| 摘 要： | 结合Au-Ag-Te三元系的实验矿物学结果，对我国金驹山 、银坑山、归来庄和驾鹿四 个金矿床中的金银碲化物矿物的共生组合特征进行了研究，并阐明了金银碲化物矿物在时空 关系上的共生组合和禁生关系特征。研究表明，金银碲化物是该类型金矿床中最重要的一类 矿物，其产出的种类和数量取决于成矿体系溶液中Au、Ag、Te元素的浓度及其含量比值；而 成矿体系中碲金银矿、碲银矿等低温同质多像变体的存在，反映了该类型矿床形成于成矿温 度和压力较低的环境条件下。

| Abstract: | The paragenetic association of Au-Ag tellurides in Jinjushan, Yinkengshan, Guil a izhuang and Jialu gold deposits has been studied based on the experimental resul ts in Au-Ag-Te ternary system. The space and time paragenetic association of Au-Ag tellurides and their non-paragenetic relationship have been r evealed as well. The experiments show that Au-Ag tellurides are the most import a nt minerals in this kind of gold deposits. The species and quantity of these min erals are controlled by the concentrations of Au, Ag, Te elements and their rati os in solutions of mineralizing system. The existence of petzite and hessite as low-temperature isomorphic modifications indicates that this kind of deposits h as been formed in the low temperature and low pressure environment . |
