锌黝铜矿是黝铜矿的一种新变种矿物,至今尚未见到过天然的锌黝铜矿的研究和报导。锌黝铜矿电子探针定量分析结果:Cu33.10%,Zn11.27%,Ag0.79%,Fe1.22％,Sb27.74％,Pb1.51％,S24.97％,总量100.60％。它的化学式为: (Cu,Zn,Ag,Fe)_(12.03)(Sb,Pb)_(3.92)S_(13) X射线分析表明锌黝铜矿为立方晶系,空间群I43m,与黝铜矿相同,而晶胞参数a_0=10.382(?)要比黝铜矿a_0=10.327(?)要大。锌黝铜矿为棕灰的微带青色,金属光泽。粒径0.13～0.17mm。VHN_(20g)=210(Kg/mm～2)。相当于莫氏硬度4.1。反射率(λ,R′)为:405nm,31.4;436nm,30.5;480nm,29.7;526nm,30.4;546nm,30.4;589nm,29.6;656nm,28.6;700n,26.2。等能光源(SE)反射色颜色指数:R′_(vis)30.6,X0.3265,Y0.3386,λ_a503,Pe0.0213。锌黝铜矿产于浙江省天台县浒南银铅锌矿床中。
Zinc tetrahedrite is a new variety of tetrahedrite minerals, so far have not seen the natural zinc tetrahedrite research and reports. Quantitative analysis of zinc tetrahedron electron probe results: Cu33.10%, Zn11.27%, Ag0.79%, Fe1.22%, Sb27.74%, Pb1.51%, S24.97%, the total amount of100.60% . Its chemical formula is: (Cu, Zn, Ag, Fe) _ (12.03) (Sb, Pb) _ (3.92) S_ (13) X-ray analysis shows that the zinc tetrahedrite is cubic crystal system, space group I43m, The copper deposits are the same, while the unit cell parameter a_0 = 10.382 (?) Is larger than the tetrahedrite a_0 = 10.327 (?). Zinc tetrahedron brownish gray microstrip cyan, metallic luster. Particle size 0.13 ~ 0.17mm. VHN_ (20g) = 210 (Kg / mm ~ 2). Equivalent to Moh’s hardness 4.1. Reflectance (λ, R ’): 405 nm, 31.4; 436 nm, 30.5; 480 nm, 29.7; 526 nm, 30.4; 546 nm, 30.4; 589 nm, 29.6; 656 nm, 28.6; 700 n, 26.2. Equivalent light source (SE) reflection color index: R ’_ (vis) 30.6, X0.3265, Y0.3386, λ_a503, Pe0.0213. Zinc tetrahedrite mine in Zhejiang Tiantai Hunan silver lead-zinc deposits.
