The Jurassic and Lower Cretaceous carbonate platform of the Mazagan submarine plateau is composed of 3 main facies units: Facies A comprises neritic shallow marine lithologies of the Oxfordian to Kimmeridgian carbonate ramp and the beginning of the Tithonian carbonate platform. Facies B contains hemipelagic sediments which are the result of platform defacing processes mixed with pelagic influx. Facies C is composed of intertidal to shallow subtidal sediments, deposited on the top of the platform. The depositional history of the carbonate platform is strongly influenced by blockfaulting and sea level changes. During the formation of the Mazagan Escarpment subsiding marginal blocks developed a steep slope composed of numerous steps of different vertical and horizontal extension.
