///Because of lack of Quaternary volcano activity in China, Quaternary sediments become the main dating material in the study of geological structure, topographic feature and environment evolution, etc. ESR is a potential dating method for the sediments older than 200ka. In this study, the paper firstly makes a simple introduction on the ESR theoretical basis and the measuring process of dose rate (D) and equivalent dose (ED), and then, reviews the sunlight bleaching characteristics and the applications in Quaternary geochronology of different ESR signal centers. The E’-center ESR signal increases with the sunlight bleaching during first 72 hours, it is not suitable for the sediment dating. According to the review of all the ESR signal centers’ sunlight bleaching characteristics and several successful application examples, we suggest that Ti-center ESR signal is more suitable than others for the ESR dating of Quaternary sediment.
