| Abstract: | Recently it has been discovered that many lakes on the north margin of Qinhai-Xizang Plateau had expanded during Last Glaciation Maximum, around 18 000 a B.P., and the lake level was 10-40 m higher than that at present. The lake transgression started and evded earlier in the west part than that in the east part of the plateau. The reasons of lake transgression during Last Glaciation Maximum are related to the increase of ice and snow melt-water in warm season and to the reduction of lake evaporation. The discovery of lake transgressional stratigraphy has important theoretioal significance for recorgnizing and evaluating the role of Qinhai-Xizang Plateau in Global environmental changes. |
