Sedimentary, tectonic and magmatic markers of the Phanerozoic rifting on the northern side of the High-Atlas of Marrakech, Morocco.

This field trip is presenting the sedimentary, tectonic and magmatic markers of the Phanerozoic rifting. In addition, the reservoir rocks on the northern side of the High-Atlas of Marrakech, Morocco.

The High-Atlas Mountains integral part of the Atlaso-mesetien domain, and is an intracontinental orogeny formed during the (Meso-Cenozoic) convergence phase of the Africa/Europe plates (lithospheric reduction) and to thermal processes (such as the warm of the mantle anomaly). This excursion aims to show sedimentary, tectonic and magmatic aspects associated with the rifting of the Atlas during the Triassic-Jurassic period. The High-Atlas of Marrakech is one of the most representative regions of the magmatism studies during the Precambrian III, carboniferous basins (turbidities), Triassic (alluvial plain, diapir,…) periods in the cartographic, tecono-sedimentary, petroleum angle (reservoir, seal,...), mining point of view.
