The tardi-Variscan structures in the Ibero-Moroccan domain show a brittle-ductile behaviour, overlapping the earlier main ductile stages, developed in the same orogenic process. The interaction between tectonic thickening, erosion and isostasy during the progressive colisional stages of the Variscan Wilson cycle was responsible by this rheological evolution. The tardi-Variscan deformation can not be understood ...
The Variscan belt is one of the major geological features of Morocco. Based on the paleogeography of the Paleozoic formations and related tectonometamorphic evolution, different domains have been proposed for this segment of the orogen. The Western High Atlas is one of such domains, which is usually considered as an external zone of the orogeny where most of its deformation is ascribed to a first and main Varis...
