| Abstract: | 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. |
