Abstract：The Quaternary was an important period in the geological evolution history because it is closely related to the human beings. Therefore, highly reliable and precise Quaternary dating is required. Quaternary sediments change overtime in lithology and composition, and may have obvious changes of space in structure and thickness because of different sedimentary conditions and sediment types and geneses, which make it more difficult to determine the accurate ages of Quaternary sediments. This paper presents the new progress in Quaternary dating, such as K/Ar and 40Ar/39Ar dating, tektite dating, uranium dating, Amino acid racemization dating, cosmogenic nuclide dating, and electron spin resonance dating, as well as the dating range and objects of the related methods. Furthermore, the present problems and strategies for improvement of Quaternary sediment dating methods are introduced. However, to improve the reliability and accuracy of dating, not only geological experience, but also correct dating methods are required for comparative dating. With more attention paid to recreation of the Quaternary environment and its relationship with global climate changes, the dating methods for Quaternary sediments should be helpful in investigations of global climatic changes and environment evolution in the future.
