Estructuración de los prismas litorales del Cabo de Gata: respuesta a los cambios climático-eustáticos holócenos

The internal structuration of the littoral wedge has been made by means of high resolution seismic stratigraphy analysis in front of Cabo de Cata sector (Almeria). Four seismic units have been described: Seismic Unit 7.- stratified with sigmoidal to parallel reflection configuration, related to coas...
