  1. References

{{coord missing|Argentina}}Cerro Beltran is an andesitic-dacitic volcano in the Andes. It erupted andesitic-dacitic lava flows between 14.1 and 7.7 mya. Based on geochemical considerations, the volcano formed from granite and plagioclase bearing, {{convert|33|-|40|km}} 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.
