硫碲铋铅金矿(AuPb2BiTe2S3)是1991年国际新矿物及矿物命名委员会(CNMMNIMA)批准的新矿物,产于美国科罗拉多(Colorado)州的巴克霍恩(Buckhoun)矿山。我们于1986年发现了该矿物,但呈报CNMMNIMA晚于美国。我国的硫碲铋铅金矿产于河南灵宝出岔-乱石和桐沟两个石英脉型金矿。该矿物为柱板状晶体,粒径0.03~0.2mm,黑色,一组解理发育,金属光泽。显微硬度为64~129kg/mm2,(负荷10g),反射色为灰色,微带蓝色色调,非均质性明显,无内反射,以等能光源(SE)对R1和R2计算的颜色指数分别为:x0.323,y0.326,Y%42.69,λd480,Pe%0.04;和x0.326,y0.326,Y%43.70,λd476,Pe%0.03。电子探针分析结果为:CU0.02,Au16.96,Ph35.34,Bi15.93,Te20.79,S8.21。化学式为:Au1.03Ph2.04Bi0.91Te1.95S3.06,斜方晶系,a=0.41,b=1.25,c=0.95nm,V=0.487nm3。理论比重Dx=7.94。
The bismuth-lead-bismuth gold mine (AuPb2BiTe2S3) is a new mineral approved by the 1991 International Commission on Nomenclature of Minerals and Mineralogy (CNMMNIMA) and is produced at the Buckhoun mine in the state of Colorado, USA. We discovered the mineral in 1986 but reported CNMMNIMA later than the United States. China’s sulfur-telluride bismuth-lead-gold mine is produced in Henan Lingbao bifurcation - rock and Tonggou two quartz vein gold mine. The minerals are columnar crystals, particle size 0.03 ~ 0.2mm, black, a group of cleavage development, metallic luster. Microhardness 64 ~ 129kg / mm2, (load 10g), the reflection color is gray, the blue color tone of the microstrip, the obvious heterogeneity, no internal reflection, The indices are: x0.323, y0.326, Y% 42.69, λd480, Pe% 0.04; and x0.326, y0.326, Y% 43.70, λd476, Pe% 0.03. Electron probe analysis results were: CU0.02, Au16.96, Ph35.34, Bi15.93, Te20.79, S8.21. Chemical formula: Au1.03Ph2.04Bi0.91Te1.95S3.06, orthorhombic system, a = 0.41, b = 1.25, c = 0.95nm, V = 0.487nm3. Theoretical weight Dx = 7.94.
