| Abstract | The lower Keuper of the central sector of Betic Cordillera shows a predominance of clays with variegated colours. They have intercalations of thin layers of sandstones (fine grain), gypsum and carbonates. Through sedimentological and stratigraphic analysis we can conclude that these materials are from a systems tract fluviocoastal further more it allows us to distinguish sorne different facies types which characterize the following subenvironments. They are set in a framework of mud flat, found on a vast tidal coastal lutitic plain. Terrigenous sediments (fine sands) from the mainland are deposited on the lutitic plain by ephemeral streams. In this coastal environment there are subenvironments of salt marsh, salt pans, sabkha, coastal lagoons, etc. The distribution in time and space of these facies was mainly controlled by the climate and the frequent incursions of the sea over the coastal plain, facilited by the flat geographical nature of coastline. |
