Chalcolithic

In March 2004, a fluxgate gradiometer survey was conducted over Tepe Ghabristan, covering approximately 6ha of ground. It identified further areas of the Iron Age cemetery with possible grave pits (Areas B and C). In addition, an irrigation channel was discovered which could be contemporary to these Iron Age graves (Area D). The anomalies in Area E can be interpreted as buried structural remains, possibly linked to metalworking.

The little Zab River in northwestern Iran rises from the mountains Piranshehr and flows from the northwest to the southeast direction to join Iraq from Alan passage. The River basin contains a large number of ancient settlements, and its lower area that is close to the Zab River has been the most interesting place for people in the Neolithic Age. An increasing population during Chalcolithic Age led to the dispersion of settlements. These sites are located in the north of this basin, in a valley and a little plain.

Lorestan’s Balageriveh, is a lowland passage area, located in between two rivers, Dez and Kashkan in South Central Zagros; the area itself is divided into three parts, northern, southern and central. In previous studies in Lorestan, a form of complete shift was depicted from sedentary lifestyle to a mobile one, in transition between the Late Chalcolithic and the Middle Bronze Age. Central Balageriveh is important to be studied on this matter due to its central position among Susiana (Elam), Central Zagros, Bakhtiyari region, Posht Kouh and Mesopotamia, as well as paleoclimatology and archaeological studies conducted over there. Due to the above reasons, the present study has taken into account paleoclimatology and archaeological data, the transition process from Chalcolithic Cultures to the Bronze Age, a change in settlement patterns and the role of socio-economic and environmental changes in this pattern alteration. The findings indicated that long-time climatic change which occurred in the middle of 4th millennium B.C. in the region cannot be regarded as the cause of the complete cultural gap and the change of settlement pattern at the time. Instead, it seems that with the collapse of the Uruk System and its commercial organization, the areas like Balageriveh which were intermediary in this commercial network, lost their charm. When people like Kura-Araxes, on whom some would put the blame of the Uruk collapse as they were mobile pastoralists, settled in some areas which the previous power had lived, the commercial paths withered and Balageriveh’s intermediary role diminished and instead due to socio-political reasons, the lowland characteristics of the area became highlighted and the change in settlement pattern occurred.

Iranian Azarbaijan and the southern Caucasus have relatively good environmental conditions for the formation of ancient settlements. These include the Lake of Urmia and the coasts of Aras in northwestern Iran and the basins of the Kora River, Mill-Moghan (mountainous areas) in the South Caucasus. The archaeological evidences and recent researches in the two geographical areas provide commonalities and cultural similarities of the period. The main purpose of this article is to introduce traditions of pottery and sites and determine the chronological sequence in the study areas. In order to achieve cultural interactions in the studied geographical area in the Chalcolithic period, the following questions are proposed: What is the status of chronological sequence in the two cultural domains? The main hypothesis in this regard is the existence of chronology is almost identical in the two geographical areas. How do the settlement layers and the sequence of habitation from the Neolithic to the Chalcolithic period in ancient sites show the issue of cultural continuity and transmission? The present writing is done by descriptive-analytical method. As a final result, it can be said that similarities and differences of archaeological data, including the features of pottery, architectural structure, burial etc. point out that by studying areas such as Dalma Tepe, Jolfa’s Kul Tepe, Khoy’s Dava Göz, etc. in Northwestern Iran and Leila Tepesi, Qalayeri, Poylu Tepe, etc in the South Caucasus region have been obtained and in terms of chronology, the millennium BC includes 5000 BC to 3700-3600 BC. 

Naderi Tepe is located in the southeast of Mashhad and is located next to a communication route. According to the typology, the wares of this site include the variety of species and the quantity of pottery pieces from the Chalcolithic to the historical period. During the study of this site, based on the obtained wares, 10 pieces of the sherds and two pieces of stone quern were analyzed by petrography and their thin sections were examined in order to find the minerals in them. The purpose of this experiment was to identify the components of each sherd, the difference in composition and materials between samples, determine the percentage of each composition, determine the temperature of pottery firing according to the available minerals, and investigate the origin of the raw materials that make up wares. In the laboratory, a thin section was prepared from the pottery and then studied with an optical microscope. The results of the studies show that the mineralogy of the sherds from the site shows the better quality and purer paste of the sherds produced from the middle Bronze Age to the end of this period, which shows the high skill of the potter in making and knowing the raw materials in the production of pottery. The results of this research can be the basis for the comparison of ware types in terms of construction techniques and compounds used in them in the surrounding areas, especially in the Mashhad Plain.
