Kuliginite is a new iron-magnesium hydroxychloride mineral with the ideal formula Fe3Mg(OH)6Cl2 from the Udachnaya East kimberlite, Yakutia, Russia. It occurs as green prismatic-bipyramidal crystals (0.2–0.5 mm) and fills cavities and veins in several units of kimberlites together with iowaite, gypsum, calcite, halite, barite, and celestine. It is trigonal, with R3̅ space group. Kuliginite has imperfect cleavage on {101̅1}. The spinel-like crystal structure of kuliginite is also typical for several copper minerals of the atacamite group with common formula Cu3M(OH)6Cl2; kuliginite can be regarded as a Fe2+ analog of tondiite [Cu3Mg(OH)6Cl2. The occurrence of the kuliginite + iowaite + gypsum assemblage has implications for the interpretation of low-temperature (below 100°C) hydrothermal processes and alteration of kimberlite by hydrothermal fluids/brines, as well as for transport of metals in Cl-bearing solutions. This secondary hydrothermal mineral assemblage formed much later than the kimberlite groundmass minerals. Kuliginite contains inclusions of iowaite indicating their simultaneous crystallization.

A new mineral beshtauite, (NH4)2(UO2)(SO4)2⋅2H2O, was found in the oxidation zone of the Beshtau uranium deposit, Mount Beshtau, Stavropol region, Northern Caucasus, Russia, and named after the locality. It is associated with rozenite, gypsum, lermontovite, and older marcasite, pyrite, halloysite, and opal. Beshtauite occurs as well-shaped short-prismatic crystals up to 0.1 x 0.15 x 0.2 mm, their clusters and crusts up to 0.5 mm across growing on marcasite. Beshtauite is transparent, light green. The luster is vitreous. The mineral fluoresces strongly yellow-green under both short- and long-wave UV irradiation. It is brittle. The Mohs hardness is ca. 2. Cleavage was not observed. Dcalc is 3.046 g/cm³. Beshtauite is optically biaxial (+), α = 1.566(3), β = 1.566(3), γ = 1.592(3), 2Vmeas < 10°. The chemical composition (wt%, electron microprobe data, H2O by difference) is: (NH4)2O 10.33, UO3 53.21, SO3 29.40, H2Ocalc 7.06, total 100.00. Content of (NH4)2O was calculated from measured nitrogen content: 5.56 wt% N. The empirical formula, calculated on the basis of 12 O apfu, is (NH4)2.12U0.99S1.96O9.91 (H2O) 2.09. Beshtauite is monoclinic, P21/c, a = 7.7360(8), b = 7.3712(5), c = 20.856(2) Å, β = 102.123(8)°, V = 1162.76(19) Å3, Z = 4 (from single-crystal X-ray diffraction data). The strongest reflections of the X-ray powder pattern [d (Å), I(hkl)] are: 6.86, 100(011, 102); 5.997, 19(012); 5.558, 15(102); 5.307, 36(111,110); 5.005, 35(013,112); 3.410, 38(114,204,106); 3.081, 24(016); 2.881, 20(106,123). The crystal structure was solved by direct methods and refined on the basis of 2677 independent reflections with I > 4σ(I) to R1 = 0.093. The structure is based upon [UO2(SO4)2(H2O)]2- layers consisting of corner-sharing UO6 (H2O) pentagonal bipyramids and SO4 tetrahedra. The layers are coplanar to (102) and are linked via hydrogen bonding that involve interlayer NH4+ ions and H2O molecules. Beshtauite is important indicator mineral: its presence can be considered as an evidence of transportation of U6+ in nature in forms of mobile complexes of uranyl cation with ammonia or polyamines.

Césarferreiraite, Fe2+Fe23+(AsO4)2(OH)2·8H2O, is a new laueite-group mineral (IMA 2012-099) of triclinic symmetry, from Eduardo pegmatite mine, Conselheiro Pena municipality, Minas Gerais, Brazil. Intimately associated minerals are pharmacosiderite, scorodite, and earlier arsenopyrite, and probably césarferreiraite replaces the latter. It occurs as fibrous-to-tabular aggregates up to 2 mm. Single crystals, up to 10 μm long with a thickness of about 1-2 μm, are elongated along [001] and flattened on (100). The fibers have almost rectangular cross-section apparently bound by the {100} and {010} pinacoid forms. Color and streak are pale to greenish yellow. Luster is vitreous; individual crystals are transparent and masses are translucent. Cleavage is distinct, presumably on {010} and {100}. Calculated density is 2.934 g/cm³. The mineral is biaxial (+), n (min) = 1.747(3), n (max) = 1.754(3) (589 nm). IR spectrum of césarferreiraite is unique and can be used for the identification of the mineral. Chemical composition (n = 4, WDS, calculated for the condition Fe2+:Fe3+ = 1:2, H2O for the ideal structural formula, wt%) is: FeO 11.50, Fe2O3 25.56, CaO 15.41, As2O5 33.51, H2O 26.01, total 100.12. The empirical formula (based on 18 O apfu) is Fe0.982+Fe1.963+ [(AsO4)1.79(PO4)0.31](OH)1.52·8.08H2O. The strongest eight X-ray powder-diffraction lines [d in Å(I)(hkl)] are: 9.85(95)(010), 6.35(100)(001), 3.671(29)(...), 3.158(32)(...), 2.960(39)(...), 2.884(35)(...), 2.680(29)(...), and 2.540(23)(...). Unit-cell parameters refined from powder data indexed by analogy with related laueite-group minerals (space group: P...) are: a = 5.383(2), b = 10.363(3), c = 6.878(2) Å, α = 96.42(4), β = 109.19(3), γ = 102.30(2)°, V = 347.1(2) ų, and Z = 1. Gladstone-Dale compatibility is -0.020 (excellent). Césarferreiraite is the arsenate analog of ferrolaueite. [ABSTRACT FROM AUTHOR]

The measured density is 3.25(2) g/cm3; the calculated density is 3.275 g/cm3. The mineral is biaxial (+), α = 1.661(5), β = 1.673(5), γ = 1.703(5), 2Vmeas = 70(10)°, 2Vcalc = 65.6°. The IR spectrum confirms the presence of H2O. The Mössbauer spectrum shows the presence of two sites for Fe2+ and one site for Fe3+ occupied in the ratio Fe12+:Fe22+:Fe3+ = 39:55:6. The chemical composition is as follows (electron microprobe, H2O determined by gas chromatography of ignition products, Fe apportioned between FeO and Fe2O3 based on Mössbauer data, wt%): MnO 29.21, FeO 21.74, Fe2O3 1.54, P2O5 34.59, H2O 12.6, total 99.68. The empirical formula, based on 11 O apfu, is H5.78Mn1.70Fe1.252+Fe0.083+P2.015O11. The strongest lines of the powder X-ray diffraction pattern [d, Å (I, %) (hkl)] are: 5.08 (43) (020), 4.314 (28) (002, 210), 3.220 (100) (221, 202), 3.125 (25) (122), 2.756 (35) (103, 230), 2.686 (25) (222, 113), 2.436 (22) (123), and 2.233 (23) (411, 331). The crystal structure is solved (R1 = 0.0176). Correianevesite is orthorhombic, space group Pbna, a = 9.4887(2), b = 10.1149(2), c = 8.7062(2) Å, V = 835.60(3) Å3, Z = 4.
