Geological Remarks

The hoggar is composed of NS horsts and grabens. Locally, Timgaouine horst, NS regional fault

Tectonic Setting

Precambrian formations : strongly metamorphic granito-gneissic Suggarian at the base passing to a quartzite-cipolin-amphibolite serie, then covered by the less metamorphic Pharusian series. Both series are cut or invaded by granitic complexes with various facies and crosscut by quartzofeldspathic veins
