La sección Messiniense - Plioceno de Crevillente (Cordillera Bética oriental): expresión de la crisis de salinidad del Mediterráneo

Abstract

A composite stratigraphic section in Crevillente (eastern Betic Cordillera) is studied. It represent complete stratigraphical and paleontological record of the Messinian and Lower Pliocene. Two discontinuity surfaces related to the Mediterranean salinity crisis are analysed: a intra-messinian surface which coincides with a sea-level fall leading to the emergence of this area far from marine influences; and an uppermost Messinian unconformity, with strong erosional character, overlied by marine Lower Pliocene transgressive deposits.
