英文摘要
Electrical conductivity measurements carried out at mid-to lower crustal temperature and pressure on various rocks and minerals showed a stable and reversible trend. To obtain such stabilized conductivity data, repeated heating and cooling before measurements were required, and the samples should be maintained for long duration at maximum temperature. In our study, we carefully considered measurement orientation for rock samples. Conductivity measurements perpendicular and parallel to mineral foliation in some rocks indicated an order difference in conductivity at the same temperature range. We also obtained unique values of activation energy for various samples. These values were examined and compared with those of other rock type groups obtained by former studies. To evaluate conduction mechanism, mineral compositions and petrofablic of recovered samples, we conducted EPMA analysis after electrical conductivity measurements. This analysis proves that there is no major change in the chemical or physical aspects of the samples before and after measurement. Consequently, experimental results can be compared with those of former EM soundings. Remarkably, conductivity of the mid-to lower crust inferred from field measurements corresponds to that of rock samples.
