Petrology of volcanic sequence in the Arroyo Ranquil Huao: Meseta de Somún Curá.. extra-andean patagonia
In the northern side of the extra andean Patagonia, in portions of Rio Negro and Chubut provinces, extensive basaltic lava flows plateaux type are exposed. On the southern side of the plateaux, in the Ranquil Huau stream valley, close to Telsen locality, a large succesion of volcanic and vocaniclast...
