چکیده مقاله

In this study, sedimentary environment and depositional sequences were reconstructed based on distribution of microfacies in the sequence belong to the Qom Formation in the Kahak area. The formation was formed alternation of shale and limestone. The boundary between the Qom Formation and the volcanic rocks is unconformable. In addition, the Upper Red Formation in the Kahak area unconformably overlies the Qom Formation. In the study area, 6 microfacies, and 1 terrigenous facies (shale) for the Qom Formation were identified by study of these rock samples. The Qom Formation was deposited in an open-shelf carbonate platform in the study area. This platform can be divided into two environments that the environments consist of the inner shelf (restricted lagoon and semi-restricted lagoon) and middle shelf. Finally, two third-order sequences were identified based on distribution of microfacies in the Kahak area.
