Microfacies and depositional basin analysis of Cretaceous deposite at Korkouh area .

摘要

In order to microfacies studies of the Cretaceous deposits, a section called Korkouh was selected inKerman province in Central Iran area. The Korkouh is on the Bidou Formation with angularunconformity and underlain by paleogene conglomerates with an erosional surface. The studiedsection basically contains lime and dolomitic limestone with the thickness of 146 meters with newfossils such as foraminifera, bivalves and bryozoans. In general, foraminifera obtained fromKorkouh section indicate the existence of sediments in the age of Albian and Cenomanian. Basedon microfacies studies on the section three facies belts have been identified in Karkouh section thatinclude intertidal, lagoon and inner ramp. Studying of identified facies and comparing them with thepresent sedimentary environment showed that Korkouh outcrop facies have been deposited.
