| Outline of Final Research Achievements |
The present study aimed at establishment of the experimental procedures of quantitative assessment of anisotropy of permeability of rocks. To achieve the mission, ferrofluid experiments based on low- / high-pressure treatments were executed on a turbidite sequence burying a foreland basin, of which sedimentological and tectonic backgrounds had been elucidated. For all of the processed samples, tomographic images were obtained utilizing a micro-focus X-ray CT scanner that succeeded in visualization of the three-dimensional pore and fracture networks in rocks. Geologic ages of the analyzed rocks were determined by means of fission-track and U-Pb dating methods. Thus we clarified spatiotemporal distribution of various tectonic events and successfully evaluated their impact on microscopic rock fabrics envisioned through the ferrofluid impregnation experiments.
