Summary:The Veiga granodiorite was intruded during the Upper Carboniferous into the core of the 'Ollo de Sapo' antiform, formed of Precambrian and Palaeozoic metasediments. Internal fabrics indicate that magma intrusion was contemporary with shortening. Measurement of feldspar orientations and anisotropy of magnetic susceptibility confirm this, and show that the cooling of the massif was coeval with an extensional motion of the Chandoiro fault.
