Epidote - Wikipedia
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, …

Epidote | Definition, Formula, Uses, & Facts | Britannica
epidote, any of a group of colourless to green or yellow-green silicate minerals with the general chemical formula A2B3 (SiO 4) (Si 2 O 7)O (OH), in which A is usually calcium (Ca), though manganese (Mn) or cerium (Ce) is sometimes substituted, and B is generally aluminum (Al), with the main substitution being ferric iron (Fe +3).

Epidote: Properties, Occurrence, Uses – Geology In
Epidote is a mineral belonging to the sorosilicate group, primarily composed of calcium, aluminum, iron, and silica. It typically occurs in metamorphic rocks, where it forms as a result of the alteration of primary minerals under high-pressure and temperature conditions.
Epidote - Geology is the Way
Epidote is a calcium aluminium sorosilicate and the main member of the homonymous Epidote group, which comprises other rock-forming and accessory minerals like clinozoisite, zoisite, piemontite, and allanite.
Epidote: The mineral epidote information and pictures
Epidote is one of the most outstanding display minerals. The finest and most desirable form of this mineral is in delicate elongated crystals that are extremely lustrous and often interconnected. This form is highly treasured by collectors and creates one of the finest mineral showpieces.
Epidote-Clinozoisite - University of North Dakota
Epidote has general formula Ca 2 (Al,Fe 3+) 3 Si 3 O 12 (OH). The most Fe-rich epidotes have about 35% of the Al replaced by Fe 3+. These minerals may be hard to identify if present as small accessory grains. When larger, identification is simpler.
