摘要
以扬子地台、华北地台和塔里木地台早古生代层序地层研究成果和典型范例为基础 ,讨论了层序地层与年代地层和岩石地层单位及其界线之间的相互关系。在年代地层方面 ,进一步强调以初始海泛面 ( FFS)作为优化年代地层“阶”的标准。从自然界线的观点 ,建议将全球界线层型剖面和点 ( GSSP)在层序地层序列中的位置优化至初始海泛面 ( FFS)。探讨了三级层序结构与生物宏演化阶段之间的可能关系。在岩石地层方面 ,强调以层序地层的关键界面 (层序界面、初始海泛面、最大海泛面 )优化组、段界线。
The interrelations of units and their boundaries among sequence stratigraphy, chronostratigraphy and lithostratigraphy are discussed, based on detailed studies and some typical examples of Lower Paleozoic sequence stratigraphy on the Tarim, Yangtze and North China Platforms. It is emphasized that the first flooding surface(FFS) is used as a standard or useful marker in optimizing chronostratigraphic and lithostratigraphic boundaries. It is suggested that the position of the Global Stratotype Section and Point(GSSP) is defined at FFS from the opinions of integrated stratigraphy and nature stratigraphic boundary,although the marks established GSSP are based on biotic evolution and biostratigraphy, so that GSSP have theoretic and practical significance. In this paper the primary relationship between the structure of third-order sequence and biotic macroevolution is discussed. It is presented that the key surfaces(SB, FFS, TS, MFS) of sequence stratigraphy are regarded as an useful marker for improving lithostratigraphic units and their boundaries.
