Lomas Blancas

Blancas, Lomas

Estratovolcán · Chile · 2268 m

The small light-brown area at the center of this NASA International Space Station image (with north to the bottom right) is Volcán Lomas Blancas. This small shield-like 2268-m-high stratovolcano of late-Pleistocene to Holocene age is located about 15 km SE of snow-capped Nevado de Longaví volcano (right-center). A 2.3-km-wide caldera, possibly formed by edifice collapse, can been seen opening to the SE. Pumice deposits probably originating from Nevado de Longaví blanket the volcano. The crescent-shaped lake at the upper left is Laguna del Dial.

Resumen geológico

Volcán Lomas Blancas is a small shield-like feature of late-Pleistocene to Holocene age (Moreno and Naranjo, 1991) located about 15 km SE of Nevado de Longaví. An open scarp to the SE side extends about 2.3 km from the summit. The central cone is basaltic. basaltic andesite aa lava flows extend 7 km from the scarp. Much of the volcano is covered by pumice deposits that probably originated from Nevado de Longaví.

Resumen de Wikipedia
