Abstract
The Bajocian-Bathonian red beds are affected by an extensive tectonic activity in the Atlantic passive margin of Morocco. Their sedimentatio n is controlled by NE-SW to NNE-SSW normal faults. In addition, the se quence formation is intruded by basaltic lavas and doleritic sills who se transitional affinity and within-plaque geodynamic setting are indi cated by petrographic and geochemical studies. We relate these tectoni c and magmatic activities to the initial stage of the oceanic accretio n in the Central Atlantic.
