| Some Problems in Recent Stratigraphic Researches of China |
| There exists abundant important information about the process of earth evolution in the stratigraphy. The system of Global Geologic Time Scale is established based on the stratigraphic research. The establishment of unified Geologic Time Scale can bring about an advance in basic geological research, mineral resources prospecting, geological environment assessment, and geological hazard forecast, prevention and control. Therefore, great importance has been attached to this problem by geologists of various research fields. There are 110 stages in the International Chronostratigraphic Chart. Among them, Global Boundary Stratotype Section and Point (GSSP) of 65 stages are confirmed by the International Commission on Stratigraphy and International Union of Geological Sciences. Ten GSSPs are selected and established in China, making China a country possessing the most GSSPs in the world. There are 102 stages in the Regional Chronostratigraphic Chart of China, in which 59 stages of sections have been given a thorough investigation and study. In addition, some standards of stratigraphic division and correlation of China have been established. Although numerous important achievements have been made in Chinese stratigraphy, there still exist some critical stratigraphic problems which urgently need further thorough investigation, such as establishment and perfection of the regional stratigraphic standards, correlation between regional stratigraphic units of China and the GSSP, establishment of the research methods for stratigraphy of the intensively deformed or intensely metamorphic regions, Mesozoic and Cenozoic continental stratigraphic division and correlation, and protection and standardization of the typical stratigraphic sections of China. |
