摘要
对东坪金矿围岩蚀变特征及蚀变与金矿化的关系进行了研究,预测了矿区可以找到新矿体的区段,并认为接触带应是矿化中心地带。含金的围岩蚀变主要是钾长石化、硅化和黄铁矿化,是寻找金矿体的蚀变岩标志,也是金矿体存在的重要特征。
The wallrock alteration characteristics and the relationship between wallrock alteration and gold metallization are studied. The regions where new ore bodies are possibly explored were prognosticated for further prospecting. The contact zone is thought to be the center zone of gold metallization. Types of Au-bearing wallrock alteration are principally potassium feldsparization, silicification and pyritization. Those are also prospecting criteria for alteration rock signal, and also the important characteristics of the existence of gold orebodies.
