摘　　要：归纳总结了物化探方法在460铀钼矿床勘查中的应用效果。重点阐述了激电中梯、高精度磁测和重力测量等方法在查明断裂构造、火山构造及次流纹斑岩体分布特征中的应用效果;通过钻探手段对活性炭测量、伽玛测量、铀量测量及土壤次生晕测量等方法圈定的矿致异常进行查证,取得了明显的找矿效果。在综合分析研究物化探找矿方法效果的基础上,进一步优化了找矿方法组合。This paper summarized the application effect of geophysical and geochemical survey method in uranium - molybdenum deposit 460. It put stress on illustrating the effects of induced current middle gra- diant, high precision magnetic survey and gravity survey method to identify the distribution features of fracture, volcano stucture and sub - rhyolite porphyry. Through verifying the mineralization caused a- nomaly which measured by activated charcoal, gamma, uranium content and secondary halo in soil with borehole, good prospecting result was achieved. Based on the above appliocation effect, the paper pres- ented some helpful prospection method combination.
