CLIMATIC STRATIGRAPHIC RE-DIVISION AND CORRELATION OF CAVE SEDIMENTS AT LOCALITY 1 IN ZHOUKOUDIAN, BEIJING

LIU Ze-chun, ZHOU Chun-lin, and CHEN Ye (Geo-science College, Nanjing Normal University, Nanjing, 210097)  
The cave sediments at Locality 1 in Zhoukoudian, Beijing, more than 40m thick, have been divided into 17 layers. According recent dating by TIMS, the age of the sediments has been prolonged by about 200 ka. On the basis of cluster and factor analyses of the mammal fossils and sporopollen preserved in the cave sediments and of the vicarious paleoclimatic indexes such as the weathering index and the content of trace elements, the paleolclimatic cycles recorded in the cave sediments were quantitatively re-establised. Based on the age of Layer 2(410ka B.P.by TIMS) and the paleomagnetic B/M boundary measured in the upper part of Layer 14, Layers 1—14 of the cave sediments may be re-correlated with Stages 11—19 of the δ 18O curve of deep-sea cores of the S 4—S 7 series of the well-established loess-paleosol sequence in China. Furthermore, it is even possible to compare secondary climatic variations in each major paleoclimatic cycle.
