The Central Plateau of Iran, which has been called by various names until now, has special place in terms of Archaeological developments from the fifth millennium BC to the beginning of the third millennium BC. Archaeological evidence indicates the desolation, destruction, displacement, moving, and formation of sites during that period. Despite the dominance of this situation in the field of settlement, the analysis of pottery data in the first place, followed by architecture, metallurgy, and burial, indicates that there was an ongoing cultural continuity. The sites in the area did not have high sustainablity due to environmental factors. Therefore, the analysis of relevant data based on chaos and complexity theories as well as the general theory indicates that the communities in the region followed a particular pattern from the Transitional Cholcolithic to the Early Bronze Age 1. They would survive with a movement. While the continuity of social life was guaranteed by the abandonment of one site and the formation of a new one, technological, architectural, and economic revolution took place at the new site. It is often observed that this life continuity was accompanied by technological developments and innovations. In fact, the aforementioned societies did not collapse but leaving a site ensured their social and economic life. In the Central Plateau of Iran, we encounter with communities that have pursued the process of endogenous development while at the same time expanding inter-regional communication.

The petrographic analysis of ceramics can often answer a wide variety of archaeological questions, especially regarding fabrication, manufacturing processes which were despite focused on the construction and trade of pottery. However, ceramics which were collected from the same site can mostly differ in their chemistry as well as fabrics. As is applied in many cases, essential archaeological survey and documentations in a theoretical framework are key to the proper application of ceramic petrography through the archaeometrical research. This paper deals with the petrographically approach on Kura-Araxes or Early Bronze Age ceramics manufacturing processes of Sonqor Plain. It is of worth-knowing to contribute that the contact and exchange strategies between indigenous communities and several cultural-spheres during Early Bronze Age (beginning of the fourth millennium BC) in this area. Morphological data along with mineralogical composition of ceramics were applied to determine the major elements of the pottery sherds. Based on the result, one can be suggested that all of sherds are in the same group and were demonstrated mightily local productions. The ceramic manufacturing technology indicates same patterns of material interactions during the ETC or Kura-Araxes in all of the investigated sites in Sonqor Plain.
