【摘要】 Ｕ、Ｔｈ、Ｋ、Ｒｎ等核辐射及含量在含金地质体与非含金地质体间的差异是用放射性方法勘查金矿的地球物理和地球化学条件。大量实例表明，各种放射性方法都可在一定条件下用于金矿床勘查，并能取得良好效果。不同类型的金矿床，Ａｎ与Ｕ、Ｔｈ、Ｋ、Ｒｎ等有不同的组合关系。更多还原

【Abstract】 Differences of radioactivities and concentrations of U,Th,K,Rn between gold bearing geologic bodies and barren geological bodies are the geophysical and geochemical prerequisite to radiologlcal survey for gold deposits.many examples have shown that every kindof radiological method can be used in prospecting for gold deposits and result in favourableeffectiveness under certain conditions.Different combination retations of An,U,Th,K andRn exist in different types of gold deposits.更多还原
