Permian volcanism of the Khenifra Massif (Central Morocco) Petrography and geochemical affinity

Abstract The Permian volcanic complex of Khenifra (Moroccan Central Hercynian Massif) manifests itself mainly by volcanic rocks of andesite, rhyolite, dacite, rhyodacite, ignimbrite and trachyte nature. These are rocks with a microlitic to porphyritic texture. They are formed by a primary paragenesi...

Summary:Abstract The Permian volcanic complex of Khenifra (Moroccan Central Hercynian Massif) manifests itself mainly by volcanic rocks of andesite, rhyolite, dacite, rhyodacite, ignimbrite and trachyte nature. These are rocks with a microlitic to porphyritic texture. They are formed by a primary paragenesis made of plagioclase, pyroxene, olivine, feldspar, biotite, amphibole and quartz and a secondary mineral association made of augite, calcite, chlorite and opaque. Intermediate and acidic rocks are widely represented in Khenifra basin. These facies are of calco-alkaline affinity.
