Mineralogical ClassificationImproved data on kyzylkumite from its type-locality

▪ Reznitsky, L.Z., Suvorova, L.F., Ushchapovskaya, Z.F., Murashko, M.N., Barash, I.G. (2015): Improved data on kyzylkumite from its type-locality on the base of studied co-type material. [i]Zapiski RMO[/i], [b]144[/b](2), 61-70.
Abstract:
Investigation was focused upon the co-type of kyzylkumite from its type-locality — Koscheka deposit in Kyzylkum desert, where this mineral has been discovered. X-ray powder diffraction data and chemical composition of the co-type are analogous to kyzylkumite from the Southern Baikal region (Russia). Thus, structural data and crystal-chemical formula V2Ti4O10(OH)2 of the Baikalian analogue can be applied for kyzylkumite from the Kyzylkum desert also. Several new Ti-V-Fe phases, an iron hydroxide, unknown among mineral species, and two rare earth phosphates: churchite-(Y) and monazite-(Ce,Nd) have been found as intergrowths within kyzylkumite.
