摘要
Stalagmite WX42A was collected roughly 1 000 m deep from the Wanxiang Cave entrance in 2003. Wanxiang Cave is located on the northwest margin of Asian summer monsoon area, where the climate responses are very sensitive to the changes of the summer monsoon. Based on the gray scale data and the 230 Th dating results, the gray scale time series of the stalagmite WX42A grown during the last deglaciation was established. From 17.6 ka B.P. to 12.8 kaB.P. , the gray scale varied between 125 and 195, with an average of 156.of
