摘要
含锗锡硫钒铜矿是硫钒铜矿的含锗锡变种。它产于四川省白玉县呷村银多金属矿床中,反光显微镜下为淡柠檬黄色,形态呈正方形、长方形及不规则状。粒度一般为0.01—0.1mm,最大为0.3mm。显微硬度Hv=137.8kg/mm2,相当于HM=3.49。反射率:589nm 31.54%。主要化学成分为:Cu 52.29—54.71%,S 30.59—32.49%,V 5.70—6.50%,Ge 4.3—6%,Sn2.43—3.56%,还含微量Zn、Fe、As、Sb、Bi等。简化式为:Cu3(V,Ge,Sn)S4。矿物为等轴晶系,ao=10.66,V=1211.36,空间群为P43m,Z=8。
Ge-, Sn-bearing sulvanite, a variety of sulvanite, occurs in the Gacun Agbearing polymetallic ore deposit, Sichuan Province. It is normally square, rectangular or irregular in form and light lemon yellow in color; its grain sizes are commonly 0.01-0.1 mm with the greatest being 0.3 mm. Microhardness 137.8kg/mm^2, equivalent to 3.49 on Mohs hardness scale; reflectance 31.54% (589 nm). The main chemical components are Cu 52.29-54.71%, S 30.59-32.49%, V 5.70-6.50%, Ge 4.3-6% and Sn 2.43-3.65%, with trace amounts of Zn, Fe, As, Sb and Bi, giving a simplified formula of Cu_3 (V,Ge, Sn) S_4. The mineral is of cubic system, a_0=10.66, V=1211.36~3, with space group P3m.
