Las rocas graníticas del área de Estaca de Bares (provincias de La Coruña y Lugo).

Abstract

Two granitoids belonging to the two granitic series of the Spanish hercynian massif are studied. One type is the «Estaca de Bares» younger calcoalcaline granodiorite, and the other is the «El Barquero» alcaline granite. Both granitoids outcrop in the core of anticílnal structure which affect to «Ollo de Sapo» formation. Both kinds of rocks are compared and the possible origins of some aluminic minerals (cordierite, andalusite, sillimanite) in the moscovitie granite, are discussed.
