Many quartz veins that filled mode I cracks (extension quartz veins) can be observed in the hanging wall and footwall of the Nobeoka Thrust. In this study, the equilibrium and kinetic model of the formation of the extension quartz veins along the Nobeoka Thrust were estimated to consider the relationship among the distribution of quartz veins, the time scale of crack sealing and the cycle of seismic activities.
