Structure of Morocco Margin at a far distance from the coast of d'El Jadida.
Julie Perrot
The continental-ocean transitions of the Moroccan margin are the focus of this study, specifically the mechanisms for crustal-thinning and the rupture. The goal of this study is to try to understand the pre-rift and the post-rift. To better understand the Moroccan margin this will be compared with the Nova Scotia margin.

The instruments used for this study are (OBS) and (OBH). They two methods give us the seismic reflection and the seismic refraction for the desired area. In addition to this, a seismometer will be used in the d'El Jadida coast.

Prior to thinning, the results show that the continental crust is 35 km thick and consists of 3 layers; after thinning, the crust is 8 km thick. Also, the superposition of the velocity model with the profile reflection yields a nice result that is likely a good coincidence. The observed and the computed gravity anomalies are very similar. The S1 magnetic anomaly is the beginning of the ocean. Comparing the Nova Scotia and the Moroccan margins show some differences and some similarities. The differences that appear are the serpentine mantle and that the Nova Scotia has longer transition areas. The two regions are similar in the following ways: same continental crust and the same stratigraphy. Also the results tell us that the evolution of the crustal thinning is anti-symmetric since the mantle is pushing up one of the sides.
