Structure sismique de la plate-forme Atlantique au large d'Agadir (Maroc sud-occidental)

Abstract

Offshore seismic reflection and well data have been used to establish the structural style of the offshore of Agadir and to extend the Atlas fabric into the deep-water domain. The obtained structural subsurface map exhibits a complex architecture resulting from the coexistence of normal, inverse, wrench faults and folds cored by Triassic salt. The seismic data indicate a structural style characterised by narrow, detached folding above Triassic salt layers. The strong similarities in the style of deformation between the Agadir offshore and the Cap-Tafelney fold belt, suggest that both of them form one continuous belt, which corresponds to the western termination of the Atlas alpine system.
