Abstract
In this research, microbiostratigraphy and depositional environmental implications related to the Surgah Formation at the northern flank of Sepid kuh anticline, Lorestan Basin, is discussed. A study of small planktonic foraminifera from the 101m-thick Surgah Formation led to the identification of three Turonain- Santonian biozones: 1-Helvetoglobotruncana helvitica, 2-Marginotruncana sigali,3-Dicarinella concavata. The age of Surgah Formation in the study area is determined as Turonian- Santonian. The Surgah Formation overlies the Sarvak Formation and underlies Ilam Formation in the studied stratigraphic section. Based on analysis of pelagic foraminiferal assemblages and microfacies features 7 different microfacies have been recognized, which can be grouped into three depositional environments: inner, middle and outer ramp.
