After numerous lithologic and paleontologic investigations, a precise biostratigraphic scale was built, especially by foraminifers for Morocco to date limestones in platform, but also turbidites because carbonate and detrital sediments are mixed in platform and basin. Four marine basins more or less connected together, existed in this period: Sidi Bettach near Rabat, Central Morocco between Oulmes, Azrou and Khenifra, Jebilet and High-Atlas near Marrakech, and Eastern Meseta basins between Fes and Oujda. On mixed carbonate and detrital platforms surrounding the basins or on horsts within the basins, the eustacy prevails upon the tectonics, and consequently sequences are more similar to the Vail’s type. Comparisons between Moroccan sequences of platforms and basins, and sequences of platforms in Belgium and Great Britain show that s...

The series, essentially constituted by shales and limestones, are interrupted by two volcanic events, respectively in V3b,-Early V3c and in Ser- pukhovian El. The latter are coeval with two major tectonic phases, first in V3b, with horst and graben structuration, created by important faults N70, and opening of the Beni-Snassene, Jerada and Mekam basins. A second major, phase at the V3c-Serpukhovian boundary, permits the opening of the Debdou-Tazekka basin with faults N30. (0 Academic des sciences / Elsevier, Paris.)
