Facies, Sedimentary Environment and Sequence Stratigraphy Study of Jahrum and Asmari Formations in Kaftarak Section, Southeast of Shiraz (Fars Province)

In this research, a stratigraphic section called Kaftarak Section related to Jahrum and Asmari Formations was selected. The sediments in this section are 286 m thick. Generally, index mirofacies of the studied thin section in Jahrum Formation includes wackestone, packestone, Grain stone, Dolomite microfacies and Dolomite Limestone, which lie in environmental groups of Intertidal(A), lagoon(B) and shoal(C). Index mirofacies of the studied thin section in Asmari Formation include Mud stone, wackestone, packestone and grainstone, that lie in environmental groups of Intertidal(A), lagoon(B), shoal(C) and open marine(D). Allochem and clastic elements of the mentioned microfacies could be Intraclast, Bioclast, Extraclast and ploide. Based on the Sequence Stratigraphic studies, Jahrum Formation sediments include a 3rd order sediment sequence and Asmari Formatin sediments include two 3rd-order sediments sequence.
