To clarify the faulting process underwent in the brittle-plastic transition zone, we have characterized the deformation microstructure of mylonitic rocks exposed in the North Almora Thrust Zone, which belongs to the Main Central Thrust System. From this study, we were able to clarify the temperature, flow stress and shear sense conditions for mylonitization. The fact that the fluid has a strong influence on precursory rock deformation of faulting is also understood.
