This database covers the spatial scope of four Central Asian countries: Kazakhstan, Kyrgyzstan, Tajikistan, and Uzbekistan. The core data content includes the Xinjiang-Central Asian metallogenic geological background dataset (covering rock assemblages, tectonic divisions, metallogenic belts, prospective areas, target areas, and mineral resources), as well as the 1:1,500,000 geological and mineral map of the four Central Asian countries. The spatial database is built on the ArcGIS platform, providing fundamental data support for regional metallogenic regularity research, resource potential assessment, strategic prospective area delineation, and the compilation of various thematic maps. The database is archived in file geodatabase (GDB) format, with accompanying materials including ArcGIS project files (MXD) and raster map files (JPG). Additionally, a variety of common graphic formats such as PDF, TIF, and EPS can be generated as required. The geological and mineral data of the China Xinjiang-Central Asia Corridor adopts the Lambert Conformal Conic Projection, with the central meridian set at 67° east longitude and two standard parallels at 30° north latitude and 50° north latitude respectively. To facilitate data modification and improvement, a large volume of remote sensing data has been utilized, including ETM+, OLI, ASTER, and Worldview imagery, as well as 90m, 30m, and 12.5m DEM data. Regarding data quality: To meet the requirements of Pan-Third Pole regional metallogenic regularity research, geological and mineral map compilation, and metallogenic prediction map production, the data has been edited, processed, and supplemented in terms of spatial accuracy, logical consistency, and data integrity. Specific work includes: 1) Vectorization: A substantial amount of vectorization work has been carried out based on the aforementioned source materials to supplement areas with missing digital data. Polygon and line features are merged or split according to the update level of the source materials, and all vectorization tasks are completed in compliance with the scale accuracy requirements specified in relevant Chinese national standards; 2) Topology correction: Eliminating topological errors such as overlapping polygons and empty areas; 3) Attribute structure optimization and content supplementation: Focusing on the objectives of regional metallogenic regularity research, geological and mineral map compilation, and metallogenic prediction map production, and in accordance with relevant Chinese national specifications combined with specific source materials and data content, a corresponding data model has been established. The attribute structures of geological body, tectonic, and mineral feature classes have been improved, and relevant attribute information has been fully populated; 4) Data refinement: Building on the above data processing work and combining with the latest research findings and understandings of the Pan-Third Pole region, relevant geological contents within the study area have been further revised and improved. In terms of data application achievements and prospects: The Central Asian Four-Country Formation Facies Database primarily supports regional metallogenic regularity research in the four Central Asian countries of the Pan-Third Pole region, important metallogenic belts, and national-level study areas, as well as the compilation of the 1:1,500,000 Central Asian Four-Country Formation Facies maps.
