Jurbanite

Thursday, December 29th, 2011

The chemical formula of mineral Jurbanite is indicated by Al(SO4)(OH)•5(H2O). this mineral is usually found occurring at secondary crusts in humid tunnels in oxidized portions of sulfide deposits in aluminous rocks. This is apparently deposited directly from mine water at about 27 deg C and 100% humidity. Mineral Jurbanite is commonly found from its type […]

Juonniite

Thursday, December 29th, 2011

The chemical formula of mineral Juonniite is indicated by CaMgSc(PO4)2(OH)•4(H2O). This mineral is commonly found at metasomatically reworked calcite-phlogopite-clinohumite-magnetite ores in a calcite-dolomite carbonatitic stockwork zone. Juonniite is also considered as the scandium dominant analog of overite and segelerite. Juonniite is commonly found from its type of locality at Kovdor ultramafic alkaline complex, Yona or […]

Junoite

The chemical formula of mineral Junoite is indicated by Pb3Cu2Bi8(S,Se)16. Junoite is known to be of hydrothermal origin. This mineralis commonly found at its type of locality in the Juno mine, Tennant Creek, Northern Territory, Australia. Junoite was named for the Juno mine, Australia, in which it was first found. Junoite is known to crystallize […]

Junitoite

Thursday, December 29th, 2011

The chemical formula of mineral Junitoite is indicated by CaZn2Si2O7•(H2O). This mineral is commonly found occurring in a retrogressively altered tactite zone, and is closely related to the breakdown of sphalerite in the ores. Junitoite is commonly found from its type of locality at Christmas copper mine, Gila County, Arizona, USA. Mineral Junitoite was named […]

Jungite

Thursday, December 29th, 2011

The chemical composition of mineral Jungite is indicated by the formula Ca2Zn4Fe3+8(PO4)9(OH)9•16(H2O). Mineral Jungite is also commonly found from its type of locality at Hagendorf Sud pegmatite, Barvaria, Germany. Jungite was named for Gerhard Jung, German mineral collector who found the mineral. Jungite is known to crystallize in the orthorhombic system of crystal formation. In […]

Julienite

Thursday, December 29th, 2011

The chemical formula of mineral Julienite is indicated by Na2Co(SCN)4•8(H2O). Julienite is usually found occurring at Cobaltian wad in a white talc schist. This mineral is also most commonly found from its type of locality at Chamitumba, near Kambove, Shaba, Zaire. Julienite was named for Henri Julien (-1920), Belgian scientist. Julienite is also known to […]

Julgoldite-(Fe+++)

Thursday, December 29th, 2011

The chemical composition of mineral Julgoldite-(Fe+++) is indicated by the formula Ca8Fe3+2.7Al1.1Mg0.2Fe3+8Si12O42(OH)14. This mineral is usually found occurring at fracture filling in hematite-magnetite ore from the Amerika stope at Langban. Julgoldite-(Fe+++) commonly occurs at its type of locality at Langban, Varmland, Sweden. Julgoldite-(Fe+++) was named in 1971 by Moore for Julian Royce Goldsmith (1918-), American […]

Julgoldite-(Fe++)

Thursday, December 29th, 2011

The chemical composition of mineral Julgoldite-(Fe++) is inidicated by the formula Ca2Fe2+Fe3+1.5Al0.5(SiO4)(Si2O7)(OH)2·(H2O). Mineral Julgoldite-(Fe++) was named in 1971 by Moore for Julian Royce Goldsmith (1918-), American geochemist, University of Chicago. Julgoldite-(Fe++) is known to crystallize in the monoclinic system of crystal formation. In optical mineralogy, the monoclinic system of crystal formation comprises crystals having three […]

Juanite

Thursday, December 29th, 2011

The chemical formula of mineral Juanite is indicated by Ca10Mg4Al2Si11O39•4(H2O). Juanite is an alteration product of melilite. This mineral is most commonly found occurring from an Iron Hill, Powderhorn-Cebolla district, Gunnison County, Colorado. USA. Juanite was named for the San Juan Mountains, Colorado, USA. Juanite is known to crystallize in the orthorhombic system of crystal […]

Juanitaite

Thursday, December 29th, 2011

The chemical composition of mineral Juanitaite is indicated by the formula (Cu,Ca,Fe)10Bi(AsO4)4(OH)11•2(H2O). It is considered as a secondary mineral in copper arsenate and sulfate mineral assemblage from primary sulfide ores (tennantite, chalcopyrite, and pyrite). Juanitaite is known to be chemically related to mixite. Mineral Juanitaite is also most commonly found from its type of locality […]
