About this map
Antofalla and other Andean volcanoes form because the Nazca Plate is subducting beneath the South American Plate. Antofalla volcano is located in a region with a "basins and ranges" topography, where during the Miocene ranges were uplifted and basins formed through tectonic movement. It sits on a basement formed by Eocene-Miocene sedimentary units over a much older crystalline basement.
