文章详细介绍了最近INUQA组织和INQUA地层与年代学委员会在“Episodes”杂志 2 0 0 4年第 2 7卷第 2期公布的新的地质时代标尺 ,并就关于“第四系”这个地层单位的重新定义问题提出了重要的见解。对于取消“第四纪”(Quaternary)一词 ,发表了意见以及不认同的观点 ,同时文章还呼吁 ,希望更多的从事第四纪研究的工作者踊跃发表意见、积极呼吁 ,使“第四纪”(Quaternary)一词正式保持不变。

A discussion was made on the new revised geologic time scale (F.M.Gradstein et al .) and the proposal to redefine the Quaternary (B. Pillans) both appeared in Episodes, Vol. 27, No.2, June 2004. The author reject the proposal that the Quaternary be redefined as a Subsystem (Subperiod) and support the present opinion to retain the Quaternary as a formal chronostratigraphic unit; that is a System(Period)in the new geologic time scale of 2004.
