Isotopic study of igneous and metamorphic rocks of Comallo-Paso Flores, Río Negro, Argentina

In the region that extends northwards from Comallo to Paso Flores in the Limay river (Fig.1), igneous and metamorphic rocks forming the Crystalline Basement of the area crop out. This basement outcrops discontinuously in the southwest of the North-Patagonian Massif and is referred to a Cushamen and...
