Abstract

The Upper Permian magmatism in the Cinco Villas Massif (Navarra, Western Pyrenees), is represented in two kinds ofcogenetic products: a) three reduced basins, with strongly altered basaltic sills and b) dolerite dykes, with two types (augite-rich and plagioclase rich), outcropping in Yanci-Aranaz area. The study of the chemical composition ofthe piroxenes indicates a sub-alkaline to alkaline affinity for thjs magmatism
