Facies Analysis and Depositional Environment of the Sarvak Formation (Cenomanian) in the Zagros Basin (SW of Iran)

May 1, 2021 Environment and Earth Science 0

Two stratigraphic sections of the Sarvak Formation were chosen for this analysis, the Bavan and Kherameh sections. The Sarvak Formation has been studied over 379.5 metres and 260 thin parts. Foraminifers and index microfacies have been discovered. Boundstone, Wackestone, and Packstone are index microfacies. Bioclasts have been found to have a higher frequency than the other microfacies elements. 14 sublithofacies have been identified in three depositional environments based on the type and abundance of skeletal and nonskeletal grains, as well as the type of matrix. 3) The sea is open. The determined microfacies were deposited in a Homoclinal Ramp Carbonate Platform. The Sarvak Formation is Cenomanian in age, according to micropalentological evidence.
