Speleothem‐derived Asian summer monsoon variations in Central China, 54–46 ka
The oxygen isotope signature (δ18O) of stalagmite SI3 collected from Shizi Cave in north‐east Sichuan Province provides an Asian Summer Monsoon (ASM) record in Central China for the period 54–46 ka. The SI3 δ18O record clearly shows a negative δ18O excursion centred around 49.4 ka, which was reporte...
