Bornemanite

Saturday, February 19th, 2011

The chemical composition of mineral Bornemanite is indicated by the formula BaNa3{(Na,Ti)4[(Ti,Nb)2O2Si4O14](F,OH)2}•PO4. Bornemanite is usually found as late hydrothermal mineral. This mineral is most commonly found at its type of locality at Yubileinaya (Jubilee) alkalic pegmatite, Mt. Karnarsut, Lovozero massif, Kola Peninsula, Russia. Bornemanite was named for Irina Dimitrievna Borneman-Starynkevich (1890-), Russian mineralogist, Institute of […]

The chemical formula of mineral Boralsilite is indicated by Al16B6Si2O27. Boralsilite is most commonly found in a tourmaline – quartz intergrowth in granitic pegmatite cutting granulite-facies metapelitic rocks, and also known to be structurally related to sillimanite. Boralsilite is also commonly found at its type of locality at Stornes Peninsula, Larsemann Hills, Prydz Bay, East […]

Bonattite

Saturday, February 19th, 2011

The chemical formula of mineral Bonattite is indicated by CuSO4•3(H2O). Bonattite is a known to be a secondary mineral in a pyrite deposit. Bonattite is usually found at its type of locality at [Cantiere Macei,] Capo Calamita, Elba, Italy. This mineral was named for Stefano Bonatti (1902-1968), Italian petrologist, University of Pisa, Pisa, Italy. Mineral […]

Borocookeite

Saturday, February 19th, 2011

The chemical composition of mineral Borocookeite is indicated by the formula Li(1+3x)Al(4-x)(BSi3)O10(OH,F)8 [x = 0-0.33]. Borocookeite is usually found at a late stage pocket species in tourmaline-rich miarolitic pegmatites. This mineral is usually found at its type of locality at Malkhan gem tourmaline deposit, Central Transbaikalia, Russia. Mineral Borocookeite was named as the boron-rich analog […]

Borishanskiite

Saturday, February 19th, 2011

The chemical composition of mineral Borishanskiite is indicated by the formula Pd1+x(As,Pb)2, x = 0-0.2. Borishanskiite is also commonly found in massive and disseminated Cu-Ni sulfide ores. Borishanskiite is usually found at its type of locality at Oktyabr mine, Talnakh area, Noril’sk region, western, USSR. Borishanskiite was named for S.S. Borishanski, Soviet mineralogist. Borishanskiite is […]

Boothite

Saturday, February 19th, 2011

The chemical formula of mineral Boothite is indicated by CuSO4•7(H2O). Boothite is considered as a secondary mineral in sulfide ores. It is also known as an ephemeral mineral and virtually impossible to preserve in an artifcial environment. Boothite is commonly found at its type of locality at Alma pyrite mine, Leona Heights, Alameda Co. California. […]

Bonaccordite

Saturday, February 19th, 2011

The chemical formula of mineral Bonaccordite is indicated by Ni2Fe+++BO5. This mineral is most commonly found at small tabular body of nickeliferous serpentinite, probably a contact deposit, along the junction of quartzite and an ultramafic intrusive. This mineral can possibly be found in this environment because of a nickel-rich meteorite impact. Bonaccordite is most commonly […]

Bornhardtite

Saturday, February 19th, 2011

The chemical formula of mineral Bornhardtite is indicated by CoCo2Se3. Mineral Bornhardtite is usually known to be of hydrothermal origin. This mineral is most commonly found at its type of locality at the Trogtal quarry, near Lautenthal, and at Tilkerode, Harz, Germany. Bornhardtite was named after Dr. Wilhelm Bornhardt (1864-?), a German student of ore […]

Borcarite

Saturday, February 19th, 2011

The chemical formula of mineral Borcarite is indicated by Ca4MgB4O6(OH)6(CO3)2. Mineral Borcarite is usually found in kotoite marbles, near the contact with granodiorite. This mineral is commonly found at its type of locality at Snezhnoye boron deposit, Izvestkovyi stream, Tas-Khayakhtakh Range, Polar Ural Mountains, Russia. Borcarite was named for the BORate and CARbonate in the […]

Bonshtedtite

Saturday, February 19th, 2011

The chemical formula of mineral Bonshtedtite is indicated by Na3Fe++(PO4)(CO3). This mineral is most commonly found in veinlets associated with alkai-carbonate metasomatism of alkalic massifs. Bonshtedtite is usually found in drill core from the Vuonnemiok River Valley, and on Mts. Suoluaiv, Kukisvumchorr, Partomchorr, and Rest’yun, Khibiny massif, also in drill core from the Kovdor massif, […]
