| 摘 要： | 近几年,相山铀矿田的勘探表明,断层与组间界面变异部位、基底界面的复合部位是深部找矿的重要标志。针对乐家地区深部铀资源评价需要,开展了音频大地电磁法（AMT）测深工作,成功划分了组间界面和基底界面,推断了断裂构造,为该区深部资源预测提供了依据。钻探验证,AMT方法在相山地区探测深部地质结构中效果明显。

| Abstract: | In recent years, exploration in Xiangshan uranium ore field shows that the intersection of faults and the interface of different rock formation and the basement is an important sign of deep ore-prospecting. In order to evaluate deep uranium resource in Lejia district, audio magnetotelluric method（AMT） was undertaken to carry out profile investigation. With that method, we discerned the interfase of different rock formation and the basement successfully, and faults in the deep, which provides a good basis for the prediction of deep uranium resource. Drilling results show that AMT method has an obvious advantage in detecting deep geological structures in Xiangshan. |
