        In this research, biostratigraphy related to the carbonate succession of the Shahbazan Formation at the southeastern flank of Chenar anticline, Lurestan Basin, is discussed. A study of large benthic foraminifera from the 294 mthick Shahbazan Formation led to the identification of two Middle Eocene biozones: Somalina sp. Zone, Nummulites-Alveolina Assemblage Zone. The age of the Shahbazan Formation in the study area is determined as Middle Eocene. The Shahbazn Formation overlies the Pabdeh Formation and underlies Asmari Formation in the studied stratigraphic section. The lower part of Asmari Formation is characterized by thick – bedded of limestone, with Nerpherolepidina sp., which reflects deposition during Chattian age. In this study, we introduced a paraconformity between Shabazan and Asmari Formations which is attributed to the PriabonianChattian. Manuscript profile

        This research focusses on the biostratigraphy and paleoecological implications of the carbonatesof the Asmari Formation. The Asmari Formation is located in the Siah Kuhanticline of Izeh, Zagros Basin, SW Iran. It is of Late Oligocene (Chattian) - Early Miocene (Burdigalian) age. In this stratigraphic section, the Asmari Formation overlies the Pabdeh Formation and underlies the Gachsaran Formation. It consists of cream-colored limestone intercalated with marl. 182 thin sections were prepared and the benthic foraminifera distribution analyzed. Examination of large benthic foraminifera from the 228 m-thick Asmari Formation led to the identification of 3 biozones: the Lepidocyclina- Operculina- Ditrupa Assemblage Zone, Miogypsina-Elphidium sp. Assemblage Zone and the Borelis melocurdica- Meandropsina iranica Assemblage Zone. Manuscript profile
