Mise en évidence d’une phase tectonique au Santonien du versant Nord du Haut Atlas Occidental, Maroc
AbstractAt the level of the north hillside of the western High Atlas, only the training of limestones and dolomitic marls of Aït Abbes was recognized in Senonian. It is topped by the phosphated series. To highlight a tectonic action at the end of lower Santonian of Sidi Bou Othman's region and which is probably due to a halocinique phase, three cuts were been lifted on both sides of the Assif Aït Tabgaw. This tectonic phase appears by angular unconformity within the deposits of the training of Aït Abbes, microfaults, synsedimentary slidings, and monogenic breaches… It also structures the whole region at the high bottom or emergent low lands forming several small basins confined and supersaturated in brines. Then, following an important peneplanation, a platform of sebkha type is set up on the whole region. Some brief marine incursions reach the eastern basins.
