Estudio petrológico y geoquímico de las vulcanitas de los afloramientos de El Pimpollar, extremo nororiental de la Zona Surportuguesa

The Lower Unit of “El Pimpollar” volcanic outcrop (South-Portuguese Zone) is mainly composed of submarine dacites and andesites, with some subordinate basalts and trachyandesites. All these volcanic materials have intraplate affinities. The more basic rocks have alkaline character and show some diff...
