In this research,microbiostratigraphy and depositional environmental implications related to the Shahbazan Formation at the northern flank of Chenaerh anticline are discussed. Carbonate sequences of the Shahbazan Formation consist mainly of large benthic foraminifera along with other skeletal and non-skeletal components.Two biozones have been recognized by distribution of large foraminifera in the studied area that indicate middle Eocene age( Lutetian).
