Abstract:

基于黔北三星洞石笋(SX29)9个铀钍年龄和420个氧同位素分析,获得了113.6±0.3~106.2±0.4kaBP(相对于1950年)10年际分辨率的δ18O时间序列.该石笋δ18O时间序列记录了MIS5d/5c转换时亚洲夏季风强度变化的突变过程.根据突变过程中间点的年龄确定MIS5d/5c突变时间为108.1±0.3kaBP.石笋记录对MIS5d/5c突变时间的精确标定可以作为MIS5阶段重要的年龄控制点,用以校正南北极冰芯记录和深海沉积记录的时间标尺.季风MIS5d/5c转换阶段也表现为类似过去4个冰消期的2个阶段变化过程阶段Ⅰ为夏季风较弱时期,而南极温度缓慢上升;阶段Ⅱ为夏季风快速增强时期,与甲烷浓度突变同步,南极温度则上升至最高值.
