Kryzhanovskite
Kryzhanovskite is just a rare mineral that is phosphate is a part of the Phosphoferrite Group of minerals. Crystals are typically opaque to translucent, deep red-brown, dark blackish brown to light golden-brown, by having a vitreous to the lustre that is dull Moh’s hardness of 3.5 – 4. The formula of Kryzhanovskite is Mn2+Fe23+(PO4)2(OH)2 • (H2O) (Hydrated Manganese Iron Phosphate Hydroxide) and its molecular weight is 408.60gm.Kryzhanovskite was discovered at the Ak-Kezen’ pegmatite, Belogorskii Town, Kalba Range, Eastern Kazakhstan Province, Kazakhstan and named to honour Vladimir Il’ich Kryzhanovskii (1881–1947), Russian mineralogist, Curator regarding the A.E. Fersman Mineralogical Museum, Academy of Sciences, Moscow, Russia. The picture above programs a dark blackish brown gem that is faceted the east part of fast Creek, one km north of Lake Creek, Yukon Territory, Canada.
Kryzhanovskite circulation: from [the Ak-Kezen’ pegmatites,] near Belogorskii, Kalba Range, Kazakhstan. Abundant during the Clementine II pegmatite, Okatjimukuju farm, near Karibib, Namibia. Large crystals on the side that is east of Creek, one km north of Lake Creek, Yukon Territory, Canada. In the united states, in South Dakota, from the Bull Moose, Dan Patch, and Ferguson mines, near Keystone, and the Big Chief mine, one kilometer south of Glendale, Pennington County; through the Suggestion Top mine, 8.5 kilometer southwest of Custer, Custer County; in the Palermo #1 mine, near North Groton, Grafton County, New Hampshire. At Hagendorf, Bavaria, Germany. From the Bendada pegmatite, near Guarda, and into the Mangualde pegmatite, near Mesquitela, Portugal. From the Pinilla de Fermoselle pegmatite, Zamora, Spain.
