Quimsachata-Oroscocha

Domo de lava · Peru · 3848 m

A lava flow at Quimsachata scoria cone is visible in this October 2020 Planet Labs satellite image monthly mosaic (N is at the top). The flow erupted about 11,500 years ago and is approximately 4.7 km in the NW-SE direction. The smaller lava flow directly to the north was erupted from the Oroscocha lava dome about 6,400 years ago. These are the northernmost young volcanic centers in Perú.

Resumen geológico

The Quimsachata-Oroscocha group consists of two late Pleistocene and Holocene monogenetic volcanoes at the foot of the Cordillera Oriental, far east of the main volcanic front. Quimsachata is a high-potassium andesitic scoria cone surrounded by a lava shield that was erupted in flat terrain along the Vilcanota River about 11,500 years ago. Oroscocha is a rhyolitic lava dome with a short, thick lava flow erupted from a N-S-trending fissure about 6,400 years ago.
