Abstract:
Continuous subbottom profiling on the northwestern African continental terrace indicates that depositional, erosional, and deformational processes have been active since Cenozoic time. The more complex structural features (folds and faults) are related to the Alpine tectonics of extreme northwest Africa. Less complicated structures occur toward the south. Following widespread Pleistocene erosion, strata reached thicknesses of 35 m. The 150-m depth of the Moroccan shelf break probably is related to downbending associated with the last phases of the Alpine orogeny.
In this region crustal movements have had a strong effect on the framework and attitude of the shelf. Differential erosion of the deformed and warped beds has produced a rough shelf surface.
