Cochiquito Volcanic Group, Volcanic group in Mendoza Province, Argentina

The Cochiquito Volcanic Group is a small volcanic field north of Buta Ranquil, in Mendoza Province, Argentina, at the confluence of the Rio Grande and Rio Barrancas. It consists of the central Cochiquito stratovolcano, estimated to be of Pleistocene–Holocene age, surrounded by eight satellite cones, among them the Sillanegra pyroclastic cone complex and the small Ranquil del Sur stratovolcano. Its rocks are mainly basalts with lesser andesites.

The Cochiquito Volcanic Group lies north of Buta Ranquil, at the confluence of the Río Grande and Río Barrancas in Mendoza Province. Its main peak, Volcán Cochiquito, is a stratovolcano built mainly of basalts with lesser andesites, estimated to date from the late Pleistocene to the Holocene. Eight satellite cones surround it, among them the pyroclastic cone complex Volcán Sillanegra and the small stratovolcano Volcán Ranquil del Sur.

The name Cochiquito is a diminutive, and the group lies just north of Buta Ranquil, the nearest settlement and usual access point. The field sits at the confluence of the Río Grande and Río Barrancas, a junction that also marks the provincial boundary between Mendoza and Neuquén.

The group lies north of Buta Ranquil, in Neuquén Province, near the confluence of the Río Grande and Río Barrancas; the main peak is Volcán Cochiquito, with Volcán Sillanegra and Volcán Ranquil del Sur among eight satellite cones. Approach from Buta Ranquil, and plan for the exposed, changeable weather of the northern Patagonian Andes.

The group's eight satellite cones include Volcán Sillanegra, described in sources as a pyroclastic cone complex, and Volcán Ranquil del Sur, a small stratovolcano. The field lies north of Buta Ranquil, near the confluence of the Rio Grande and Rio Barrancas.
