ABSTRACT: The Fahliyan Formation is a carbonate
sequence of Lower Cretaceous (Berriasian-Hauterivian) in age and was deposited
in the Zagros sedimentary basin. This formation is a part of Khami Group and is a reservoir rock in Zagros Basin. This formation was investigated by a detailed petrographic analysis
in order to clarify the depositional facies and sedimentary environment in the Kuh-e-Gadvan
in Fars Province. Petrographic studies led to the recognition of nine microfacies
that were deposited in four facies belts: tidal flat, lagoon, and barrier and
shallow open-marine. An absence of turbidite deposits, reefal facies, and
gradual facies changes indicate that the Fahliyan Formation was deposited on a
carbonate ramp.
