摘要
碲铅铋矿和自然碲产于河南省小秦岭含金石英脉矿床中。碲铅铋矿化学成分平均值(%)为:Te44.06,Bi40.24,Pb14.23,并含有微量的Ag、Au、Hg、Fe、Ni、Cu等元素。理论化学式为(Bi,Pb)_3Te_4,其中Bi>Pb。共生矿物有自然金、碲金矿、破银矿、碲铅矿、碲金银矿、碲铋矿;方铅矿、闪锌矿、黄铁矿、黄铜矿等。 自然碲反射色为纯白微带乳色,非均质性清楚,偏光色为蓝灰-棕灰色。显微硬度为H_v=85.1kg/mm^2(25g)。共生矿物有碲金银矿、碲银矿、黄铜矿等。化学成分中碲含量达98.44％,并含Ag、Cu、W、Fe、Pt等微量元素。
Rucklidgeite and native tellurium, which rarely occur in nature, have beenfound in gold-bearing quartz veins in the Xiaoqinling gold field. Electron probe analysis of rucklidgeite gives (%): Te 44.06, Bi 40.24, Pb 14.23, Sb 0.04, Ag 0.31, Au 0.09, Fe 0.04, Ni 0.04, Cu 0.02 and Hg 0.05on average. Associated minerals include native gold, calaverite, hessite, altaitepetzite, galena, sphalerite, chalcopyrite, etc. The reflected colour of the native tellurium is pure white with a creamtint. Anisotropy is distinct with a bluegrey polarized colour. H_v=85.1kg/mm^2The native tellurium is associated with petzite, hessite, chalcopyrite, etc. Electron probe analysis of the native tellurium gives(%): Te 98.443, S 0.085, Ag0.072, Cu 0.314, W 0.276, Fe 0.727 and Pt 0.092.
