Geological summary
The Cerros de Guayaques group of N-S-trending rhyodacitic lava domes straddles the Chile-Bolivia border. The 10-km-long chain is located immediately E of the Purico pyroclastic shield. There is some evidence for Holocene activity, and the youngest domes appear to be N of the summit crater of the dome complex (de Silva and Francis, 1991). A well-defined summit crater was the source of the largest lava flows, which traveled 3 km to the SW. There are no records of historical activity.
