AB The Lower Unit of “El Pimpollar” volcanic outcrop (South-Portuguese Zone) is mainly composed of submarinedacites and andesites, with some subordinate basalts and trachyandesites. All these volcanic materialshave intraplate affinities. The more basic rocks have alkaline character and show some differences with theequivalent vulcanites of the Iberian Pyrite Belt.The rhyolites of the Upper Unit are very rich in K and have geochemical characteristics intermediatebetween the silica rich igneous rocks related with volcanic arcs or collisional orogens. These rhyolitic rocksare different from other volcanic rocks with similar SiO2 content of the Iberian Pyrite Belt.The volcanic suite has a post-Middle-Visean age and its two units extruded in different tectono-sedimentaryenvironments
