摘要
通过对贵州七星洞 ZFQX1石笋进行 TIMS——铀系定年及其生长率分析 ,获得了距今 43.0 2 - 1 2 .65 ka的古气候信息。该石笋反映了此阶段贵州地区经历了暖湿——冷干——暖湿的气候演变趋势 ,这与全球古气候变化波动基本一致 。
On the basis of the studies of TIMS-U series dating and the growth rate in the ZFQX1 stalagmite from Qixing Cave in Guizhou Province, the paleoclimatic information has been obtained from 43.02Ka B.P to 12.65Ka B.P. The results show the records of climatic changes in this period in the Guilin area with a change cycle formed the shift of humid from warm to cold dry and then warm again. It coincides with the fluctuation of global paleoclimate, characteristic of the regional climatic change.
