摘　　要：在大官厂铀钼矿区北带东部的已知剖面开展氡气和金属活动态测量方法的有效性试验,证实在隐伏铀钼矿体上方存在明显的氡气异常和铀钼活动态异常。利用该方法对矿区北带西部进行找矿预测,对综合异常开展钻探验证,发现了隐伏铀钼矿体,证实氡气测量和金属活动态测量是寻找隐伏铀钼矿床的有效方法。The effectiveness of radon gas and metal mobile state measurement was tested along the known profile in eastern part of the north belt of the Dagnanchang uranium-molybdenum ore district, and the result shows that obvious radon gas anomalies and uranium- molybdenum mobile state anomalies exist over the concealed uranium-molybdenum ore body. Using this method, the authors made ore- prospecting prognosis in the western part of the north belt, followed by drilling verification of the integrated anomalies. As a result, concealed uranium-molybdenum ore bodies were discovered, which proves the effectiveness of radon gas measurement and metal mobile state measurement in search for concealed uranium-molybdenum deposits.
