Sequence stratigraphy of the Eocene-Miocene Mrayt Group, North-Western Rif (Morocco)

Résumé

Detailed sequence stratigraphy of the Eocene-Miocene Mrayt Group in North-Western Rif (Morocco), allow identifying the nature and the sources of the sediment supplies, the sedimentary facies and the depositional environments as well as the factors that controlled the sedimentation. This work made it also possible to identify 16 facies sequences that have never been described before. facies sequences, indicate that the sedimentation occurs under a complex hydrodynamics strongly influenced by river discharge, tidal currents and wave’s processes in an estuary, a tide dominated delta and waves and tide dominated nearshore. These depositional systems occur at the margin of the Maghrebian foredeep sedimentary basin under the interplay of climate, tectonic and eustacy.
