Secondly, settlement continued in site from the time of formation Susiana to the urbanization. Third, the study and comparison of the stylistic and technical characteristics of the pottery indicate that the site is in contact with other parts of the periphery of Susiana plain.From the viewpoint of the form and motif of the pottery, the pottery of the New Middle Susiana phase, despite the continuity of some types of pottery, show a number of new types has been continued in the Middle of the New Susiana. On the other hand, the stylistic and technical similarities of the pottery in this phase show close relation to central place of Chogha Mish.This is more likely to be the familiarity and relevance of the inhabitants in the Gach-e Sangi with the people the central area of the plain. At the same time with abandonment of Chogha Mish as a major center on the eastern border of the northern central plain of Khuzestan, the trend towards the west of the settlements developed in Susiana plain, the factor of this event is the threat of sediment flood thrusts by the nomads of the Zagros highlands.So the results of comparative studies of Gach-e Sangi pottery, on the other hand, point to,continuity or changes is not only about the change in the technical or stylistic of the pottery tradition, but also reflects socio-economic transformations.
