Short description: Volcano in the Andes
Cerro Beltrán is an andesitic-dacitic volcano in the Andes. It erupted andesitic-dacitic lava flows between 14.1 and 7.7 mya.[1] Based on geochemical considerations, the volcano formed from granite and plagioclase bearing, 33–40 kilometres (21–25 mi) thick crust.[2] Part of the volcano was later covered by ignimbrites coming from the Galán caldera eruption.[3]
The volcano is located next to the Salar de Antofalla.[2] It is one of the large long-lived volcanoes forming the Archibarca-Galan volcanic alignment, along with Tebenquicho, Galán and Antofalla.[1]
