1983年,ZhitomirsKii等人在实验室条件下合成了四方晶体Bi16CrO27和立方晶体Bi38CrO60.它们在自然界首次发现于中国陕西省洛南县驾鹿金矿床中,分别被命名为铬铋矿(Bi16.006Cr0.997O27)和驾鹿矿(Bi38.008Cr0.996O60).驾鹿矿较铬铋矿形成较晚,其共生、伴生矿物有黄铜矿、自然金、碲金矿、含氧金矿物、石英等.常呈不规则粒状集合体,偶见<0.05mm立方体微晶,棕黑色,金属光泽;平均维克硬度Hv=232.78kg/mm2,平均摩氏硬度Hm=4.15;实测密度D=14.10(3)g/cm3,计算密度Dx=14.08(2)g/cm3,折射率n=3.14(3).采用2种电子探针进行波谱定量分析的成分及计算的化学式分别是:①EPM8100分析的结果:w(Bi2O3)为98.854%、w(CrO3)为1.111%,总和为99.965%;化学式为Bi38.009Cr0.995O60;②CAMEBAX-SX51分析的结果:w(Bi2O3)为98.862%,w(CrO2)为1.112%,总和为99.974%;化学式为Bi38.008Cr0.996O60.均可写为Bi38CrO60.2种仪器测定的结果非常接近,说明所测定的化学成分和计算的化学式是十分可靠的.X-射线粉晶分析主要强线d(I)(hkl)分别为:0.3215(100),(310);0.27211(72),(321);0.17145(40),(530);0.1696(30),(600);0.1651(30),(611);0.1608(30),(620);0.29411(25),(222);0.3596(22),(220);0.2171(20),(332);0.1503(20),(631);0.1996(18),(
In 1983, ZhitomirsKii et al synthesized tetragonal Bi16CrO27 and cubic crystal Bi38CrO60 under laboratory conditions, and they were first discovered in nature in the Jiaolu gold deposit of Luonan County, Shaanxi Province, China, and were named as Bi 16.006Cr0 .997O27) and go deer mine (Bi38.008Cr0.996O60) .Drines deer ore than the formation of bismuth ore later, its symbiosis, associated minerals are chalcopyrite, natural gold, tellurium gold, oxygen-bearing gold minerals, such as quartz Often irregular granular aggregates, occasionally <0.05mm cubic crystallite, brown black, metallic luster; The average Vickers hardness Hv = 232.78kg / mm2, the average Mohs hardness Hm = 4.15; The measured density D = 14.10 (3 ) g / cm3, the calculated density Dx = 14.08 (2) g / cm3, the refractive index n = 3.14 (3). The chemical composition and calculated chemical formulas of the two kinds of electronic probes were: ①EPM8100 analysis results: (Bi2O3) is 98.854%, w (CrO3) is 1.111%, the sum is 99.965%; chemical formula is Bi38.009Cr0.995O60; ②CAMEBAX-SX51 analysis results show that the w (Bi2O3) is 98.862% and the w %, The sum of 99.974%; chemical formula for the Bi38.008Cr0.996O60. Can be written as Bi38CrO60.2 kinds of instruments measured results are very close, indicating that the measured chemical The chemical formulas for fractionation and calculation are quite reliable. The main strong line d (I) (hkl) of X-ray powder analysis is 0.3215 (100), (310), 0.27211 (72), (321), 0.17145 0.1696 (30), (611); 0.1608 (30), (620); 0.29411 (25), (222); 0.3596 (22), (220) ; 0.2171 (20), (332); 0.1503 (20), (631); 0.1996 (18), (
