A mineral, commonly of a yellowish green (pistachio) color, occurring granular, massive, columnar, and in monoclinic crystals. It is a silicate of alumina, lime, and oxide of iron, or manganese.
A silicate of calcium, aluminum, and iron. Of yellowish-green color. The presence of epidote in rock indicates the advance of alteration.
Epidote - A pistachio-green mineral that forms as an alteration product of some feldspars.
a common metamorphic mineral, green in colour.
Ca(Al,Fe) Si 12(OH). A common metamorphic mineral formed at low temperatures and pressures, or a mineral formed by the hydrothermal alteration of plagioclase feldspar.
Family of silicate minerals containing mostly calcium, aluminum, iron and magnesium along with water. Epidote is apple green and generally forms very small, stubby, prismatic crystals. It often occurs in veins or as a green coating on fracture surfaces. Most common in metamorphic rocks, but occasionally forms in igneous pluton s that crystallize very deep in the crust.
A greenish-yellow mineral consisting of calcium, aluminum, iron and silica; it is common in metamorphic rocks, especially as a coating on joint surfaces.
A mineral which occurs in colors of green and brownish-green.
A silicate of alumina, lime, and oxide of iron, or manganese. It is commonly of a yellowish green (pistachio) color.
Epidote is a calcium aluminium iron sorosilicate mineral, Ca2(Al, Fe)3(SiO4)3(OH), crystallizing in the monoclinic system. Well-developed crystals are of frequent occurrence: they are commonly prismatic in habit, the direction of elongation being perpendicular to the single plane of symmetry. The faces are often deeply striated and crystals are often twinned.
