| 摘 要： | 国际地层委员会最新表决通过第四系为系级年代地层单位,它位于新近系之上,底界由意大利西西里岛的Monte San Nicola"金钉子"定义,也就是由定义格拉斯阶底界的"金钉子"来定义,年龄值约为2.59Ma;更新统的底界也下移到这个位置,格拉斯阶划归更新统,长期争论的第四系的地位和定义问题有望得到解决。

| Abstract: | The International Commission on Stratigraphy recently voted through proposal for the status and definition of Quaternary,which was submitted by the Subcommission on Quaternary Stratigraphy.The Quaternary should be regarded as a formal unit of System/Period rank,following directly upon the Neogene System/Period,the base of Quaternary is defined by the GSSP at Monte San Nicola,Sicily,Italy,which defines the base of the Gelasian Stage(~2.59Ma).The base of Pleistocene Series/Epoch should be lowered at this posi... |
