Central Andean Arc at 25.1°S
About Central Andean Arc at 25.1°S
An isolated basaltic andesite cinder cone was constructed on top of Miocene ignimbrites and lava flows between the Corrida de Cori range on the Chile/Argentina border and the Salar Río Grande in Argentina. Blocky lava flows from the cone descended in a broad lobe to the SE and in a narrow tongue to the E nearly to the Salar Río Grande. A second smaller vent lies about 800 m NW of the cinder cone. The relatively fluid lava flows display surficial breadcrust textures and were considered by Richards and Villeneuve (2002) to be very young, possibly of Holocene age.
