摘　　要：综合分析红石地区燕山晚期的热液蚀变作用,探讨不同期次、不同类型的蚀变及交代蚀变岩与金、银矿化之间的关系;同时对断裂蚀变带的含矿性进行研究。结果表明,第二、三期交代蚀变岩的形成与金、银矿化密切相关。空间上,北西向和北东向断裂蚀变带中易成金,南北向和东西向断裂蚀变带中易成银;垂向上,金银矿多分布于多金属硫化物蚀变带中。Through integrative analysis on the hydrothermal alteration, the paper talks about the relationship between alteration of different terms and types and the mineralization of Au-Ag; and investigates ore-bearing ability of fault alteration zones. The result shows that relationship between the aherated rocks of second-third terms and the mineralization of Au-Ag is the most important. In spatial, the fault of north-west and north-east is easy to be Au mineralization, the fault of north-south and west-east is easy to be Ag mineralization; In vertical, ores of Au-Ag are often found in the alteration of sulfide of multi-metal.
