Unnamed volcano

Central Andean Arc at 25.1°S

Tipo: Cono piroclastico
Altitudine: 4652 m
Ultima eruzione: Sconosciuto

This unnamed scoria cone near the Chile/Argentina border has produced lava flows to the east, visible in this July 2019 Planet Labs satellite image Monthly Mosaic (N is at the top; this image is approximately 8.5 km across). The visible flows have clear lobate or broader flow boundaries, levees, and pressure ridges, while other lavas have been buried by sand deposits. · Foto: Satellite image courtesy of Planet Labs Inc., 2019 (https://www.planet.com/).

Sintesi geologica

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.
