摘要/Abstract

摘要： 根据南京直立人洞穴钙板方解石的TIMS测年 ,南京直立人化石的年代应早于距今50万年。南京猿人洞穴堆积所含哺乳动物化石和孢粉分析 ,表明含人类化石的堆积形成于冷期 ;哺乳动物化石的比较分析和聚类分析认为含南京直立人化石层可对比于北京猿人洞穴堆积的第6层和深海岩芯氧同位素记录的14阶段 ,从而进一步支持南京直立人化石时代早于50万年的TIMS测年结果。

Abstract: Based on the latest U-series dating of flow stone calcite in Nanjing Man Cave ( Little Cave) with TIMS, the age of Nanjing Man may be older than 500 000 years. The analysis of mammalian, spore and pollen fossils indicate that the deposit containing hominid fossils was formed in the cold ( glacial) stage. By the cluster analysis of mammalian fossils in Little Cave and in Peking Man Cave, the layer containing Nanjing Man fossils is correlated with the 6th breccia layer in the Peking M an Cave and the Stages 14 of marine deposits δ18 O. This result approved the new dating by TIMS which suggests that the age of Nanjing Man is earlier than 500 000 years ago with more evidence.
