BeschreibungThe 26 x 14 km composite late-Pleistocene Calabozos caldera produced major rhyodacitic-to-dacitic ashflow sheets of ~200-500 cu km magma each, collectively referred to as the Loma Seca Tuff, at 0.8, 0.3, and 0.15 million years ago. Eruptive activity has continued into the Holocene, forming the 20-25 cu km dacitic-to-andesitic Cerro del Medio complex at the southern end of the caldera and the four clustered vents of Descabezado Chico near the western caldera rim.
The late-Holocene 2.5 cu km Escorias dacitic lava flow from Descabezado Chico traveled >30 km to the south. Several hot-spring clusters are present along the margin of the central resurgent uplift within the caldera.
