| 摘 要： | 本测区地貌极为特殊，位于西部地质条件复杂的锡铁山老矿区，其浅部已知矿开采殆尽，我们的研究任务是在矿山深边部找到隐伏矿。由于测区地形复杂，周边的电磁干扰较为严重，因此我们选用了CSAMT法，它具有勘探深度大，横向分辨率高，抗干扰能力强的特点，可以很好地解决问题。首先，我们根据测区地质条件和岩矿石物性，布置了18条测线开展CSAMT方法的探测研究，接着通过原始数据反演和分析，发现了两个较大的低阻异常区，并推断了两个低阻异常间的关系，最后经推断解释认为：2号低阻异常应为成矿有利区域。

| Abstract: | Because of the complex topographies and strong electromagnetic interference,we choose CSAMT method for the purpose of locating hidden mine body in the deep and outside deposit.This method has the characteristics of deep detection,higher lateral resolution and stronger anti-interfering ability.In this paper,we firstly layout 18 surveying lines according to the geological and mineralizing conditions in mine fields.And then by inversely processing and analyzing the original data,we find out two unusual zones with low-resistance and infer the relationship of the two low resistances.Finally we make a conclusion that the second unusual zone with low-resistance is an ideal zone for mine. |
