摘要

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.
