摘　　要：简要介绍"国际地层表"(2008)对"国际地层表"(2004)作出的一些修改:恢复了第四系,完善了下古生界与前寒武系的年代地层单位系统,增加了14枚金钉子,更新了一些同位素年龄数据。为了使读者了解更多磁性地层学与全球海平面变化的情况,在刊出"国际地层表(International Stratigraphic Chart)"(2008)的同时还附上了"地质年代表(Geologic Time Scale)"(2008)。As a successor to the ＂International Stratigraphic Chart＂ （2004）, the ＂International Stratigraphic Chart＂ （2008） was constructed by the International Commission on Stratigraphy （ICS） in 2008 . Some updates in the new chart may be outlined as follows： the Quaternary was readopted as a formal Period/ System of the Cenozoic; chronostratigraphic frameworks of the Lower Palaeozoic and Precambrian were greatly refined; 14 new GSSPs were formalized, and some radiometric ages were revised. To aid correlations using magnetostratigraphy and eustatic oscillations, the ＂International Stratigraphic Chart＂（2008） is present together with the ＂Geologic Time Scale＂（2008） .
