The Oligocene (Rupelian-Chattian) to Miocene (Aquitanian)-aged Asmari Formation is considered one of the most significant petroliferous reservoirs in the Middle East. The Oligocene-Miocene Asmari Formation represents diverse facies patterns in different parts of Zagros, so analysis of its facies in different provinces of the Zagros Basin is necessary. In this study, the sedimentary depositional sequences of Asmari Formation in the Firuzabad (south of Shiraz) and Bastak (west of Bandar-Abbas) sections in the Zagros Basin (Fras Platform) have been analyzed for distinguishing facies characteristics, interpreting the paleoenvironment and determining dominant depositional sequences. Based on field investigations and laboratory studies, 13 microfacies …

In this study, depositional environment and sequence stratigraphy of the Khoshyeilagh Formation has been investigated in three stratigraphic sections including Pelmis, Robat-e Qarehbil, and Kuhe Ozon in the northeast of Iran. The thickness of the Khoshyeilagh Formation in these sections are 182, 260, and 463 m, respectively. Based on the facies analysis of the Khoshyeilagh Formation, 3 clastic facies, 11 carbonate facies, and 1 hybrid facies were identified. The vertical and lateral changes of the Khoshyeilagh Formation show a shoreface marine depositional environment that begins with alluvial sediments and continues by marine sedimentation. According to these changes, a homoclinal ramp …
