Glacial events during the last glacial termination in the Pagele valley, Qiongmu Gangri peak, southern Tibetan Plateau, and their links to oceanic and atmospheric circulation
During the last glacial termination, a warming trend was generally interrupted by rapid millennium-scale cold reversals, such as the Greenland (Isotope) Stadial 1 (GS-1) and GS-2a events. To understand how glaciers on the Tibetan Plateau (TP) responded to these rapid climate events, this study constrained the timing and extent of three glacial events during the late-glacial period. Specifically, using a cosmogenic 10 Be exposure dating method, we…
Extensive glacial advances during the Last Glacial Maximum near the eastern Himalayan syntaxis
Cosmogenic 10 Be surface exposure dating of ‘Little Ice Age’ glacial events in the Mount Jaggang area, central Tibet
The timing and extent of ‘Little Ice Age’ (LIA) glacial advances on the Tibetan Plateau (TP) are critical for understanding climate during the past millennium. However, the lack of LIA chronologies in central Tibet makes it difficult to fully understand the nature of LIA throughout the TP. In this study, two presumed LIA moraines in the east of Mount Jaggang, Xainza range, the central TP, were examined and dated using 10 Be surface exposure datin…
A Case Study Using 10 Be- 26 Al Exposure Dating at the Xi’an AMS Center
Exposure age dating using in situ 10 Be and 26 Al is a very useful technique for dating fluvial terraces. This is especially true in semiarid regions where other methods suffer from a paucity of suitable dating materials. This article describes sample preparation procedures and analytical benchmarks established at the Xi’an Accelerator Mass Spectrometry (AMS) Center for the study of in situ 10 Be and 26 Al. Four intercomparison samples were analy…
Lake-level fluctuations since the Last Glaciation in Selin Co (lake), Central Tibet, investigated using optically stimulated luminescence dating of beach ridges
This paper presents a preliminary study on lake-level fluctuations since the Last Glaciation in Selin Co (lake), Central Tibet, by dating four groups of beach ridges using optically stimulated luminescence (OSL). The highest/oldest beach ridge group (>100 m higher than the current lake level) is dated back to 67.9 ± 2.4 ka BP, corresponding to the early stage of the Last Glaciation (marine isotope stage (MIS) 4). This date further supports that n…
