Location: Prehnite and Epidote are found in numerous locations around the world. Locations where these rocks can be found are rare, but at those locations significant amounts of these rocks can be present. Epidote is an aluminum-iron mineral that can be found in either crystal or stone form. A variety of epidote from the Arendal iron mines in Norway, which occurs in well-developed green crystals. Good to splendid crystals are found in Untersulzbachtal (Austria), "arendalite" from Arendal (Norway), (Isere) France, the Naziamsky mountains (Urals, Soviet Republics). Perfect for healers and spiritual seekers. In that series, the iron of epidote is gradually replaced by aluminum to the end member clinozoisite composition of Ca2Al3(SiO4)(Si2O7)O(OH). It is also found in igneous rock and occasionally forms in granite pegmatites. Well-formed crystals from marble and pegmatite are often transparent. Olivine - (Fe,Mg) 2 SiO 4 Olivines are an important rock-forming mineral group. Allanite is more commonly found in igneous rocks such as pegmatites. Epidote is often found in very fine crystals, making it desirable for mineral collectors. Unakite is popular as a tumbled stone. Less often it is brownish green to black. 2 T.47N. Epidote or clinozoisite occurs in abundance and carries much of the calcium of the basaltic precursor rock. It can also be found in schists and marbles. Two rock types that contain significant amounts of epidote are epidosite and unakite. The color of Epidote is almost invariably green, in all different shades and tones, with a pistachio color habit being very typical. It is formed frequently also during the metamorphism of an impure limestone. This form is highly treasured by collectors and creates one of the finest mineral showpieces. The minerals of the epidote group form at low temperatures in low to medium-grade metamorphic rocks. In addition, it is frequently found as vug or vein fillings in these rocks. Large deposits of Epidote have been found in the USA, Mexico, Russia, France, Austria, Norway, Bulgaria, South Africa, Mozambique, and Pakistan. Perhaps the world's most classic Epidote locality is in the Austrian Alps, in Knappenwand in the Untersulzbach Valley, where large sharp and lustrous crystals are very highly regarded. It is considered to be a semiprecious stone. It is particular common in metamorphosed basalts and gabbros where it replaces plagioclase, pyroxene and olivine. Those of metamorphic origin is a mineral found in basic rocks that contain a lot of calcium and aluminum. It takes place as monoclinic crystals in pegmatites. Epidote can be found in Austria, Italy, Mexico and the USA. "A" is a pairing of calcium, manganese, strontium, lead, or sometimes a rare earth element. gem and mineral collectors.
