Characteristics
Nevadaite is a pale-green to turquoise colored mineral belonging to the phosphate group. It exhibits a radial crystal habit consisting of prismatic crystals covering areas up to 2 cm. It has a pale-blue streak, a vitreous luster, and is not fluorescent. Nevadaite is in the orthorhombic crystal system and displays conchoidal fracture.{{Cite web|title = Nevadaite Mineral Data|url = http://webmineral.com/data/Nevadaite.shtml#.Vl-wN3arTIV|website = webmineral.com|access-date = 2015-12-03}}

Nevadaite was first discovered in the Gold Quarry mine near the town of Carlin, Eureka County, Nevada.{{Cite web|title = Nevadaite: Nevadaite mineral information and data.|url = http://www.mindat.org/min-25696.html|website = www.mindat.org|access-date = 2015-12-03}} The unique conditions and amounts of phosphate, vanadate, arsenate, and uranate in this area led to the formation of two new minerals; one being nevadaite and the other being goldquarryite. The Gold Quarry mine has been operated by The Newmont Mining Corporation since 1985 for the extraction of Carlin-type gold deposits.
Nevadaite was discovered in February 1992 by Martin C. Jensen and was approved by the International Mineralogical Association in 2002. It is also found in a copper mine in Kyrgyzstan.
