Investigation of the Chronological Statue of the Bronze Age in East of Lorestan (Based on the Excavation of the Gariran Tepe)

Eastern Lorestan is one of the regions of the Central Zagros region where the fewest number of chronological studies related to the Bronze Age have been conducted. Chronological studies of the Central Zagros are more concentrated than other areas in the Gamasiab river areas in Nahavand and Kangavar. The chronological framework of Lorestan and Gamasiab valley face many problems concerning the Bronze Age. At present, the chronology of Gamasiab and Kangavar region is related to the 1970 and 1980s and so far, the volume and quality of archaeological findings has changed in this areas. In order to clarrify of the chronological status of East of Lorestan, stratigraphic excavation have been carried out at the mound of Gariran in Aleshtar. Excavations in this area have shown that the common pottery of the Bronze Age after the beginning of the Elamite period is a well-made painted pottery style called Godin III. Meanwhile, in the Gamasiab river basin, the Early Bronze Age is known by the Yaniq style. Based on the excavations at Gariran Tepe, it seems that the common cultures in the Bronze Age of Lorestan were mostly related to the western and southern regions of Lorestan. Yaniq pottery has not been obseved widely in this area. In this study, according to the findings obtained from the excavations at Gariran Tepe, the chronology has been adjusted according to the cultural and regional realities. According to this, the Early Bronze Age (early-to-mid third millennium BCE) has contined without any interruption at Gariran Tepe after the begining of the Elamite period. In this period of pottery, which is common to the old phases of old Godin III (which in Godin’s chronology belongs to the middle period of the Bronze Age) ancient Bronze polychrome pottery. In this study, we have attempted to answer the following questions: What is the chronology of eastern Lorestan during the Bronze Age, and, how can the exploration of Gariran Tepe’s stratigraphy be corrected given the chronological defects of eastern of Lorestan.
