Heinrich event 4 and Dansgaard/Oeschger events 5-10 recorded by high-resolution speleothem oxygen isotope data from central China
A 50-yr resolution reconstruction of climate and environment variability during the period 43-14ka was developed using 26 high-precision U/Th dates and 390 oxygen isotope (δ18O) data of a stalagmite (SJ1) collected from Songjia Cave in central China, which is close to the northwestern boundary of th...

A 50-yr resolution reconstruction of climate and environment variability during the period 43-14ka was developed using 26 high-precision U/Th dates and 390 oxygen isotope (δ18O) data of a stalagmite (SJ1) collected from Songjia Cave in central China, which is close to the northwestern boundary of the Asian summer monsoon (ASM). The δ18O record in SJ1 displays significant millennial-scale changes that correlate well in timing and duration with Dansgaard/Oeschger (D/O) events 5-10 and Heinrich event 4 (H4) identified in high-latitude regions of the Northern Hemisphere. Four 230Th dates constrain the H4 event precisely to the period of 39.7 to 38.3ka. Notable centennial variations of the ASM activity could be observed within the H4 event.
