Breccias are distinct and prominent features in the fluid-saturated environment. Ichinokawa is situated in Central Shikoku which preserve an excellent record of hydraulic induced brecciation consist of 2 breccia types based on PSD. Fractal analysis indicates that there is a positive correlation between pipe size and clast diameter. Fractal dimension also indicates the changing of brecciation energy, From high energy dilatational breccia (type 1) to lower energy of attrition breccia (type 2).
