| Introduction | I have investigated the deformed/fault rocks exposed in different geological settings (i.e., active faults, crustal shear zones and modern/exhumed accretionary complexes) based on field survey and material analysis, to clarify the structural evolution and physico-chemical processes of crustal faults and subduction thrust faults. Additionally, I have performed laboratory experiments (low- to high-velocity friction experiment, triaxial deformation experiment) in order to quantify mechanical properties of rocks and verify the natural processes in the laboratory. |
