摘　　要：采用地面伽马能谱测量、土壤地球化学剖面测量及音频大地电磁测量等物化探方法,在沽源县西湾浅覆盖地区开展铀矿勘查工作。浅表通过地面伽马能谱及土壤地球化学剖面测量,探寻铀矿化相关的异常信息;在重点异常地段深部开展音频大地电磁测量,剖析了深部断裂,解释了深部潜流纹岩体形态;结合地质情况,对物化探异常进行综合分析,通过钻探对异常部位进行揭露,发现了隐伏铀矿化异常,为该区进一步找矿指明了方向。Based on geophysical and geochemical methods such as ground gamma-ray spectrometric survey,soil geochemistry profile survey and audio frequency magnetotelluric sounding survey,the authors investigated the uranium deposits in the shallow coverage areas in Xiwan area of Guyuan County. The surface anomaly information related to uranium mineralization was revealed by the ground gammaray spectrometric survey and soil geochemistry profile survey. The faults and the morphology of subvolcanic rhyolite were analyzed by audio frequency magnetotelluric sounding survey in the anomaly sectors. The blind uranium orebody was found,followed by drilling verification of the integrated anomalies. The conclusion of prediction has some indication significance for further ore-prospecting work in this area.
