'''Hydrothermal circulation''' in its most general sense is the circulation of hot water ([[Ancient Greek]] ὕδωρ, ''water'',<ref name="Liddell & Scott">Liddell, H.G. & Scott, R. (1940). ''A Greek-English Lexicon. revised and augmented throughout by Sir Henry Stuart Jones. with the assistance of. Roderick McKenzie.'' Oxford: Clarendon Press.</ref> and θέρμη, ''heat'' <ref name="Liddell & Scott"/>). Hydrothermal circulation occurs most often in the vicinity of sources of heat within the Earth's [[Crust (geology)|crust]]. In general, this occurs near [[volcanic]] activity,<ref>{{Cite journal|date=2008-10-15|title=Low-temperature hydrothermal alteration of intra-caldera tuffs, Miocene Tejeda caldera, Gran Canaria, Canary Islands|url=https://www.sciencedirect.com/science/article/abs/pii/S0377027308002163|journal=Journal of Volcanology and Geothermal Research|language=en|volume=176|issue=4|pages=551–564|doi=10.1016/j.jvolgeores.2008.05.002|issn=0377-0273|last1=Donoghue|first1=Eleanor|last2=Troll|first2=Valentin R.|last3=Harris|first3=Chris|last4=O'Halloran|first4=Aoife|last5=Walter|first5=Thomas R.|last6=Pérez Torrado|first6=Francisco J.|bibcode=2008JVGR..176..551D|url-access=subscription}}</ref> but can occur in the shallow to mid crust along deeply penetrating fault irregularities or in the deep crust related to the intrusion of [[granite]], or as the result of [[orogeny]] or [[metamorphism]].
