摘要
研究区位于摩天岭岩体北部,属于雪峰山-摩天岭铀成矿带的摩天岭成矿亚带。为了探测含矿俾门断裂带在深部的延伸情况,在研究区开展了音频大地电磁(AMT)测量。测量结果显示,俾门断裂带切割深、规模大,总体产状倾向南西,倾角为50°~80°,走向为320°~330°,沿走向和倾向膨胀收缩、扭动弯曲明显,在地表的宽度为190m^300m,深部的宽度为200m^400m。断裂带内的热液活动具有南弱北强的特点。根据区域铀成矿规律,预测了两处铀成矿有利地段,为下一步铀矿勘查工作提供了重要依据。
The study area is located in the Motianling inferior uranium metallogenic belt,which belongs to the MotianlingXuefengshan uranium metallogenic belt.In order to detect the deep extension of Bi-Meng fault zone,the audio frequency magnetotelluric(AMT)measurement has been carried out.The measurement results show that the Bi-Meng fault zone extends to great space in horizontal and vertical direction,the width is 190m^300min surface and 200m^400min deep.It incline towards southwest,which has dip angle of 50 degrees to 80 degrees and strike angle of 320 degrees to 330 degrees.Along the strike and dip direction,there is wide variety in scale and shape.It also reveal that the strong hydrothermal activity in the northwestward and weak in southeastward.According to regional metallogenic regularity of uranium,two favorable uranium mineralization area have been predicted,which propitious to explore uranium deposit for the next step.
