Depositional environment and sequence stratigraphy of the Asmari Formation in Kuh-e Asmari and Kuh-e Gurpi surface sections

In this research the sedimentary successions of the Asmari Formation with the age of Oligocene â Miocene in two outcrops of kuhâe Asmari, located in the Dezful embayment with a thickness of 349 m and kuhâe Gurpi (Pabdeh valley), located at the Izeh zone with a thickness of 352m have been studied.
