英文摘要 | Lake-level changes are important environmental events. The paleoshorelines of a lake reflect past water levels and record information on paleoclimatic changes. Dating these events places the climatic changes in a time sequence. From shorelines similar to 1, similar to 4, and similar to 6 m above current lake level on the eastern shore of Linggo Co, central Tibet, we collected eight samples for optically stimulated Luminescence dating. Two stratigraphic units, distinguished on the basis of color and sedimentology, were recognized beneath each shoreline. The ages obtained were 0.9 ka (upper layer) and 3.1 ka (lower layer) for lowest shoreline, 1.9 ka (upper layer), and 6.1-9.0 ka (bottom layer) for middle shoreline, and 9.6 ka for high shoreline. Two dates were considered to be unreliable due to incomplete bleaching. We attribute the higher lake levels to increased precipitation brought by the Indian monsoon in the Holocene.
