摘要
在五圩锑矿中发现了含银锑黝铜矿 ,粒径 1mm～ 3mm,与其共生的矿物有 :脆硫锑铅矿、方铅矿、黄铁矿、闪锌矿和辉锑矿。含银锑黝铜矿呈银灰色 ,金属光泽 ,条痕暗灰色 ,无解理 ,H=4～ 4.5 ,ρ=1.86 kg/cm3,显微镜下含银锑黝铜矿呈灰色 ,其均质性和反射率采用改装 MPV- 3型显微光度计测定 ,仪器内标使用硅砂和 (W,Ti) C;此外 ,分别采用
Ag-bearing antimony fahlor of 1 mm^3 mm in dia meter was found in Wugu antimony ore deposit. Associated minerals are Jamesonite, gal en, pyrite, sphalerite, antimonite. On the hand samples Ag-antimony fahlore is silver-grey in colour, with metallic luster, dark-grey streak, and withou t cleavage. H=4~4.5, ρ=1.86 kg/cm 3. Under the microscope the Ag-tetrahedrite shows grey colour. The isotropy and reflectivity were determined with modified MPV-3 microscope photometer by using silicon carborund and (W, Ti) C as standar ds. Chemical composition of Ag Sb-tetrahedrite was determined by electron microprobe and X- ray analysis was also conducted.
