Biagioniite

biagioniite
(a) A loose aggregate of tabular crystals of bianchiniite, associated with ‘hyalophane’ and ‘chlorite’. Holotype material was sampled from this specimen. (b) Deeply altered earthy tabular crystals of bianchiniite associated with rhombohedral crystals of siderite and whitish microcrystalline fibrous aragonite. Both specimens from the Sant'Olga level, Monte Arsiccio mine, Stazzema, Apuan Alps, Tuscany, Italy (in a private collection).

Bicchulite, Gehlenite Locality: Fuka mine, Bitchu-cho (Bicchu-cho), Takahashi, Okayama Prefecture, Chugoku Region, Honshu Island, Japan (Locality at mindat.org) Size: 8.5 x 7.3 x 3.9 cm. Bicchulite is a very rare calcium silicate and this very rich and showy specimen is from the Type Locality - the Fuka Mine of Japan. Sharp, gray, rectangular crystals to 4 mm of bicchulite pseudomorphs after gehlenite crystals richly cover the quartz-rich matrix on this specimen. Gehlenite is also a very rare calcium silicate. The Fuka Mine recovered high grade calcite for the toothpaste industry and is noted for interesting high temperature boron species. Mineral

Billietite, Becquerelite Locality: Shinkolobwe Mine (Kasolo Mine), Shinkolobwe, Central area, Katanga Copper Crescent, Katanga (Shaba), Democratic Republic of Congo (Zaïre) (Locality at mindat.org) Size: 1.9 x 1.7 x 1.4 cm. Sharp, gemmy crystals of this extremely rare species, textbook in form, to just under 2mm poke out from protected pockets in this small matrix. The billietite are the orange crystals, easily seen and eye-visible. Becquerelite occurs on this piece as unusually gemmy, transparent yellow crystals underlying the Billietite. TYPE LOCALITY for both species. Mineral
