瞬变电磁法在雷门沟钼矿勘查中的应用效果分析

雷门沟钼矿属于角砾岩型钼矿床,就其赋存状态来说,从里到外为角砾岩钼矿体-角砾岩-正常围岩,矿体边界不清,矿体地表没有出露。角砾岩和围岩视电阻率差异明显,物探方法在该区具有物性前提。瞬变电磁法在该区的应用,取得了较好效果,建立了地质地球物理模型,为合理布置勘探工程寻找钼矿提供了依据。本文在简要介绍瞬变电磁法原理的基础上,以雷门沟钼矿勘查为例,重点对该方法技术的数据处理、资料解释、应用效果及一些技术问题进行了分析论述。

TEM in Leimengou Molybdenum Ore Exploration Application Effect Analysis

Leimengou molybdenum ore belongs to the breccia type molybdenum deposit,its occurrence,from inside to outside for breccia molybdenum ore-breccia-normal rock,ore body boundary is not clear,the surface is not exposed.Breccia and rock resistivity difference is apparent,geophysical prospecting method in the region has a physical property.Transient electromagnetic method in the area of application,obtained better result,established the geological geophysical model for rational arrangement of exploration engineering,provides the basis for molybdenum.This paper introduces the transient electromagnetic method based on the principle of thunder,molybdenum ore exploration as an example,the focus of the technique data processing,data interpretation,application effect and some technical problems in some analysis author.
