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
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 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
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. 
Keywords: Central Iranian Plateau, Alborz Mountains, West-Central Zagros, Middle Palaeolithic, Levallois.

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

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).
