| 摘 要： | 为了说明天然场激发极化法的应用效果,选取了一多金属矿区为试验区。在该区同时进行了常规的中梯激发极化法和大地电磁测深法测量。资料分析对比研究表明,大地电磁的相对视频散率异常和中梯激发极化异常在异常的范围和幅度上都吻合得很好。研究结果说明,天然场激发极化法在一定条件下进行多金属矿勘探是有效的。

| Abstract: | To validate the effect of Natural Field Induced Polarization (NFIP), a certain polymetallic deposit was chosen as the test site, where Induced Polarization (IP) using gradient array and the Magnetotelluric (MT) sounding were conducted simultaneously. Analysis and comparison of the data indicated that the anomaly of the Relative Percent Frequency Effect (RPFE) from the MT data and the anomaly of IP coincided well with each other in the extents of the anomalous site and anomaly magnitudes. The results showed that NFIP was effective in the exploration of polymetallic deposits, under certain conditions. |
