'''Epidosite''' ({{IPAc-en|ᵻ|ˈ|p|ɪ|d|ə|s|aɪ|t}}) is a highly altered [[epidote]] and [[quartz]] bearing rock.<ref>{{cite journal |author=Peter T Flawn |journal=American Journal of Science |doi=10.2475/ajs.249.10.769 |title=Nomenclature of epidote rocks |year=1951 |volume=249 |issue=10 |pages=769–777|bibcode=1951AmJS..249..769F |doi-access=free }}</ref>  It is the result of slow [[hydrothermal alteration]] or [[metasomatism]] of the [[basalt]]ic [[sheeted dike complex]] and associated [[plagiogranites]] that occurs below the massive sulfide ore deposits which occur in [[ophiolite]]s.<ref name=Banerjee>{{Cite web |url=http://web.uvic.ca/~kgillis/banerjee%20et%20al.pdf |title=Banerjee, Neil R., et. al., ''Discovery of epidosites in a modern oceanic setting, the Tonga forearc,'' Geology, February, 2000 v. 28, no. 2, p. 151-154 |access-date=2011-12-22 |archive-date=2016-03-04 |archive-url=https://web.archive.org/web/20160304090901/http://web.uvic.ca/~kgillis/banerjee%20et%20al.pdf |url-status=dead }}</ref><ref name=Varga>[[Lori Bettison-Varga]], Robert J.
