Abstract: In current research; Talehzangformation of carbonaceous deposits has been studied in theNeqarehsection. In this section; the studied sediments with a thickness of 101.7 meter mainly consist of carbonate rocks and are divided into six sections based on field observations and lithology changes. These deposits could be found continuously and isoclines on the Amiran and lower of Kashkan formations. It should be noted that; in the 1: 100000 map of Khorramabad; these deposits have been mentioned as Tarbur sediments. Fifty four samples have been used from the mentioned section (fifty samples from the Talehzang formation and four samples from the Amiran formation) that; after preparing a thin section of them and microscopic studies; in total; 12 species; 12genus and 1 group of Benthic foraminifers and 1 group of red algae And some macrofossil fragments of echinoderms; Brachiopod and bivalve were identified. By studying benthic foraminifers; in result; 1assemblage zone was identified as a Miscelaneaminuta - Kathinahunti Assemblage zone which is comparable with Assemblagezonenumber 43 of Wyand (1965) with an late Paleocene age (Thanetian).
