| 摘 要： | 我国含碲化物的金矿床主要有４种类型，太古宙花岗－绿岩地体中的含金石英脉型矿床、元古宙火山岩中的蚀变构造岩型金矿床、中－新生代火山岩中的浅成低温热液金银矿床，与花岗岩有关的金矿床。总结了我国已发现的碲化物的光学性质，硬度及其共生组合特征，列出了主要碲化物的电子探针定量分析结果，最后讨论了碲化物形成的某些地球化学习性，碲化物总是与自然金一起形成于矿化的晚期，这表明它与金有某些一致的地球化学习性，并可能

| Abstract: | There are mainly four types of telluride bearing gold deposits in China, namely, gold bearing quartz vein type in Archaeozoic granite greenstone terrain, altered tectonite type in Proterozoic volcanic rocks, epithermal gold silver deposits in Meso Cenozoic volcanic rocks and gold deposits related with granite. The optical properties, hardness and associated characteristics of the found tellurides in China are summed up. The results of quantitative analysis on the main tellurides by electron microprobe are listed. Some geochemical behaviors of tellurides are discussed. It shows that telluride always occurrs in late mineralization with native gold, which indicates that it has some identical geochemical behaviors with gold and can form complex with gold to be transported by hydrothermal solution. |
