This database covers the spatial scope: ① Central Asia (Kazakhstan, Kyrgyzstan, Tajikistan, Uzbekistan). The main data contents include: ① 1:1.5 million scale geological dataset (geological bodies and structures); ② Metallic mineral resource dataset (ore deposits, mineral occurrences, mineralization spots). The main maps include the 1:1.5 million scale geological and mineral resources map of the four Central Asian countries. The spatial database is developed on the ArcGIS platform, which can provide fundamental data support for regional metallogenic regularity research, resource potential assessment, strategic prospective area delineation, and compilation of various thematic maps. The database is stored as a File Geodatabase (.GDB), and the accompanying files include ArcGIS Map Documents (MXD) and raster maps (JPG). Various common graphic formats such as PDF, TIF, and EPS can also be generated as needed. The 1:1.5 million scale geological and mineral data of the four Central Asian countries adopts the Lambert Conformal Conic Projection, with the central meridian at 67°E and two standard parallels at 30°N and 50°N.

Data sources and processing methods: Basic geological data mainly comes from Academician Ren Jishun's compiled *Asian Geological Map (2015)* (1:5,000,000 scale), Central Eurasian Tectonic and Metallogenic Map and Geological Map (2008) (1:2,500,000 scale), and geological maps (1:1,000,000 scale) from national geological survey agencies within the region. ② Mineral data mainly comes from the results of the National Mineral Resource Potential Assessment Project (2012), the Central Asian mineral database and thematic maps from the Natural History Museum, London, UK (2014), the US Geological Survey Afghanistan Dataset (2008), relevant data from national geological survey agencies in the region, and related academic papers and monographs on minerals in the region. In addition, a large amount of remote sensing data was used to modify and improve various data, including ETM+, OLI, ASTER, Worldview imagery, and 90m, 30m, and 12.5m DEM data.

Data quality description: To meet the needs of pan-third pole regional metallogenic regularity research, geological and mineral resource map and metallogenic prediction map compilation, the data was edited, processed, and supplemented in terms of spatial accuracy, logical consistency, and data integrity. The specific work includes: ① Vectorization: A large number of vectorization tasks were carried out based on the aforementioned data to supplement the missing digital data in regions such as Iran and Pakistan. Meanwhile, polygon and line features were merged or split according to the update degree of the data. The vectorization work was completed in accordance with the scale accuracy requirements of relevant Chinese specifications. ② Topological processing: Eliminate topological errors such as overlapping polygons and void areas. ③ Improve feature attribute structure and supplement attribute content: A corresponding data model was established based on relevant Chinese specifications, combined with specific data and content, targeting the goals of regional metallogenic regularity research, geological and mineral resource map compilation, and metallogenic prediction map compilation. The attribute structures of geological body, structure, and mineral feature classes were improved, and the corresponding attribute information was filled in. ④ Based on the above data processing results, combined with the pan-third pole research results and latest understandings, relevant geological contents in the region were further revised and improved.

Data application results and prospects: The geological and mineral resource dataset of the four Central Asian countries mainly serves the regional metallogenic regularity research, geological and mineral resource map compilation, and metallogenic prediction map compilation in Central Asia within the pan-third pole region, with a scale of 1:1.5 million (for the four Central Asian countries).
