摘要

The existence of a grate glacial in Tibet of Eopleistocence has been raised by some people, but this theory hasn’t been paid attention for no discover of glacial deposit. Through the 1∶250 000 regional geological survey in the project of “Kangxiwa” “Qiaha” “Chalukou” “Akesayi Lake”, first time, the authors found Eopleistocence drift deposit in the area of Tianwentai-Qiaortiantan in 2003. The distribution feature of the drift deposit has no relationship with present land form, which indicates Earth crust occurred with differential uplift movement after the formation of this glacial deposit. The discovery of the drift deposit furnish direct evidence to the existence of Eopleistocence glaciation in the Tibet plateau, offering reliable information for research of “Grate Ice Sheet” and “Universal Grate Lake” theory of Tibetan Plateau and has important significance to further research of land dynamics and crust tectonic evolution.
