利用显微镜下计数年层的方法，建立了南京附近葫芦洞3000年的石笋年表。根据230Th年龄，该年表涵盖了末次冰川盛期(LGM)内的24-21kaBP期间。为了建立末次盛冰期高分辨率东亚季风史，沿石笋剖面生长轴测量了年层厚度和灰度级两个指标。两个指标之间的高相关系数(r=0.55)表明，两者都受一个公因子控制，可能反映了夏季风环流强度及其降水的变化。年层厚度从百年到千年尺度的低频变化与格陵兰冰芯记录的10Be通量基本一致，表明东亚季风强度的变化可能是由末次盛冰期的太阳输出所强迫的。为支持这一点，对年层厚度的傅里叶功率谱分析显示，某些十年至百年尺度的周期与太阳活动的周期很好地吻合。
A 3000-year-long stalagmite chronology from Hulu Cave near Nanjing was established by counting annual layers under microscope. Based on the230Th age, this chronology covers the period 24-21 kaBP, within the Last Glacial Maximum (LGM). Two proxies, annual layer thickness and gray level were measured along the growth axis of the stalagmite profile in order to establish a high-resolution East Asian monsoon history during the LGM. The high correlation coefficient (r= 0.55) between the two proxies suggests that both of them were controlled by a common factor, possibly reflecting changes in the strength of summer monsoon circulation and its precipitation. Low frequency variations of the annual layer thickness, ranging from centennial to millennial scales, are approximately in agreement with the10Be-flux recorded in the Greenland ice core, indicating that changes in East Asian monsoon strength might be forced by solar outputs during the LGM periods. In support of this, Fourier power spectrum analysis of the annual layer thickness showed certain decadal to centennial-scale cycles that agree well with the periodicities of solar activity.
