The database contains information about 232 types of mineral resources in 27 569 deposits in 29 provinces (cities, districts). The scope of this database covers the entire country, thus reflecting the results of mineral exploration in China since the founding of the Ministry of Geology and Mineral Resources. The database was created under stringent quality control measures covering the entire work process and was also revised and corrected through the review process. The database boasts comprehensive data collection, accurate documentation, and accurate data entry. In addition, the data structure and accuracy in this work meets relevant technical standards and its overall quality is reliable. All in all, the database is large and comprehensive featuring ore species, wide coverage, rich content, massive data, and large time span. It provides an important basis for mineral resources survey and evaluation, academic research, mining development, and municipal planning and management.
