摘　　要：通过测量岩石中放射性元素所发射γ射线来确定岩石中铀、钍、钾的含量,并通过分析铀、钍、钾与金矿化的关系来指导金矿找矿,它不受井下工程及设施的影响,在生产矿区的探边找盲中有较大的优势。通过在金华山矿区的找矿应用,利用γ能谱测量中钾测量道和总测量道所圈定的复合异常与矿区内已知矿体对应较好,并发现了新的可供验证的异常。The contents of U, Th and K in rock can be determined by measuring the γ-ray launch from the internal radioactive elements. The analysis on relations between the elements of U, Th , K and gold mineralization can instruct the gold deposit prospecting. It will be not affected by the underground projects and facilities and is an ad- vanced method for boundary and blind orebody prospecting. Its application in Jinghuashan mining deposit shows that, the known ore body is according very well with the complex anomaly map drawn by the value of K channel and the total channel. And new anomalies are discovered for further verification.
