The paleo-Shibei area has a good geological background of uranium mineralization, and some mineralization spots and uranium anomalies have been found. The previous work was mainly focused on the surrounding and shallow parts of the mineralization spots, and the evaluation of the overall metallogenic environment and the understanding of the deep metallogenic conditions in the study area were insufficient. The authors briefly introduced the working methods of soil radon, ground gamma energy spectrum and audio frequency magnetotelluric survey, analyzed the uranium metallogenic environment in the study area by comprehensive geophysical survey, delineated the approximate position of uranium ore anomaly on the surface by carrying out soil radon and ground gamma energy spectrum survey, and found the paleo-rock back of ore-controlling fault by carrying out audio frequency magnetotelluric survey (AMT). The characteristics of the development of the fault and ore-controlling strata of Shimaoshan Group were determined, and the inferred interpretation data were verified by drilling, which provides a reference for the exploration of this type of uranium deposits.
