The chemical composition (whole rock) of Upper Permian basaltic sills and dolerite dykes outcropping in the Cinco Villas Massif (Western Pyrenees) allow to recognize: a) their basic, unevolved composition, b) their cogenetism, and c) their subalkaline to alkaline geochemical affinity. These features are similar to those of the Anayet-Ossau basaltic rocks, and suggest their relationship with a common basaltic event, related to post-orogenic extensional tectonics
