摘要
钾是含金热液最主要的组分之一。热液在沿着裂隙通道的活动中,能对围岩产生明显的钾交代蚀变。钾异常在成因上和空间上与金矿化的密切关系,对金矿的找矿勘探和成矿预测具有重要意义。勘查实践证明,还可用γ能谱法现场探测获得钾异常。这种简便的勘查金的新技术方法值得推广使用。
Potassium is one major component of gold-bearing hydrothermal solution. Hydrothermal processes are able to produce significant potassium metasomatism for country rocks along fracture channel. Potassium anomalies are
closely associated with gold mineralization in genesis and in space and is significant to prospecting and prognosis
of gold deposits. Gamma-ray spectrommetric survey is the best method to detemine potassium anomalies as comparing with others based on our practice.
