Incapillo is one of at least six different ignimbrite or caldera volcanoes that are part of the Central Volcanic Zone, in Chile, Bolivia and Argentina. The Central Volcanic Zone is one of four different volcanic arcs in the Andes. About west of Incapillo lies the Maricunga Belt, where volcanism started 27mya and involved phases of ignimbritic and stratovolcanic activity, including Copiapo volcano, until activity ceased with the last eruption of Nevado de Jotabeche 6mya. South of Incapillo, the Pampean flat slab region is associated with tectonic deformation and lack of volcanic activity until Tupungato volcano farther south.
