This sedimentary rocks assemblage introduced as Chehelkaman Formation at Kopet-Dagh basin and situated between Pestehligh and Khangiran Formations. The aim of this study is considerate and determination of time and depositional of the Chehelkaman formation in Jowzak section. Based on biostratigraphy studies of these sediments, determinated 8 genus and 16 species of microfossils that shows Middle to Upper Paleocene age. Chehelkaman formation sediments are deposited in a deep parts of basin during a at transgressive cycle. Keyword: Kopet-Dagh, Jowzak, Litostratigraphy, Biostratigraphy, Foraminifera, Paleocene.
