oa Eustasy and Tectonic Controls on the Sedimentary Patterns in the Albian-Cenomanian Succession in the Lurestan (Zagros)

The Upper Albian-Turonian deposits in the Lurestan Area are attributed to the Sarvak Formation.Field observations and facies analysis indicate absence and presence of quartz grains and calciturbidites respectively which reflect the different tectonic regimes.Sudden establishment of Upper Cenomanian pyritic and glauconitic pelagic and hemipelagic facies containing packed ammonite even on the top of paleohighs, most propably suggest drowning of carbonate platform in the study area during late Cenomanian.
