摘　　要：马鬃山地区位于北山金成矿区东段,已发现金矿均与航空伽马能谱测量铀异常有关。经实地查证,石板墩航放铀异常处于墩墩山岩体与三个井群的接触带部位,受东西向两条碎裂石英脉控制,铀含量最高达18×10^(-6),已经超过10×10^(-6)工业边界品位;金含量在(0.5~6.16)×10^(-6),也已达到工业品位,铀金具有明显伴生特点。因此,应用放射性测量方法,为在马鬃山地区寻找铀金矿产提供了快速有效方法。Mazong Mountain is located in the eastern section of the Beishan gold mining area. Gold deposits are associated with anomalies detected by airborne radioactivity measurements,which are located in uranium anomalous edge gradient belt. By using the radioactivity measurement method,the authors found that the Shibandun uranium anomaly is located in the contact zone between Dundunshan magma mass and Sangejing groups and is controlled by two EW-trending broken quartz veins. The U content is higher than 18 × 10^-6 in Shibandun uranium anomaly and exceeds 10 × 10^-6 industrial boundary grade standard. Trough revealed that the uranium and gold have association characteristics. Gold content is（ 0.5 ～ 6.16） × 10^-6,and has reached the industrial grade. Therefore the radioactive measurement method is a rapid and effective method in the search for uranium and gold deposits in Mazong Mountain area.
