Raki, A.; Mridekh, A.; Manar, M.A.; Jemily, L., and Mhammdi, N., 0000. Dynamic model of Mio-plio-quaternary evolution of the Rharb continental shelf (NW Morocco).

The Northwest Atlantic margin of Morocco belongs to the huge Gulf of Cadiz complex situated within the boundary of the African and Eurasian tectonic plates. This provides an excellent geological context in which complex mechanisms occur, emphasizing the interconnectedness of geological processes across a larger scale. This study uses a coupled methodology of calibrated industrial seismic lines interpretation and boreholes data collected between the latitudes of Larache and Kenitra cities along the Moroccan Atlantic shelf. The main results show that Neogene structural evolution is dominated by Alpine compressive forces, as evidenced by reverse structures associated with the displacement of the PreRifane Nappe. These structures create space that leads to the development of the facing growth normal fault. Seismic stratigraphy analyses illuminate a Sebou paleo-valley succession, comprising 10 third-order Plio-Quaternary seismic sequences in response to glacio-eustatic cycles. These findings underscore the profound influence of regional and local tectonics intertwined with sea-level changes on the sedimentary history of the region.
