Cerro Guayaques

Guayaques

Domo de lava · Chile-Bolivia · 5598 m

The irregular 10-km-long N-S-trending chain just left of the center of this Landsat image is Cerros de Guayaques. These rhyodacitic lava domes straddle the Chile-Bolivia border. The 10-km-long chain is located immediately east of the Purico pyroclastic shield, part of which is visible on the left side of the image. A well-defined summit crater was the source of the largest lava flows, which form the lobate flows that extend 3 km to the SW. There are no records of historical activity from Guayaques volcano.

Resumen geológico

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.

El cerro Guayaques es una montaña fronteriza entre Bolivia y Chile, ubicada en el Altiplano andino. Su cima llega a una altitud de 5.626 metros sobre el nivel del mar. Forma parte de la cadena Guayaques de 10 km de largo de domos de lava riodacítica de tendencia NS que atraviesa la frontera entre Chile y Bolivia unos 10 kilómetros al este del complejo Cerro Toco - Puricó. El cerro Guayaques se constituye en el punto más austral de Bolivia, ubicado administrativamente en el municipio de San Pablo de Lípez de la provincia de Sud Lípez en el lado boliviano.
