| Outline of Final Research Achievements |
It has been reported that when an igneous rock is subjected to nonuniform loading, electric current flows from the loaded volume toward unloaded volume and the surface charges positive. This would be because of positive hole carriers that are activated in the loaded volume. Here in this study, using vaccume-dried gabbro blocks, the thermo-electromotive force of the loaded/unloaded volume was measured, and the Seebeck coefficient was calculated. From its positive value and its change due to loading, it is found that positive hole carriers are activated in the loaded volume. On the other hand, based on the 3D finite-element analysis of the load gabbro blocks, relationships (e.g., between the strain and carrier number) are roughly estimated.
