中国东阁洞石笋的钍230年龄和氧同位素比值表征了过去16万年的亚洲季风和低纬度降水。 18O/16O 值的许多突变是由日照和千年尺度环流变化驱动的热带和亚热带降水变化造成的。最后一次间冰期季风持续了9.7±1100年，开始于129.3±0900年前18O/16O值突然（不到200年）下降，以119.6±060年前18O/16O值突然（不到300年）上升结束。开始与日照上升和完全间冰期条件的测量同时发生，表明日照触发了完全间冰期条件的最终上升。
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.
