During this Survey, ۱۲ sites from the Bronze Age were identified and recorded, one of its important results is to study the developments that occurred in the Bronze Age and determine the position of the region in the chronological table of southeastern Iran. The main question raised in this research is: Based on cultural materials collected from the Bronze Age sites of Hozdar region, how is the relative chronology and cultural relations of this region with neighboring areas evaluated?
