Fábrica magnética del plutón de Marimanha (Pirineo central)

The structural and magnetic fabric study of the Marimanha granite (Axial zone of the Pyrenees, Catalonia), provides new data to characterize the zonation and the internal structure of the pluton. The Marimanha granite intrudes Cambro-Devonian metasediments of the Axial zone of the Pyrenees. The zona...
