| 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、地质结构和构连；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。

| Abstract: | 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 Platfo... |
