What is epidote rock?
What is epidote rock?
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.
How do you identify epidote?
Epidote usually ranges between yellowish green to pistachio green in color. Less often it is brownish green to black. In massive form it is usually translucent with a vitreous luster. Well-formed crystals from marble and pegmatite are often transparent.
Where is epidote found on Earth?
Epidote occurs in several different environments. It is found in hornfels and skarns in contact metamorphic rocks, and in metamorphosed limestone and in schists in regional metamorphic rock. It is also found in igneous rock in basalt and diabase, and is occasionally found in granite pegmatites.
Is epidote rare or common?
Facetable epidote is rare over 5 carat sizes.
What is epidote good for?
It is popular amongst crystal healers for its ability to clear congestion and energy blockages in the physical and subtle bodies. For this reason it is thought to be helpful dissipating tumors by releasing stagnant energies in the area. Epidote is thought to balance and stabilize the energy flow in the body.
What Colour is epidote?
yellowish green
Epidote has a characteristic yellowish green (sometimes weakly pleochroic) color. Extinction – Extinction is parallel in elongate grains (not in grains in other orientations).
Is epidote a tourmaline?
Epidote displays the distinctive features of being yellow-green in color, with a prismatic habit. However, the stone can still be mistaken for tourmaline. Upon closer inspection however, tourmaline lacks the cleavage that epidote has, and tourmaline has a hexagonal or triangular cross section which epidote does not.
Is olivine an epidote?
Epidote looks like green quartz, but is softer than quartz and does have a cleavage. Epidote can resemble olivine, however olivine is not found with quartz while epidote is often found with, and at times even embedded in, quartz.
Is epidote a quartz?
Epidote, a calcium aluminium iron sorosilcate mineral, occurs in nature as prismatic rod-like green crystals. When these grass-green crystals are present in colourless transparent quartz they form a complex and fascinating pattern, with fine specimans being highly prized by collectors.
