浅析蚀变岩型金矿床的某些蚀变特征与金矿化的关系——以东湾金矿为例

On the Relation of Au Mineralization with Wallrock Alteration for Altered Rock Type Gold Deposits——By the Example of the Dongwan Au Deposit

通过对蚀变岩型金矿床蚀变现象观察与分析,从金元素地球化学性质和行为入手,探讨金矿化与硅化、黄铁矿化蚀变的内在联系。硅化及黄铁矿化蚀变越强金矿化一般越好,但有硅化与黄铁矿化蚀变不成矿的现象也确实存在。在成矿有利的地球化学省内,可以把硅化与黄铁矿化蚀变作为寻找金矿床的标志。

Study indicates that Au mineralization is in close relationship with silicification and pyritization for altered rock type gold deposits.These wallrock alterations may be used as prospecting criteria for the altered rock type gold deposits.
