Carbonaceous - Calcium - Uranium Deposits Are Deposited on the Crevice Rocks in the Oxidation Zone of a Hydrothermal Uranium Deposit in Gansu, China. The mineral is fine granular, light yellow-green, no cleavage, the proportion of 2.83. In the long-wave ultraviolet light, strong green fluorescent hair. Trace chemical analysis results: Na_2O9.29%, CaO9.30%, UO_346.71%, CO_218.50% (TG), H_2O ~ + 15.20% and a small amount of K_2O, MgO, MnO and so on. X-ray powder analysis of strong lines: 13.054 (60), 7.931 (55), 5.697 (100), 5.254 (75), 5.182 (65), 4.332 (70), 4.174 (60), 3.688 (100). Cell parameters: a = 13.0215A (α = 86.844 °) or α = 17.9012A, c = 23.7631A. Monoaxial crystal, positive light, Ne = 1.546, No = 1.521.
