It was reported that traces of high and low permeable zones formed by the supercritical fluid flow through granite have been observed in Japan. These traces directly related to current permeability. In this study, we will improve the investigation methods and evaluation technologies considering the influence of supercritical fluids through case studies in the Ningyo-toge area. In this presentation, we will introduce the research plan and the preliminary results.
