江西余江马荃地区EH4大地电磁测深资料解释

本文介绍了江西余江马荃地区的工区地质、大地电磁测深的基本原理和技术方法。为查明该区F1构造特点、变质岩基底起伏情况及含矿“槽洼”构造情况，采用EH4连续电导率成像仪（简称为EH4）对该地区进行勘测，通过剖面地电特征分析和反演解释，研究工作区地表以下1000m深度范围内地层分布、岩性特征、基底起伏和构造展布等地质问题，为该区探矿提供地质依据。

The Data Interpretation of EH4 Magnetotelluric Method in Maquan Yujiang of Jiangxi

This paper introduces the geology of work area in Maquan Yujiang Jiangxi and the basic principle and technique of the magnetotelluric method. In order to detect the F1 structural features of the area, the basement relief situation of the metamorphic and the structure situation of the sags, in this study, we adopt EH4 magnetotelluric method to sur- vey our workplace. Through analysis of the electrical characteristics section and the inverse interpretation, we can research the stratigraphic distribution, lithology characteristics, the basement relief, structural distribution and a series of geological problems of our study area from meters to one kilometer, which provides us the geological basis for prospecting in the area.
