چکیده

The Fahliyan Formation (Volgian - Neocomian) (Early Cretaceous) is a part of the Khami Group. This formation has been studied in two sections in the center of Fars (southwest of Arsenjan city and west of Sivand city) to determine its facies, sedimentary environments and sequence stratigraphy. The deposits of the Fahlyian Formation consist of carbonate facies which are deposited in a Carbonate Rimmed Shelf. Two sequences with both type 1 and type 2 sequence boundaries are recognized within these deposits which are in accordance with a part of Zuni mega sequence (Lower Zuni III). The age of this formation is referred to the Tithonian- Vallanginian (Early Cretaceous).
