Fusulinids are among the most important index foraminifera in Upper Paleozoic sediments. The Upper Permian strata are widely distributed in south of Sirjan. The Kavir-kuh section is a suitable outcrops in this region and located ۱۸ k.m of Sirjan. It consists of medium to thick- bedded dark gray limestone. In order to determine faunal assemblage and biozonation of the section, a total of ۱۰۰ thin sections were prepared and studied. Twenty four genera and sixteen species of Permian foraminifera have been identified and also eghit stratigraphical horizons were recognized. Base on index species of foraminifera belong to Schubertellidae, Geinitzinidae, Paleotextularidae, Neoschwagerinidae, Schwagernidae families, the age of  horizons has been determined as Guadalupian to Early Dzhulfian.High diversity and  abudance  of  fusulinids show a   favorable  condition during the deposition of the strata.
