The project for compilation of Regional Geology of China has been implemented for eight years, and the work has been carried out at the provincial and regional level, covering twenty-four provinces and two autonomous regions. During this period, the compilation work for eleven provinces was completed and has passed the check acceptance, and the results are to be published soon. The compilation is a huge comprehensive and integrated work for these regions or even for whole China. Some innovative achievements have been gained: Precambrian geology research has got major breakthrough; some regional and national stratigraphic systems have been reclassified; the spatial-temporal distribution of magmatic rocks has been analyzed and summarized; the tectonic units have been divided and, as a result, the understanding of the geological structure of China has been deepened; the typical oceanic-basin stratigraphic systems have been detected; the three-dimensional geological map has been successfully compiled. The completion of the project for compilation of Regional Geology of China will provide a series of basic geological monographs which are expected to exert tremendous influence on China's geological work as well as on national economy and social development.
