Abstract
More numerical dating data of Quaternary glaciations in wide areas of Tibetan plateau are necessary to understand the paleoglacial climatic dynamic in the plateau. We have dated and collected 67 data of radiocarbon dating and found five Quaternary glacier advances at 40~56ka, 24~16ka, 11.5~10.4ka, 3.1ka, 2.8~2.5ka and Little Ice Age. Few data suggest MIS3b was present in southwestern Tibet, indicating that there might be a strong wet current flowing from India ocean to southwestern Tibet.
