The Idier was first found at the secon survey campaign in 1383/2004. Idier was excavated 2004 too. Idier is located 16 km south of Aslandouz, in Moghan plain. Aras River and its branches, passing through the Moghan plain, have provided the appropriate environmental conditions for the establishment of human settlements. Suitable soil for sowing, proper humidity, rainfall of approximately 300 mm per year, relatively warm temperatures and low Mogan area, all indicate the great potential of this plain for the cultivation of high quality products, as well as the rich meadows of this plain, conditions for livestock breeders in order to preserve Livestock, in autumn, winter and spring. With these conditions, it seems that the area should have a large number of ancient sites that have been formed in this climate, but because of the extensive construction and leveling of the vast lands of the Moghan Plain with various agencies, organizations, institutions and farmers, these sites have disappeared and only a few. This research is based on the systematic survey of site and stratigraphy excavation. we have tried to answer some of the questions raised along with the typology of pottery. Questions such as how to look at the technological and decorative changes of Idira’ s potteries; The influence of Obaid culture has existed in this area? What is the position of this culture in this area, despite the Dolma culture pottery in Idir’ s findings? What impact does native culture have on clay products? And in the end, it’ s a matter of special interest to the Indigo bronze ware, which has been using its pottery technology in neighboring areas along with its interactions. It can be argued, that the Chalcolithic potteries hier are local, although there are similarities to other northwestern Chalcolithic settlements in Iran.
