Outline of Final Research Achievements

Usage of underground and surrounding environment has been development particularly for LPG storage, CO2 storage and radioactive waste disposal. Based on the background, water conducting fractures are focused on to understand the characteristics. The results are to reveal the formation process of fracture and sealing by fillings in the crystalline rocks distributed in orogenic field of Japan.
