Abstract

Belogubite CuZn(SO4)2 ⋅ 10H2O, a new mineral of the chalcanthite group, is found in the Gai (Gaiskoe) massive sulfide deposit, South Urals, Russia. This mineral forms aggregates of blue grains up to 1 mm. It is optically biaxial (–), np = 1.512(2), nm = 1.525(2), ng = 1.531(2), 2V = 70(10)°. The chemical composition of the holotype sample is as follows (wt %): 1.12 MgO, 0.10 MnO, 3.15 FeO, 8.98 CuO, 18.02 ZnO, 32.49 SO3, and 36.75 H2O, total 100.61. The empirical formula is (Cu0.55Zn0.45)Σ1.00(Zn0.64Fe0.22Mg0.14Mn0.01)Σ1.01S1.99O7.98 ⋅ 10.02H2O. The crystal structure of belogubite is studied using the single crystal method, R = 0.016. The mineral is triclinic, P\({{\bar {1}}}{\text{.}}\) The unit cell parameters are: a = 6.2548(1), b = 10.6112(2), c = 6.0439(1) Å, α = 82.587(1), β = 109.625(1), γ = 104.848(1)°, V = 364.81(1) Å3, and Z = 1. The strongest reflections of the powder XRD pattern [dmeas., Å (I, %) (hkl) are: 5.73 (35) (100), 5.576 (47) (–110), 4.873 (100) (–111), 3.907 (31) (021), 3.719 (45) (0 –21), 3.229 (27) (111), 2.915 (25) (–221), and 2.684 (26) (130).
