为推进航空瞬变电磁法在我国浅覆盖区寻找多金属矿的应用，选择在已知火山岩型块状硫化物（ VMS）矿区开展航空瞬变电磁法测量试验，结果显示：反演电阻率断面图中低阻异常与勘探剖面探明的矿体十分吻合，反演电阻率剖面400 m处切面和时间常数τ圈定的航电异常与主矿区位置一致。证明航空瞬变电磁法在寻找火山岩型块状硫化物矿床中效果显著，值得在该类多金属找矿工作中推广应用。

To promote the application of airborne TEM in search for polymetallic deposits in covered areas, the authors chose known VMS as the test area. The results show that the low-resistivity anomalies in inversion RDI had the same position as the ground drilling profiles, and that the airborne TEM anomalies delineated by the TAU and the resistivity at the depth of 400 m matched with the known major ore distrct. It is thus held that this method can detect the conductor associated with metals such as VMS and hence this method is worthy of promotion for deep exploration in China.
