Variation of the Asian summer monsoon since the last glacial-interglacial recorded in a stalagmite from southwest China

A high-precise 230Th dated stalagmite from southwestern China was used to reconstruct the changes of ASM and regional hydrological conditions since the last interglacial (3.6–118.1 ka BP) by the coupled δ18O and δ13C.本研究利用采自中国西南地区的一根经高精度钍-230（230Th）定年的石笋，通过耦合氧同位素δ18O与碳同位素δ13C序列，重建了末次间冰期（距今3.6~118.1 ka BP）以来亚洲夏季风（Asian Summer Monsoon）及区域水文条件的演化特征。
