Subannual-to-biannual-resolved travertine record of Asian Summer Monsoon dynamics in the early Holocene at the eastern margin of Tibetan Plateau

In this study, we present a subannual–biannual-resolved (0.9–2 years) ASM intensity record spanning from 11.6 to 10.0 ka BP (before 1950 AD) inferred 230Th-dated travertine δ18O at Zhangjia Ravine on the eastern margin of Tibetan Plateau. The ZJG-1 sequence is characterized by high-frequency fluctuations decadal centennial scales. Fluctuating between −11.15‰ and −14.78‰ over sequence, fluctuation range gradually decreased BP. There are several abrupt changes in which indicate that early Holocene was highly unstable. Comparison with marine records suggests Preboreal oscillation (PBO) event could be triggered freshwater outburst led to/resulted sudden release thousands cubic kilometers meltwater North Atlantic Ocean. Furthermore, climate oscillations during PBO were associated complex interplay solar activity outburst, may amplify effect when it minima. rapid warming after controlled common mechanism induced Dansgaard–Oeschger events last glacial period. further pronounced increases values occurred about 10.3 BP, coinciding roughly Bond 7 event, also caused activity. This study not only important understand primary driving force Holocene, but essential for evaluate probability future.
