We have used in situ produced cosmogenic nuclides (super 10) Be and (super 26) Al to date lacustrine shorelines around eight lakes in Tibet. Two lakes located south of the Yarlung Tsangpo River discharged at high lake levels. One of them, Drolung Co (Co is a local term, meaning lake), became closed (its water level fell below its outlet channel) at approximately 3.8 ka and lowered over 120 m vertically since then. This implies a significant change in intensity of precipitation driven by the Indian monsoon over southern Tibet in the middle-late Holocene. Nam Co and Dajia Co, located to the north of the Yarlung Tsangpo River, also drained at high lake levels and became closed approximately 53-36 ka and approximately 48 ka, respectively. Of four other lakes developed closely in the Qiangtang basin, north of the Yarlung Tsangpo River, Tangra Yum Co and Siling Co (located at 31-32 degrees N) show exposure ages for high lake shorelines of over 220 ka, the oldest lake shorelines reported for Tibet, while towards the north and west, the high lake of Zhari Nam Co appeared after the Last Glacial Maximum (LGM). The different pattern of lake development to the north of Yarlung Tsangpo River may reflect regional climate effects.
