龙川江盆地电阻率特征初步研究与应用

Preliminary study and application of resistivity features in Longchuanjianb basin

本文介绍了应用EH4电阻率成像系统研究龙川江盆地基底以及玄武岩盖层特征的成果 ,根据对实测资料的解释 ,划分出盆地不同部位基底、玄武岩、沉积岩系的分布。在圈定电性差异明显的地质体时 ,该物探方法十分有效。

This paper introduces the research achievemen ts of the basement and basalt cover of Longchuanjiang basin obtained by applying t he EH-4 resistivity images system. According to the interpretation of the surve y data, the distribution of the basement, the basalt and sedimentary rock series is delineated at different parts of the basin. Research achievements show that the resistivity method is effective in delineating geologic bodies with distinct electric properties.
