Condensed Griotte Facies and Cephalopod Accumulations in the Upper Devonian of the Eastern Anti-Atlas, Morocco

摘要: The Upper Devonian Griotte in the Tafilalt includes several types of thin variegated cephalopod limestones, ranging from a condensation facies to crinoidal limestones and nodular limestones. Excellent outcrops high fossil content facilitates reconstruction depositional history palaeogeography. Stratification patterns indicate that condensed were deposited shallow water, temporarily under turbulent conditions, while may have been formed slightly deeper neritic environment.
