Cerro Chela

Chela is a volcano in Chile that was active between 3.75±0.5 and 4.11±0.25 million years ago. It is constructed on top of the 5.4±0.3 million years old rhyolitic Carcote ignimbrite. Its eruption products are mafic andesites. The volcano was degraded by glaciation but radial ridges and red-gray rocks as well as the uniform slopes indicate that it was a symmetric stratovolcano. The Pleistocene snow line was located at 4,800 metres (15,700 ft) altitude and moraines formed on the northern, western and southern flanks. Perhaps volcanically pre-formed cirques also developed. Cerro Chela is located south of Aucanquilcha, from which it is separated by the Portezuelo Puquíos. It forms a lineament with Cerro Carcote, Cerro Palpana, Miño Volcano and Volcan Las Cuevas that is oriented north-south.
