Cerro Araral is an extinct volcano [3] located in the Andes on the border between Chile and Bolivia in the Potosí Department and in the Antofagasta Region. It has a height of 5647 metres, rising over a base of 3900 metres and covers an area of 109.4 square kilometres (42.2 sq mi). The edifice has a volume of 43.4 cubic kilometres (10.4 cu mi), down from 47.2 cubic kilometres (11.3 cu mi) due to erosion. Based on the erosion rate, the volcano is 1.9 [1]-2.75 and forms an alignment with Cerro Ascotan. Its formation may be linked to the Altiplano-Puna Magma Body, [4] which appear to have contributed to part of Araral's magmas. [3] The modern snowline on the mountain lies at more than 5,700 metres (18,700 ft) altitude. [5] There are archeological sites at its base and on its flanks. [6] The volcanism is at first andesitic and later becomes intermediary between andesite and basalt, [7] with olivine, plagioclase and pyroxene. [4]
