【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。更多还原

【Abstract】 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 orebearing ability of fault alteration zones.The result shows that relationship between the alterated 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.更多还原
