Caracterización geológica de los afloramientos de El Pimpollar, extremo nororiental de la Zona Surportuguesa
(2006)Two volcanic units can be distinguished in the “El Pimpollar” outcrop (eastern South-Portuguese Zone). The Lower Unit is composed mainly of submarine dacites and andesites, with some subordinated basalts and trachyandesites. ... -
Datación palinoestratigráfica del volcanismo en la sección de la Ribera del jarama (Faja Pirítica Ibérica, Zona Surportuguesa)
(Sociedad Geológica de España, 2002)The levels of black slates that appear through the whole series of volcanic materials, have been revealed as a high-priority objective when carrying out studies detailed in the IPB, since they are constituted as a good ... -
El Macizo de Pradorramisquedo: petrografía, geoquímica y aplicaciones industriales
(Sociedad Geológica de España, 2002)The Pradorramisquedo massif (NW Iberian Variscan Belt) is a granitic pluton emplaced into migmatized augen gneisses and banded gneisses that of"Olio de Sapo Croup". Its intrusion is subsequent to the two main deformative ... -

(2006)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 ... -
Geocronología U/Pb del volcanismo ácido y granitoides de la Faja Pirítica Ibérica (Zona Surportuguesa)
(Sociedad Geológica de España, 2002)Three samples have been analyzed, two of them belong to the volcanic ones from the IPB and a third to the rocks plutonics of the BSN. The age belonging to the granitoid of Campofrio is of 354,4 +5/-4 m.y. The ages obtained ... -
Petrología del macizo granítico de Manzalvos-Castromil (NO de la Zona Centro-Ibérica)
(Sociedad Geológica de España, 2002)The Manzalvos-Castromil massif (NW Iberian Hercynian Belt) is mainly composed of granitoids that define an alumino-potassic association. Magmatic microgranular enclaves and scattered amphibole-biotite intermediate rocks ... -
Propuesta de estructura geológica para el depósito gigante de sulfuros masivos volcanogénicos de Río Tinto, Faja Pirítica Ibérica
(2010)New field reconnaissance around the Río Tinto Mine led to a better structural knowledge on the area. The improved map support a different geological evolution on this sector determined by an earlier extensional event, ...
