Los Frailes ignimbrite plateau

Los Frailes is an ignimbrite plateau in Bolivia, between the city of Potosi and the Lake Poopo. It belongs to a group of ignimbrites that exist in the Central Andes and which includes the Altiplano–Puna volcanic complex. The plateau covers a surface of 7,500 square kilometres (2,900 sq mi)–8,500 square kilometres (3,300 sq mi) with about 2,000 cubic kilometres (480 cu mi) of ignimbrite.

The plateau features several putative vents, including Cerro Condor Nasa, Cerro Livicucho, Cerro Pascual Canaviri, Cerro Villacollo and Nuevo Mundo. The plateau was emplaced starting from 25 million years ago to the Holocene, when the Nuevo Mundo vent was active.
