• Epidote - Wikipedia

    en.wikipedia.org/wiki/Epidote-(Sr) Epidote is an abundant rock-forming mineral, but one of secondary origin. It occurs in marble and schistose rocks of metamorphic origin. It is also a product of hydrothermal alteration of various minerals (feldspars, micas, pyroxenes, amphiboles, garnets, and others) composing igneous rocks.A rock composed of quartz and epidote is known as epidosite.Well-developed crystals are found at many ...

    geology.com/minerals/epidote.shtml Epidote in Rocks. Epidote is a rock-forming mineral.Many regionally metamorphosed rocks contain small amounts of epidote. Two rock types that contain significant amounts of epidote are epidosite and unakite.Locations where these rocks can be found are rare, but at those locations significant amounts of these rocks can be present.
