1. In the previous studies, it has been suggested by the revaluation of casestudies for known mineral resources and geology area that the high-resolution analysis of the earth structure could be achieved by a surface-to-hole and a cross-hole resistivity surveys. A software to simulate the resistivity structure by so-called 2D-3D finite element method was invented, and the validity of this software was confirmed for several geologic models.2. Modeling of a surface-to-hole and a cross-hole resistivity methods were discussed, and it was clarified numerically that surface-to-hole apparent resistivity contour maps and cross-hole apparent resistivity sections gave three-dimensional informations about the target.3. A consideration about the effects of geologic noise, for example, a vertical fault was discussed. As the results, a vertical conductive target body should be detectable using the surface-to-hole and cross-hole methods although the fault itself produces apparent resistivity anomalies.

1.在以前的研究中，通过对已知矿产资源和地质区域的案例研究的重新评估，建议通过地面到孔和跨孔电阻率测量来实现地球结构的高分辨率分析。开发了二维-三维有限单元法模拟电阻率结构的软件，并通过几种地质模型验证了该软件的有效性.讨论了井间视电阻率法和井间视电阻率法的建模问题，并通过数值计算阐明了井间视电阻率等值线图和井间视电阻率剖面提供了目标体的三维信息.以垂直断层为例，讨论了地质噪声的影响。因此，尽管断层本身产生视电阻率异常，但垂直导电目标体应可使用地面到井和井间方法检测。
