The mineral occurs as irregular grains up to 4 mm in size and as aggregates up to 6 mm in drill cores from the western and northwestern slopes of the Lovozero Massif, Kola Peninsula (Tavaiok and Angoundasiok Rivers, Alluaiv Mt.). rt occurs in foyaites consist- ing of microcline (partly albitized), nepheline, sodalite, aegirine, alkali amphibole, and accessory eudialyte and ramsayite. rt is a primary mineral, formed late in the sequence, and is closely associated with ramsayite. The mean of three partial analyses by L. P. Voronina, M. E. Kazakova, and G. V. Kalenchuk and R. L. Timofeeva, is SiO:39.39, 2rO240.35, TiOr 0.60, FeeOa+FeO 0.31, NazO 16.03, KrO 0.94, HzO- 0.35, HuO+ 0.95, corresponding to (Na, H)zZrSizOz, with Na:H:5:1. The ratios Zr/Hf, determined by I. D. Shevalevskii is 47-51. The mineral is decomposed by HCl, HNO3 and HzSOr. Keldyshite is white, luster vitreous to greasy, hardness I57-231 kg/sq. mm, correspond- ing to 3.8-4.3 Mohs, G about 3.30. Very brittle, fracture irregular. Optically biaxial, (-), a 1.67O,y 1.710. Strong dispersion of optic axes: 2V 60" for red, 78' for yellow, lI2" for blue, i.e. the mineral is (*) in blue light. Two poor cleavages were found under the micro- scope which intersect at about 90'. The better cleavage gave: P (pole of cleavage) to "r 75" , to B 57", to a 35'.

The mineral occurs in the oxidized zone oI the Osarizawa copper mine, Akita Prefecture, Japan, as a powdery crust on anglesite and limonite. Other minerals present in the oxidized zone are linarite, azurite, brochantite, malachite, and kaolinite. The name is for the mine. See also pp. 1079-1093, this number of this journal.
Mourite B. V. KopcnnrovA, K. V. Srvonrsovl, N. I. Srr.aNrrEvA, G. A. SroonnNro AND L. V. Mrruerr,ova. Mourite, a new supergene uranium-molybdenum mineral. Zapiski, Vses. Miner aJ. Obshch.,9l (l), 67-7 1 (1962) (in Russian).
The mineral occurs as violet nodules, crusts, and plates in the supergene zone of a de- posit, the hypogene ore of which contains pitchblende, molybdenite, jordisite, pyrite and other sulfides. Umohoite occurs directly below the supergene zonel the latter contains "U-Mo blacks," iriginite, U-containing powellite, sodium uranospinite, uranophane and tyuyamunite, as well as goethite, jarosite and kaolinite; the mine waters are acid sulfate waters. In places, mourite is forming on corroded umohoite. In the mine workings, mourite decomposes to ilsemannite. The locality is not given, as usual. Microchemical analysis by N. N. Kuznetsova gave MoOs 63.67,UO, 19.38, UOB 2.40, SiO2 1.72, AlrOa 1.36, Fe2O30.57, MgO 0.49, CaO 2.09, KsO 0.58, NarO 0.54, HzO- 1.67, HrO+ 6.07, sum 100.54le (given as 100.527d .In addition, small amounts oI Mn, Cu, Pb, Tl, Sb, Ti and Ag were found spectroscopically. It is assumed that the minor components are due to admixtures (this is especially doubtful for CaO), the ratios are (UOzfUOa) :MoOr:HzO:1:5.5:5.3. However, the oxidation states could not be determined; the violet color of the mineral and the incompatibility of U6+ with Moa+ in acid solution makes it probable that Mo is present as Mo6+ or Moa+, or both. Mourite dissolves with difficulty in conc. HCI on prolonged heating, dissolves in conc. IINOa with separation of molybdic acid, is insoluble in HzSOr or l1Vo KOH, dissolves in 2O/6 NazCOt solution on heating. A dehydration curve shows gradual loss of 3.5/a HzO up to 200", and 4Vo HzO from 200-250".

When heated at 750o, most of the mineral volatilized leaving a small yellow residue giving the *-ray pattern of UrOs. The mineral occurs in fan-shaped, radiating-fibrous, or vermiform aggregates of plates with rectangular outlines of a few microns size. Streak violet-blue. G greater than 4.2. Hardness 75 kg/sq. mm, corresponding to about 3 on the Mohs scale. Indices of refraction could not be measured because of the small size and deep color; they exceed 1.780. Elonga- tion positive. Extinction inclined to cleavage about 10o. Pleochroism distinct, dark blue- violet on Z, pale violet-blue with greenish tint on X and Y.

The mineral was found in rock salt with boracite, kaliborite, pinnoite and anhydrite at a depth of about 400 m in the Kungur saline rocks (Inder basin? M.F.), as fine-grained masses in interstices of halite. Rarely it occurs as platy crystals 0.01 to 0.25 mm. MICHAEL FLEISCHER

DTA curves show endothermal breaks at 150-170, 26V280,350-360, 560-590, and 733-780". The mineral is slightly soluble in cold water and dissolves completely on boiling.

Kolovratite, which was very inadequately described, has been regarded as a doubtful species for many years. rn 1955, Guillemin examined a specimen from a locality other than the type locality and found it to be identical with vdsignidite (Am. M,i,nera|,.,4o,g42,lgss). Now, two specimens from the type locality have been restudied. The material consists of yellow, nonpleochroic, cryptocrystalline fibers. Mean index of refraction is 1.527+0.00s, birefringence is low, and extinction is parallel. Major amounts of v, Ni andzn, and minor amounts of cu, Fe and Mn were detected by r+ay fluorescence. A quantitative r-ray fluorescence analysis of 2l mg gave: zno 15%, Nio 12/6 and,yzor l2To, all accurate to within 25/6 of the amount present. It is concluded that kilovratite is a hydrous zinc-nickel vanadate or possibly a silicovanadate. strongest lines in the r-ray powder pattern are (for CuKa): 11.6 (s), 5.83 (s), and 3.88 (s). J. A.
