This study highlights the tectono-metamorphic evolution of the lower crust in central Morocco from the Hercynian to the Quaternary from the study of granulitic xenoliths. After a first tectono-metamorphic event, the lower crust recorded heating associated with a moderate deformation preserved in sillimanite. Later, the lower crust interacted with basanite that brought the xenoliths up to the surface. This allows us to compare the evolution of the lower crust in the Rif and the Middle Atlas.
