Resumo: | During the Toarcian, shelves undergo block-faulting with mechanisms of tilting. It results the break up of the Middle Atlas basin in subsident sectors separated by resistant ridges. This device is highlighted by strong variations of facies, more or less extended lacunar zones, reefs aligned on the ridges and of synsedimentary tectonics structures. Within the framework of mapping survey carried out in the south-west of Middle Atlas, a meticulous prospection of Bou Angar synclinal allowed the description of a new outcrop of Toarcian. This one offers good examples of extensional structures and bio-accumulations. These data, supplemented by other witnesses of the dynamic instability in the rest of the Middle Atlas, permit to propose a paleogeographic map of the Middle Atlas basin during the Toarcian. |

During the Toarcian, shelves undergo block-faulting with mechanisms of tilting. It results the break up of the Middle Atlas basin in subsident sectors separated by resistant ridges. This device is highlighted by strong variations of facies, more or less extended lacunar zones, reefs aligned on the ridges and of synsedimentary tectonics structures. Within the framework of mapping survey carried out in the south-west of Middle Atlas, a meticulous prospection of Bou Angar synclinal allowed the description of a new outcrop of Toarcian. This one offers good examples of extensional structures and bio-accumulations. These data, supplemented by other witnesses of the dynamic instability in the rest of the Middle Atlas, permit to propose a paleogeographic map of the Middle Atlas basin during the Toarcian. |
