【摘要】 对花山花岗岩体中金矿的围岩蚀变特征和围岩蚀变与金矿化的关系进行了研究,并建立了蚀变模式。含金的围岩蚀变主要是钾长石化、钠长石化、硅化和黄铁矿化,是寻找金矿体的蚀变标志,也是金矿体存在的重要特征。认为在豫西寻找金矿床,应拓展到花岗岩体中。更多还原

【Abstract】 The wall rock alteration characteristics and the relationship between wallrock alteration and the alteration model are set up in the paper. Types of Au-bearing wallrock alteration are principally potassium feldspathization, sodium feldspathization, silicification and pyritization. Those are alteration rock indicators for prospecting and important characteristics of the occurrence of gold ore bodies. The gold deposit prospecting area in Western Henan should be further extended into granite body.更多还原
