| Abstract: | This paper deals with 3 effective geophysical prospecting methods for the Roigêuranium ore field.The application of total gamma survey scan to the determination of range of reconnaissance narrows down the prospecting area.Gamma spectrum survey is applied to the evaluation of shallow anomalies in well exposed bedrock area with total gamma anomalies.Radon emanation survey is applied to the evaluation of deep anomalies in the poorly exposed bedrock and shallow coverage area with total gamma and gamma spectrum anomalies.The three methods in combination with hydrochemical survey and geological data provide scientific basis for deep prospecting in the Roigêuranium ore field. |
