Abstract

In the central High-Atlas, some ridges show outcrops of alkaline plutons. The petrographic facies in stratiform progressive succession range from troctolites to syenites, including gabbros and diorites. The geometric study of planar and linear fluidity indicate a dome shaped architecture and a diapiric emplacement, which was initiated under hot conditions and achieved under colder ones, as the host rock is free from any contact metamorphism. This emplacement is facilitated by a strike-slip system related to the opening of the central Atlantic ocean and the Tethys. There is an abridged English version. -English summary
