Heinrich event 4 and Dansgaard/Oeschger events 5–10 recorded by high-resolution speleothem oxygen isotope data from central China
Abstract A 50-yr resolution reconstruction of climate and environment variability during the period 43–14 ka was developed using 26 high-precision U/Th dates and 390 oxygen isotope (δ 18 O) data of a stalagmite (SJ1) collected from Songjia Cave in central China, which is close to the northwestern bo...
