The Andes range has many active volcanoes distributed in four volcanic zones separated by areas of inactivity. The Andean volcanism is a result of the [[subduction]] of the Nazca Plate and Antarctic Plate underneath the South American Plate. The belt is subdivided into four main volcanic zones that are separated from each other by volcanic gaps. The volcanoes of the belt are diverse in terms of activity style, products, and morphology.<ref>{{Cite journal |last1=González-Maurel |first1=Osvaldo |last2=le Roux |first2=Petrus |last3=Godoy |first3=Benigno |last4=Troll |first4=Valentin R. |last5=Deegan |first5=Frances M. |last6=Menzies |first6=Andrew |date=15 November 2019 |title=The great escape: Petrogenesis of low-silica volcanism of Pliocene to Quaternary age associated with the Altiplano-Puna Volcanic Complex of northern Chile (21°10′-22°50′S) |url=https://www.sciencedirect.com/science/article/pii/S0024493719303196 |journal=Lithos |language=en |volume=346–347 |pages=105162 |doi=10.1016/j.lithos.2019.105162 |bibcode=2019Litho.34605162G |s2cid=201291787 |issn=0024-4937}}</ref> Although some differences can be explained by which volcanic zone a volcano belongs to, there are significant differences inside volcanic zones and even between neighboring volcanoes. Despite being a typical location for [[calc-alkalic]] and subduction volcanism, the Andean Volcanic Belt has a large range of volcano-tectonic settings, such as rift systems, extensional zones, [[Transpression|transpressional faults]], subduction of [[mid-ocean ridge]]s, and [[seamount]] chains apart from a large range of crustal thicknesses and [[magma]] ascent paths, and different amount of crustal assimilations.
