| 摘 要： | 为了考查电磁法在探测深部金属矿及地质构造方面的实际效果,用可控源音频大地电磁法分别在埋深为500 m和1 100 m的两个已知隐伏铁、铜矿体上进行了实验工作。实验结果表明地电异常显示了矿体、断层以及岩层接触带的分布。在矿体埋藏深度小于500 m、矿层较厚时,地电异常十分明显;若矿体埋藏深度大于1 000 m,地电异常主要反应了控矿、容矿构造。

| Abstract: | To examine the actual result of the electric-magnetic method in detecting deep metallic ore deposits and structures,the authors conducted two tests in two known buried iron and copper ore deposits by using Controlled Source Audio-frequency Magnetotelluric Method(CSAMT).The two known ore bodies have the buried depths of about 500 m and 1 100 m,respectively.The results of the tests show that the geoelectrical anomalies can indicate the distribution of ore bodies,faults and lithologic contact zones.When the bu... |
