摘要
简要介绍CSAMT法的工作原理及河南省渑池县王村地区的地质和地球物理特征,重点论述CSAMT法在王村地区铝土矿勘查中的应用效果。经过WinGlink2D,Occam和Bostick等多种处理方法的比较,CSAMT法在建立剖面视电阻率的基础上,能较准确的定位奥陶系高阻灰岩界面的起伏和埋藏深度,结合铝土矿的成矿规律,能对区内的铝土矿的赋存做出判断。
This paper introduces the working principle of CSAMT briefly, and describes the geological and geophysical characteristics of Wang village of Mianchi county in Henan province. Then it discusses the application of CSAMT in the bauxite mine exploration . Compared with the processing method of WinGlink2D, Occam and Bostick, the application result shows that on the basis of building up resistivity profile, CSAMT can accurately estimate the undulation and depth of the interface of Ordovician limestone with high impedance. Furthermore, with the forming rule of bauxite ore, the region abundant with bauxite mine can be confirmed.
