Summary
Abstract: Thorium-230 ages and oxygen isotope ratios of stalagmites from Dongge Cave,
China, characterize the Asian Monsoon and low-latitude precipitation over the
past 160,000 years. Numerous abrupt changes in 18O/16O values result from
changes in tropical and subtropical precipitation driven by insolation and
millennial-scale circulation shifts. The Last Interglacial Monsoon lasted 9.7
± 1.1 thousand years, beginning with an abrupt (less than 200 years) drop in
18O/16O values 129.3 ± 0.9 thousand years ago and ending with an abrupt (less
than 300 years) rise in 18O/16O values 119.6 ± 0.6 thousand years ago. The
start coincides with insolation rise and measures of full interglacial
conditions, indicating that insolation triggered the final rise to full
interglacial conditions.
