| 摘 要： | 热液金矿床总是伴随着围岩蚀变,研究围岩蚀变对金矿勘查具有重要意义。总结不同类型热液金矿发现,与热液金矿密切相关的围岩蚀变主要有硅化、钾长石化、钠长石化、碳酸盐化、绿泥石化、绢英岩化等;重点分析讨论了硅化、钾长石化、钠长石化、碳酸盐化的特征、形成机理及其与金矿化之间密切关联的内在原因,同时也对热液金矿蚀变的分带性进行了讨论。

| Abstract: | The hydrothermal gold deposit is always accompanied by wall rock alteration, which is of great significance for gold explora-tion. It is found that the wall rock alterations closely associated with the hydrothermal gold deposit include silicification, potassic altera-tion, albitization, carbonation, chloritization and propylitization, as shown by summary of different types of hydrothermal gold deposits. This paper has emphatically discussed the geochemical characteristics of silicification, potassic alteration, albitization, and carbonata-tion, and the reasons why gold mineralization is associated closely with these alterations. Alteration zoning of hydrothermal gold deposits is also briefly discussed. |
