So far, much research has been done on the Sassanid period, which is generally related to state centers and large cities of this period, and less attention has been paid to rural or temporary settlements that have been associated with these centers, the administrative, social, economic structures and settlement patterns interpretations requires attention to all of the sites in the region. Tol-e Gap Kenareh is located about ? km from Istakhr city. During the excavations in this area, deposits with Sassanid pottery were identified. Due to the low thickness of the deposits, the lack of architectural identification, the distribution of ash seems that this area was temporary site during the Sassanid period. Current study by introducing a temporary site of the Sassanid period, firstly is focused on the classification and typology of pottery obtained from excavation. to obtain the composition and structure of potteries, differences and similarities between them, kiln temperature, petrographic experiments on ? samples of The pottery was made, which resulted in the fact that all the pottery had a porphyry texture, and due to the presence of calcite in the samples, the temperature of the kiln was probably less than ??? degrees Celsius. Also, by studying the geology of the area and comparing the samples with other samples tested from other periods of the area, it can be said that pottery is indigenous and local production. For absolute dating, two animal bone specimens were tested in a laboratory that suggested date of ??? to ??? AD for the Sasanian period deposits in this site.
