应用可控源音频电磁和时域激电单极—偶极测深法勘查金矿

APPLICATION OF CSAMT AND TDIP UNSYMMETRIC SOUNDING IN EXPLORATION GOLD DEPOSIT

概述了测区地质、岩(矿)石电性特征。根据金矿床成矿过程中有各类蚀变体—硅化体、黄铁矿化和多金属硫化物伴生,针对测区存在覆盖层厚和高压线密集的客观环境,勘查金矿时选择CSAMT和TDIP单极-偶极测深进行构造及硫化物空间位置的圈定,在勘探区应用地球物理方法取得了较好地质效果。

This paper summarizes the geological character and the electricity character of rock （ore） in the surveying area. According to gold deposit minerogenetic process, there are many kinds of altered mineral -associated silicolites, pyrites and multiple metal sulfides . It is the objective circumstances that the surveying area is aimed at heavy cover and dense high power lines. So we choose CSAMT and TDIP unsymmetric sounding to decide on the space location of structure and silicolites when surveying gold deposit. In the end, it also gives the geological effect in applying the geophysical method to the exploration gold deposit.
