The records provided a clue to the history of Asian summer monsoon for the period of 10.5~5.0 kaB.P.. There are a series of abrupt and rapid shifts superimposed on a gradually increasing trend, indicating that the East Asian monsoon was unstable during the early Holocene. A comparison of our records to precisely dated contemporaneous stalagmite records from other caves shows that the Wanjiawan record resembles other Holocene speleothem records from subtropical locations.
