Tóm tắt

A 5-year-resolution absolute-dated oxygen isotope record from Dongge Cave, southern China, provides a continuous history of the Asian monsoon over the past 9000 years. Although the record broadly follows summer insolation, it is punctuated by eight weak monsoon events lasting ∼1 to 5 centuries. One correlates with the “8200-year” event, another with the collapse of the Chinese Neolithic culture, and most with North Atlantic ice-rafting events. Cross-correlation of the decadal- to centennial-scale monsoon record with the atmospheric carbon-14 record shows that some, but not all, of the monsoon variability at these frequencies results from changes in solar output.

Eighty-two time-points were selected using a criterion of ≥±10 ‰ fluctuation in atmospheric Δ 14 C for tuning. The tuned DA time scale is within the 230 Th dating error. The tuned age-depth relation remains smooth and is essentially the same as the 230 Th dated age-depth relation (Fig. 1B).
