Quimsachata-Oroscocha

Kubah 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.

Ringkasan geologi

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.

Ringkasan Wikipedia

Quimsachata(kemungkinan dari Aymara dan Quechua kimsa tiga,[3] Gunung Pukina chata[4]) adalah gunung berapi yang sudah punah di Andes, Peru. Gunung ini terletak di Wilayah Cusco, Provinsi Canchis, sekitar 24 kilometer barat laut dari kota Sicuani.[5] Gunung ini terbentuk dari dua pusat yang terpisah, satu aktif 11.500 tahun yang lalu yang membentuk kerucut scoria dan ladang lava, serta satu lagi yang aktif pada tahun 4450 Sebelum Masehi yang membentuk dua aliran lava dan kubah lava.
