Abstract
The biostratigraphy of the Permian Limestone strata in the south of the Sanandaj-Sirjan Metamorphic belt is descried in this research. The Chekenu Section with 381 m thickness is one of the most complete Permin outcrops in Iran that locates at the south of the Sanandaj-Sirjan Metamorphic Belt. Because of the importance of fusulinida in the biostratigraphy of the Permian, just the fusulinida family included in the study that resulted in to the identification of 31 species of them. Based on the paleogeographic position of the Sanandaj-Sirjan Metamorphic belt at the south of the Paleo-Tethys during the Permian, the ranges of the identified fusulinida have compared with suggested biozone for southern realm of the Paleo-Tethys to determine the age of the studied strata. Based on the range of identified Fusulina genera, include Quasifusulina, Mesoschubertella, Chalaroshwagerina, Paraleeina, Armeia, Skinnerella, Cancellin, Chusenella, Eoverbeekina, Presumatrina, Eopolydieoxodina, Afghanella, Schwagerina, Sumatrina, Donbarulaand Palaeofusulina in the studied section and suggested biozone for southern realm of the Paleo-Tethys, the studied deposits are belonged to the Asselian-Julfian (Cissuralian-Lupingian) age.
