EH-4大地电磁测深法在某铜矿普查中的应用

摘要

Nowadays the use of EH-4 instrument magnetotelluric sounding survey, because lightweight, efficient, large range of exploration, not high resistivity layer shielding for high-conductivity layer strong resolution; stronger lateral resolution capability, and access to a wide range of measurement application. In the census on a copper project, through the analysis of bathymetric data, to be more accurate distinction between bedrock and the target layer. Again with the precision magnetic survey confirms the exception, and then focus on the delineation of the next work area.%现今使用EH-4仪器进行大地电磁测深法勘，因其轻便、高效、勘探范围大、不受高阻层屏蔽对高导层分辨能力强；横向分辨能力较强，而测获得了广泛的应用。在对某铜矿普查项目中，通过对测深资料的分析，能够较为准确的区分基岩和目标层。再通过与高精度磁测异常的印证，进而圈定下一步重点工作区。
