Geoksyur Oasis, located in the foothills of the Kopetdag, to the east of Altyndepe, is in the center of a cluster of tepes in the desert region on the northern Iranian border. It extends over an area of 12 ha. It is  to the east of the city of Tedzhen. Even though in the Aneolithic Period (4th – early 3rd century BC), the space between houses was used for burials, the settlement was not a cemetery but rather a settlement which was affected by shifting sand dunes and scarcity of water. Geoksyr was revealed to contain "adobe multi-room houses and group burial chambers". Ceramics were also found with dichromatic paintings and many female terracotta figurines. The culture of Geoksyurtepe was correlated with an eastern Anau group of tribes linked to Elam and Mesopotamia.
