Background:

Cerros de Tocorpuri (or Volcán Tocorpuri) is a stratovolcano complex on the Chile-Bolivia border with a youthful-looking rhyolitic lava dome, Cerro la Torta, at its western foot. The international border swings around the eastern rim of a 1.4-km-wide crater that truncates the summit; the crater lies wholly within Chile. It was considered by González-Ferrán (1995) to be of Pleistocene-Holocene age. Cerro la Torta has been considered to be of Holocene age due to its youthful morphology, but its age is not known precisely and Potassium-Argon dating indicates only that it is less than a million years old. Comparison with similar dated domes nearby suggests it is of Pleistocene age (de Silva, 2007 pers. comm.). The circular, roughly 5 km3 Cerro la Torta was erupted from a central vent and is surrounded by a flat-topped surface with wrinkled flow ridges. The flow terminates in steep, talus-covered margins about 150 m high. Lava extrusion was preceded by minor silicic explosive eruptions.
