This database has the following spatial coverage: ① Central Asia, including Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan. The dataset content is as follows: ① Central Asia metallogenic geological setting and dominant mineral species dataset; the main map includes the Metallogenic Geological Setting and Dominant Mineral Species Distribution Map of Central Asia (1:2,500,000). The spatial database is developed on the ArcGIS platform, which can provide basic data support for regional metallogenic regularity research, resource potential assessment, strategic prospective area delineation, and compilation of various thematic maps. The database is available in File Geodatabase (.GDB) format, and the accompanying map files include engineering files (.MXD) and raster maps (.JPG). It can also generate various common graphic formats such as PDF, TIF, and EPS upon request. The Central Asia metallogenic belt-prospective area-mineral concentration zone-mineral data adopts the Lambert Conformal Conic Projection, with the central meridian and standard parallels determined based on the specific location.

Data sources and processing methods: Basic geological data mainly come from the Asian Geological Map (1:5,000,000, 2015) compiled by Academician Ren Jishun, the Central Euro-Asian Tectonic Metallogenic Map and Geological Map (1:2,500,000, 2008), and geological maps (1:1,000,000) from the geological survey departments of countries in the region; ② Mineral data mainly originate from the achievements of the National Mineral Resource Potential Assessment Project (2012), the Central Asia Mineral Database and Thematic Maps of the Natural History Museum in London, UK (2014), the Afghanistan Dataset of the U.S. Geological Survey (2008), relevant data from the geological survey departments of countries in the region, and academic papers and monographs related to regional minerals. In addition, a large number of remote sensing data have been utilized for data modification and improvement, including ETM+, OLI, ASTER, and Worldview image data, as well as 90m, 30m, and 12.5m DEM data.

Data quality description: To meet the requirements of Pan-Third Pole regional metallogenic regularity research, geological and mineral map compilation, and metallogenic prediction map preparation, edits, processing, and supplementary improvements have been conducted in terms of spatial accuracy, logical consistency, and data integrity. The specific work includes: ① Vectorization: A large number of vectorization tasks have been carried out based on the aforementioned data to supplement areas lacking digital data (Iran, Pakistan). Meanwhile, various surface and line features are merged and split according to the update status of the data. The vectorization work is completed in line with the scale accuracy requirements specified in relevant Chinese standards; ② Topology processing: Eliminate topological errors such as overlapping surfaces and empty areas; ③ Improvement of feature attribute structure and supplementation of feature attribute content: Centered on the goals of regional metallogenic regularity research, geological and mineral map compilation, and metallogenic prediction map preparation, and in accordance with relevant Chinese specifications, combined with specific data and materials, a corresponding data model is established, the attribute structures of geological body, structure, and mineral feature classes are optimized, and the corresponding attribute filling work is completed; ④ Based on the above data processing contents, combined with the research results and latest understandings of the Pan-Third Pole region, relevant geological contents within the region have been further modified and improved.

Data application achievements and prospects: The Central Asia metallogenic geological setting and dominant mineral species database mainly serves the metallogenic regularity research of the Pan-Third Pole's Central Asia region, important metallogenic belts, and national-level regions, as well as the compilation of the Metallogenic Geological Setting and Dominant Mineral Species Distribution Map of Central Asia at a scale of 1:2,500,000.
