Plio-Quaternary Volcanism in Northeastern Morocco: Petrography and Geochemistry of Outcrops with High Geothermal Potential

Cenozoic volcanic activity in Morocco started the Miocene and proceeded, after a short break, during Pliocene Quaternary. Calc-alkaline magmatic occurred first was accompanied by eruption of transitional lavas, followed Plio-Quaternary alkali basaltic activity, which emplaced within Neogene sedimentary basins Rif belt its foreland. From calc-alkaline to alkaline magmatism, passing through term, activities formed magnificent outcrops, very diversified their affinities, mineral compositions geochemistry. The petrographic study geochemistry Plio-quaternary rocks areas with high geothermal potential northeast show dominance Na-rich (basanites, basalts, tephrites trachy-andesites), trachy-andesites. Most samples exhibit an enrichment large-ion lithophile elements (LILEs) over high-field-strength (HFSEs). These results were used test global model Circum-Mediterranean Anorogenic Igneous Province (CiMACI) regional [1].
