New progress and problems of Quaternary moraine datingin the Tibetan Plateau

Since the 20^th century, numerous Quaternary moraine dating methods have emerged, including lichenometric, moraine ¹⁴C,quartz sand thermoluminescence (TL), electron spin resonance (ESR), optically stimulated luminescence (OSL) and ¹⁰Be, ²⁶Al,³⁶Cl, ³H, ²¹Ne nuclide dating methods. These dating methods are widely applied to determine moraine ages and have provideda large dataset. Unfortunately each method has its defects. In this paper, we will review these various dating methods and providesome comments.
