摘要
利用大地电磁测深法(MT)反映地质体的电性差异,首先可以确定地质体的空间展布、地质结构和构造;而由于地质体电阻率受地热水影响而降低,进而据此圈定地热水的分布范围;并在此基础上可以进一步探讨地热形成机制。在华北地台地热勘探中MT法取得了较好的勘探效果。
Based on differences in electrical properties of geologic bodies disclosed by telluric electro-magnetic sounding method （MT）, we can get to know spatial distribution, geological structures of the bodies at first. The resistivity of a geologic body will decline as a result of the effect of geothermal water, so the range of influence of geothermal water can be determined. On such a basis, we probed into the forming mechanism of geothermal resources during exploration of geothermal resources in the North China Platform and a good result was obtained.
