水硒铀钡矿为黄色,0.4mm 长的斜方晶体。a=7.25,b=16.84,c=7.084。空间群:Pncm。粉晶线条强度8.39强(020),7.29强(100),3.55中强(210),6.68中等(110)。(100)解理完整。d 测量值=4.88;d 计算值=4.92。二轴晶,负光性:2 V=35°。色散强 r>v-n_g=1.805,n_m=1.798,n_p=1.720。定量分析结果如下:SeO_2=16.8%,BaO=10.8%,UO_3=64.5%,H_2O=7.1% 合计:99.2,得出分子式为:Ba(UO_2)_3(OH)_4(SeO_3)_2·3H_2O。测定了热失重曲线。此新矿物产于谬索莫瓦层状铜钴矿床中。典型标本保存在巴黎国立高等矿业学院。此矿物是根据 C.Guillemin 的名字而命名为 Guilleminte 的。
Selenium water barium ore yellow, 0.4mm long orthorhombic crystal. a = 7.25, b = 16.84, c = 7.084. Space group: Pncm. Powdered crystal line intensity 8.39 strong (020), 7.29 strong (100), 3.55 strong (210), 6.68 medium (110). (100) cleavage complete. d measured = 4.88; d calculated = 4.92. Biaxial crystal, negative light: 2 V = 35 °. Dispersion strong r> v-n_g = 1.805, n_m = 1.798, n_p = 1.720. Quantitative analysis results are as follows: SeO 2 = 16.8%, BaO = 10.8%, UO 3 = 64.5%, H 2 O = 7.1% Total: 99.2, and the formula is Ba (UO 2) _3 (OH) _4 (SeO_3) _2 · 3H_2O. The thermogravimetric curve was determined. This new mineral is produced in the pyramidal samoa layered copper-cobalt deposit. Typical specimens are stored in the Paris National Institute of Advanced Mining. This mineral is named Guilleminte under the name C.Guillemin.
