        Abstract In this study two stratigraphic sections named Tang-e Ab as type section and Tang-e Nimbashi analyzed in order to study lithostratigraphy and microfacies of Jahrum Formation in Fars province. Both sections, Tang-e Ab in northern flank of Jahrum Anticline (East of Jahrom) and Tang-e Nimbashi in northern flank of Tudej Anticline (West of Estahban) located in Interior Fars Sub-Zone at Zagros folded belt. Tang-e Ab section included 450 meters of conglomerate, limestone, nodular marly limestone, dolomitic limestone and dolostone with thin, medium, thick and very thick bedding and Tang-e Nimbashi section included 562 meters of limestone, marly Limestone, nodular marly limestone, dolomitic limestone and dolostone with very thin, thin, medium, thick and very thick bedding. The result of field and laboratory observations is determination of 10 lithostratigraphic unit and 10 microfacies class in Tang-e Ab and 7 lithostratigraphic unit and 11 microfacies class in Tang-e Nimbashi, in both Sections 3 sub-environments included: open marine, lagoon and peritidal and sedimentary settings corresponded on a carbonate platform of homoclinal ramp.

        Zagros Sedimentary basin is located in the south and southwest of Iran and Pabdeh Formation is one of the most important Cenozoic units of Zagros Sedimentary basin. In addition, Pabdeh Formation is of special importance as one of the source rocks of Zagros Sedimentary basin. In order to study the Lithostratigraphic and Biostratigraphic rocks of Pabdeh Formation, the section of Ilam dam in the northwest of Zagros sedimentary basin has been selected and sampled. 360 samples were taken, of which 260 washing samples and 100 thin section samples were prepared. Based on the studies performed on these samples, 25 genera and 105 species have been identified in the Ilam dam section. 26 biozones and 2 sub-biozones have been identified based on the biological zoning of Wade et al., 2011 in the Tethys area. Based on the identified biozones, the age of Pabdeh Formation in the Ilam dam section, Middle Danian-Early Aquitanian has been obtained. The deposits of Pabdeh Formation in the section of Ilam dam have a thickness of 764 m (beginning of Pabdeh to the beginning of Kalhor anhydrite) which includes purple shale units (2 Units), marl limestone with lower limestone, cherti limestone, marl limestone with upper limestone. The lower boundary of Pabdeh Formation in this section is conform and continuous with shales and marls of Gurpi Formation but its upper boundary with the gypsums of the Asmari formation is most likely accompanied by a disconform.
