Evolución sedimentaria de un nuevo sistema turbidftico en el Atlántico sur: el sistema turbidftico de Agadir

Abstract

The Agadir turbidite system is located on the Morocco continental margin and the Agadir Basin (South Atlantic), and extends from 200 m to 4300 m water depth. Its establishement seems to have occured during the Oligocene, when the Agadir Canyon was formed. This canyon represents the main valley that feeds the turbidite system. The sediments transported through the Agadir Canyon deposited on the Agadir Basin, developing canyon, channel, overbank and depositional lobe deposits. From the Oligocene to present, this turbidite system has migrated laterally being controlled by the (paleo)topography and the local tectonics. Its vertical sedimentary succession is clearly retrogradational. This retrogration is interpreted as the result of the interplay between tectonics and climate
