archaeological analysis of early bronze age distributions in northwest of iran

early bronze age (eba) in the middle east is considered to be the dawn of civilization, spread of writing, and proto-urbanism; and mesopotamia was the center of these historical events. cultural material remains at the beginning of this period in this vast area – including western iran, caucasus (also beyond), anatolia, levant and northern mesopotamia – have wonderful similarities in spite of different names (eba, trans-caucasian, yanig culture, kura-arax culture). unluckily, for many reasons archaeological researches focused on this vast area like caucasus separately. for recent three decades there have been numerous surveys and excavations and multi-disciplined studies in western iran. it seems eba culture spreads out to central plateau of iran so that the core of this culture could be arax-urmia-kura basin. presented here are the results of an archaeological analysis on early bronze age from northwest of iran, central zagros, central plateau of iran and borderlands using some scientific information and data such as gis and obsidian provenance studies.
