摘要
地磁测量能直接反应地下地质体的磁性特征,在国内外被广泛应用于直接寻找磁铁矿,而作为寻找隐伏构造的应用较少,为了查明地磁测量在沙漠(戈壁)覆盖区寻找隐伏构造的地球物理方法有效性及隐伏构造的磁性特征。本文以内蒙某矿区地面高精度磁测为例,运用化极、延拓、方向导数处理,结合地质资料综合分析。推测断层4条,得出沙漠(戈壁)覆盖区隐伏构造的磁性特征,以此进行推广应用。
Geomagnetic measurement can directly reflect the magnetic characteristics of underground geological bodies and is widely used in the direct search for magnetite at home and abroad,but it is less used to find hidden structures.In order to find out the effectiveness of geophysical methods and magnetic characteristics of hidden structures in desert(Gobi)covered area.This paper takes the ground high precision magnetic survey of a mining area in Inner Mongolia as an example,using the treatment of pole,extension and directional derivative,combined with the comprehensive analysis of geological data.The magnetic features of the hidden structures in the desert(Gobi)cover area are obtained by inferring 4 faults,so as to be popularized and applied。
