ESR has become an important method to fault gouge, flint, volcanic tephra and sediment （aqueous, aeolian or glacial） dating. The accepted dating range of ESR is limited to Quaternary era. For fault clay and sedimentary samples, the difficulty of ESR signals in quartz resetting to zero makes ESR ages often older than other dating techniques. While the “multiple centers” and “the grain size plateau” criterion are two effective ways to determine whether the ESR signals have reset to zero. In order to extend ESR dating range to pre-Quaternary, the enormously enhanced intensity of E’ signal which was transformed from oxygen vacancies by heating is often used. Since the formation and transformation mechanism of oxygen vacancies in quartz is not clear, the correlation between the increasing ESR signals after heating and the geological age needs to be validated. The closure temperature of quartz ESR is between 49 ℃～82 ℃, which is lower than apatite（U-Th）/He dating method. The quartz ESR can be used to study the tectonic evolution process in lower temperature range. In recent years, luminescence dating methods（including OSL and TL）develop quickly in thermochronology, which have similar principles with ESR. The ESR applications in low temperature thermochronometry show nice prospects. The corporation of ESR, luminescence and apatite（U-Th）/He dating can help to correct each other and enhance the analysis accuracy of tectonic and topographic evolution problems close to the earth surface.
