摘要
回顾并评述了近十年来国内外奥陶纪年代地层学研究的进展和存在问题 ,特别论述了奥陶系的系、统、阶 3级全球界线层型剖面点 (GSSP)的研究和选定工作 ,探讨我国地层学家在奥陶系内部在我国再获“金钉子剖面”的可能性和可行性 ,并提出我国奥陶系的统和阶与国际接轨的原则和方法。
The present paper gives a commentary on progresses and problems of the Ordovician chronostratigraphy in global scale. In particular it deals with the study and selection of the Ordovician Global Stratotype Section and Point (GSSP) in System, Series and Stage ranks. The authors define the possibility of another GSSP within Ordovician System based on some candidate sections in China. Finally, principal and method of correlation of Ordovician Series and Stages between China and global standard have also been defined.
