EH4电磁成像系统在贵州某金矿勘查中的应用

摘要

简要介绍EH4电磁成像系统基本原理以及贵州某金矿区的地质和地球物理特征,重点讨论EH4电磁成像系统在金矿区勘查中的应用效果,通过对电阻率断面图的综合推断解释,划分出含矿层以及地质构造,圈出含矿有利部位.经与已知钻孔资料对比,物探推断与钻孔资料基本吻合,EH4电磁成像系统勘查贵州金矿取得了良好的找矿效果,为贵州金矿勘查提供了例证,具有一定借鉴价值.%The authors briefly introduced the fundamental principle of EH4 electromagnetic imaging system,as well as the geological and geophysical characteristics of Guizhou gold mine area. They discussed the application effect of EH4 elec-tromagnetic imaging system in gold exploration. Through the comprehensive inference and interpretation on resistivity sec-tion diagram,it has divided the ore bearing strata and geological structure,also circled the ore bearing favorable position. Compared to the known drilling data,the geophysical exploration is basically coincided with the drilling data. The EH4 e-lectromagnetic imaging system obtained better prospecting results in gold mine prospection,which provided an example and a certain reference value for the exploration of gold mine in Guizhou.
