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， 并可能一起形成配合物被热液搬运。
There are mainly four types of gold deposits containing telluride in our country: gold-bearing quartz vein type deposits in the Archean granitic-greenstone terrane, altered tectonic-rock type gold deposits in the Proterozoic volcanic rocks, Meso-Cenozoic volcanic rocks Shallow epithermal gold and silver deposits, granite-related gold deposits. The optical properties, hardness and symbiosis characteristics of tellurides found in our country are summarized. The results of quantitative analysis of electron probe of the main tellurides are listed. Finally, we discuss some of the geochemical behavior of telluride formation, which is always formed with mineral gold in the late stages of mineralization, suggesting some consistent geochemical behavior with gold and possibly together forming a complex It is transported by hydrothermal fluid.
