Under shallow and low temperature situation, it is very difficult to form new metamorphic minerals in movement of brittle faults. Therefore we cannot determine the active ages of faults exactly through traditional method. But in activation of shallow faults, there is often homochronous quartz veins formed. By obtaining the ages of quartz veins by thermal activated ESR dating, the active ages of faults can be well supplied. If there were several stages of quartz veins in fault belts, the corresponding active ages of them can also be determined. In this paper, ESR dating method was used to get the active ages of two fault belts in Xuefeng Mountain, with getting a series of age from 202.3 to 60.6Ma. Then, discuss the movement stages of Anhua-Xupu and ZhangjiajieHuayuan fault belts since Indosinian. Finally, the creditability and condition of applying ESR dating were discussed.
Key words： Electron spin resonance(ESR); Fault; Xuefeng mountain.
