SUMMARY We measured the P-wave velocities (VP) of mafic high-grade metamorphic rocks at 1.0 GPa pressure and a range of temperatures from 25 to 400 °C, along orthogonal directions corresponding to macroscopic fabric elements in the specimen. Our res

SUMMARYMagnetotelluric (MT) observations have revealed subvertical electrical conductors that extend from shallow depths into the mid-crust at various geothermal zones, active volcanoes and active faults worldwide. These deeply rooted subvertical con

It has been suggested that a large amount of crustal fluid is trapped at a supercritical state within intrusive rocks beneath volcanoes or calderas near the mountain ranges of northeastern Japan. If we could extract and use these crustal fluids, we c

In this study, we attempt to clarify the heterogeneous CO2 distribution in homogeneous and high-permeability porous sandstone (Mt. Simon sandstone: 105 mD) using both physical rock experiments and fluid mechanical analyses. In particular, the experim

Evaluating and monitoring the CO 2 behavior in the reservoir, understanding the mechanism of CO 2 flow and distribution in the water-CO 2 mixture state is essential. In this study, measurement of the complex electrical impedance ( Z ) and P-wave velo
