouh survey, with 874 pieces from 113 MPO locales coming from LAZ, and 580 pieces from 63 MPO locales from HAZ. We identified four main groups including core, tool, unretouched flake, and debris.
In terms of lithic technology, preferential and recurrent Levallois methods are clearly used in the production of flakes. Recurrent methods of unipolar, bipolar, and centripetal were used to knap the flakes. Moreover, the dorsal scar patterns among the cores, tools and unretouched flakes indicate non-Levallois semi-pyramidal and discoidal methods are other debitage techniques in the MP stone industry of Miankouh.
For 970 artefacts which were categorized as tool, scrapers and blades represent highest frequency of tool types in assemblage which were followed by retouched flakes, points, notch/denticulates, borer/burins, and hand axes. In process of tool-making have generally been used the Plain/flat and faceted platforms more than other types. Points of both LAZ and HAZ are the end products in this group because about 82 % of them do not have any cortex on their dorsal face. Also, 50.88 % of total unretouched whole flakes have cortex on the dorsal face. Geneste has already classified such samples in the early stages of the reduction system in the tool production cycle (Geneste, 1985). 

Conclusion
The use of Levallois technique was initially reported not to be present in the Mousterian Zagros assemblages (Skinner, 1965). Its widespread use within Zagros Middle Palaeolithic assemblages was however eventually confirmed by Dibble (1984) (Bahraminia et al., 2022) (and papers in Olszewski and Dibble, 1993). That the utilization of Levallois technique in the region cannot however be expected to be universal has recently been established through excavations at Qaleh Bozi close to the Miankouh field survey area, where a relative absence of Levallois technique was reported (Biglari et al., 2009).
Unfortunately, we do not have reliable metric core data and other lithic artefacts from other MP sites of the Zagros in order to support our results. In order to better understand the effects of elevation on size and weight as well as its effect on the quality and quantity of MP toolkits, we need to measure metric values of lithic assemblages from other sites/locales within the Zagros Mountains at different elevations from a ‘landscape-oriented’ or ‘siteless’ approach.
The overall composition of the Miankouh lithic assemblage from a techno-typological point of view includes relatively short flakes. Retouched pieces on flake are other features of this collection. A glance at all cores from Miankouh reveal that in LAZ usually larger stone cobbles have been used as cores in comparison with HAZ. The mean weight of those from LAZ is 56.66 grams while in HAZ it is 41.98. In the case of core reduction strategies, the high frequency of cortical flakes, unretouched flakes, irregular retouched flakes, and typical tools suggest that the knapping processes were accomplished at some of localities of LAZ. It seems that the production of tools on cortical flakes (for example notch/denticulates) has been a common tool making tradition in the study area. The presence of short flakes in the Miankouh lithic assemblage may reflect the fact that the use of short flakes had been a common tradition at the MP sites in high-altitude environments. It can be raised that some Mousterian debitage strategies for the production of flakes and tools were commonly presented in Miankouh where stone raw material in the form of river pebbles and chert nodules of limestone outcrops were available in this mountainous region.

Abstract
The investigation and study of the plains and valleys between the mountains of South Zagros in Iran from a geographical and cultural point of view leads to a deeper understanding of how the archaeological cultures of those regions were formed and expanded; The southern parts of Zagros have their own geographical and cultural areas, while the northern regions include Abadeh, Eghlid, and Semirom; The Ghabr-e Keykha river basins and Semirom region are significant for the study of cultural interactions and areas of expansion of the archaeological cultures of Fars province because of their location at the intersection of the archaeological cultures of South Zagros. Therefore, we started the studies to investigate the prehistoric settlements and demographic fluctuations of the Ghabr-e Keykha river basin and to identify the oldest habitation in the central part of Semirom. The current research was based on a season of the archaeological survey with a habitat analysis approach in the central part of Semirom city (Figure: 1); After preparing the required maps, we surveyed the target area, and random sampling was done. Due to the low environmental capabilities, the sites were not in the dimensions and size of settlements in the central parts of Fars. It has been considered from sources of water and quality soil and living in the closest distance to rivers and reliable sources of water; It is interesting to note that, unlike in the central parts of Fars, there is no evidence of a sharp decrease in the number of enclosures and a change in the lifestyle from a sedentary farmer to a nomadism, and we are witnessing the size of Sites and the increase in population during the Banesh period.

Introduction
Semirom county has an area of about 5224 square kilometers and an average height of 2400 meters above sea level, and its location is in the south of Isfahan province on the slopes of the Zagros highlands. This county is in the middle of South Zagros and the eastern slope of Dena highlands. What turned Semirom County into a distinctive locale in the prehistoric and later periods was its obvious location at the interface of the three major Iranian cultural zones, namely Fars to the south, Bakhtiari to the west, and the central plateau to the north. Thus, the region represents a significant focal point for exploring the cultural interactions of the cited zones. What is evident with regard to the regional archaeological investigations is the lack of systematic surveys, local chronology, excavated sites, and knowledge of the cultural evolutions in prehistoric times.  From another geographical point of view, Semirom lay in the southernmost part of Isfahan, that is the lowermost focal point of the central plateau cultures, wherein the penetration of the Bakun culture cannot be ruled out.
The basic question concerns the circumstances of settlements and population fluctuations at the prehistoric sites in Central District of Semirom, focusing on the factors of settlement size, water resources and arable lands, in particular during the Bronze Age, to determine whether there are comparisons with the central parts of Fars? Another question is: Given the location of the Semirom region at the convergence point of the cultures of the central Fars, are there any evidences of cultural interactions with the latter cultures? Furthermore, since at the current status of our understanding, grounded in the excavations of Tall-e Mash Karim (Sardari and Taheri 2015, 266; Taheri 2015, 233), and Gol-Afshan (Taheri 2009, 345; Taheri, 2020), the region’s earliest occupations date to the Bakun period, we were looking for information about potential earlier Paleolithic and Neolithic settlements. Judging by previous surface surveys, albeit their partial coverage of the region, and excavations, I assumed that the region was under the influence of Fars archaeological cultures, and indications for influences from the Bakhtiari region and the central Iranian plateau are absent. Thus, testing this hypothesis called for carrying out more careful intensive surveys in parts of Semirom.

Discussion
From the Middle Paleolithic period, we identified three open sites, two of which were created on the terraces dominating the rivers, and one site with a long distance from the permanent water resources at the exit of one of the northern valleys of the region is surveyed. Earlier, the settlement in this area was dated to the Bakun period. But it dates back to the Middle Paleolithic period, according to new surveys and evidence of human activities identified from the Paleolithic period. From the Neolithic period, we identified only one site related to the Shams Abad period, but with the beginning of the Bakun period(Chalcolithic), like Fars, we see an increase in settlements from one Neolithic site to seven sites in the Bakun period and four sites in the Lapui period. Various causes can be involved in this increase in population. First, with the warming of the region after the late Holocene, in a way that was not much different from the current climate of the area (Sadat Hosseini et al., 2015), better conditions were provided for the expansion of settlements and human habitation. We can see its appearance at the beginning of the Shams Abad period and the identification of one site. On the other hand, with the revelation of the Bakun culture in the Kur river basin, which had progressed in the economic and social contexts, more possibilities and abilities were obtained to exploit the environment, such as the expansion of irrigation canals began in the Shams Abad era and reached its peak during this period. They used more diverse animals in their food chain through hunting and animal husbandry. Although, like Fars, we see an increase of sites in the Bakun and Lapui periods. it seems that the Semirom region should be introduced as one of the peripheral regions of Fars and influenced by the archaeological cultures of this region with its cultural characteristics, in terms of dimensions and number of sites, livelihood patterns, and pottery motifs. That needs to be studied separately and consider its specific climatic and geographical conditions in the framework of the archaeological cultures of Fars.
 In the Banesh period, the number of sites is reduced to three. It seems that this region, unlike Fars, in this period, not only has not a noticeable decrease in population compared to the Lapui period, but we can see the stability of the population and the size of the sites. Also, observing the beveled rim pottery (Figure: 7) in this region is an important issue that doubles the need for a more detailed study of the entire county in this period. 

Conclusion
The results indicated the influence of environmental factors in the selection of sites, and factors such as distance and proximity to reliable water resources, fertile lands with easier access to water, and a suitable slope were the main factors for choosing a place of habitation. In all prehistoric times, most of the sites were very close to the main branches of the rivers (Map: 3); Most of them have settled in the middle of the plain, where the ground is less steep and has better soil. The reason that we identified no areas in the foothills of the mountains and at a greater distance from the rivers is because of the factors such as more difficult access to water resources due to the greater depth of the valleys in the initial parts, the lack of good soil, and the impossibility of exploiting water resources through canalization. There may be other factors involved which require more research to identify. In this lifestyle, the location should be chosen more carefully because the stay duration was longer, and the soil and water resources use was continuous and planned. In the end, based on the model that most archaeologists use to estimate the population and their interpretations, i.e., determining 100 to 150 people for each hectare in prehistoric periods (Alizadeh, 1392: 159), we predicted a population of over 200 people for the central part of Semirom in the Neolithic period, considering that we identified only one site with an area of 15,000 square meters. After that, during the Bakun period, the total area of seven sites was 27,500 square meters, and the estimated population was about 550 people. In the Lapui period, the total area of all the sites was 18,000 square meters, with an estimated population of about 350 people. In the Banesh period, the total area of all the sites was 50,000 square meters, which reached around 1,000 people with the increase in population. This analysis clearly shows the beginning of the increase of the sites with the beginning of the Shams Abad period. It continues to increase in the Bakun period. In the Lapui period, we are facing a 40% decrease in the number of sites. Again, in the Banesh period, the size of the sites increased a lot, and we estimated the largest population for this period.

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.

The city of Sahneh, located 54 kilometers northeast of Kermanshah in the central Zagros passage, plays a crucial role as a strategic crossroads, linking the Iranian central plateau to Mesopotamia and connecting the internal plains of Kermanshah to Hamadan. Archaeological surveys in Sahneh County, conducted in 2003, employed the site survey method, whereby all ancient sites were studied in terms of their geographical location and settlement sequence. This approach provides the necessary data for interpreting the settlement history of the region. As a result of this field research, for the first time, two archaeological sites containing cultural materials from the Middle Elamite period were identified in this area. This discovery significantly extends the cultural domain of the Middle Elamite period in the Zagros toward the east and northeast, indicating that the influence of this civilization extended beyond its known centers in the southwestern provinces of Iran (such as Khuzestan, Kohgiluyeh and Boyer-Ahmad, Fars, and Bushehr) as far as Kermanshah Province. Given the importance of these findings, further surveys were carried out in 2024 and 2025 to identify Middle Elamite sites in Sahneh. Following this research, two additional sites with Middle Elamite cultural materials were discovered. These findings not only confirm the existence of an active cultural-commercial corridor in this region but also highlight the necessity of revising cultural-geographical maps and historical developments of the Middle Elamite period in the central Zagros. Continued studies and targeted excavations at these sites can clarify the role of this region in the network of cultural interactions between the Iranian Plateau and Mesopotamia and are expected to lead to a fundamental reassessment of current perspectives on the history of this era.
