1) The spatial scope of this database covers: ① Xinjiang, China; ② Central Asia (Kazakhstan, Kyrgyzstan, Tajikistan, Uzbekistan). The main data contents include: ① 1:5 million scale geological dataset (geological bodies and structures); ② metallic mineral resources dataset (deposits, mineral occurrences, mineralization points). The primary accompanying map is the Geological and Mineral Resources Map of the Xinjiang-Central Asia Corridor (1:5 million scale). The spatial database is built on the ArcGIS platform, providing basic data support for regional metallogenic regularity research, resource potential assessment, strategic prospective area delineation, and compilation of various thematic maps. The database is stored in File Geodatabase (.GDB) format, and the accompanying materials include ArcGIS project files (MXD) and raster images (JPG). Additionally, various common graphic formats (PDF, TIF, EPS, etc.) can be generated upon request. The Geological and Mineral Resources Data of the Xinjiang-Central Asia Corridor adopts the Lambert Conformal Conic Projection, with the central meridian set at 75°E, and two standard parallels at 30°N and 50°N respectively.
2) Data sources and processing methods: Basic geological data primarily originates from the 1:5 million scale Asia Geological Map compiled by Academician Ren Jishun (2015). Mineral data is sourced from multiple channels: results of the National Mineral Resource Potential Evaluation Project (2012), the Central Asian Mineral Database and thematic maps from the Natural History Museum in London, UK (2014), the Afghanistan dataset of the U.S. Geological Survey (2008), relevant data from geological survey departments of countries in the region, and academic papers and monographs related to regional mineral resources. Furthermore, a large volume of remote sensing data has been utilized for data revision and improvement, including image data from ETM+, OLI, ASTER, Worldview, as well as DEM data with resolutions of 90m, 30m, and 12.5m.
3) Data quality description: To meet the needs of metallogenic regularity research in the Pan-third Pole region, as well as the compilation of geological and mineral maps and metallogenic prediction maps, the data has been edited, processed, supplemented and optimized in terms of spatial accuracy, logical consistency and data integrity. The specific work contents are as follows: ① Vectorization: A substantial amount of vectorization work has been conducted based on the aforementioned materials to supplement areas with missing digital data. Meanwhile, polygon and line features are merged or split according to the update status of the source data. All vectorization work complies with the scale accuracy requirements specified in China's relevant technical specifications; ② Topology processing: Topological errors such as overlapping polygons and void areas are eliminated; ③ Improvement of feature attribute structure and supplementation of attribute content: Centered on the goals of regional metallogenic regularity research, and compilation of geological, mineral and metallogenic prediction maps, a corresponding data model was established in accordance with China's relevant technical specifications, combined with specific source data and content. The attribute structures of geological body, structural and mineral feature classes were improved, and corresponding attribute filling work was completed; ④ Based on the above data processing results, combined with the latest research findings and understandings of the Pan-third Pole region, further revisions and optimizations were made to relevant geological contents within the study area.
4) Data application achievements and prospects: The Geological and Mineral Resources Dataset of the Xinjiang-Central Asia Corridor is mainly used for metallogenic regularity research, and the compilation of geological, mineral and metallogenic prediction maps, for the Xinjiang-Central Asia Corridor region, important metallogenic belts and national-level regional studies, with a map scale of 1:5 million (Xinjiang-Central Asia Corridor, China).
