This database covers the spatial scope of the Coqen-Shenzha metallogenic belt (Gangdese-Himalayan orogenic system).
The main data contents include: the metallogenic regularity dataset of the Coqen-Shenzha Au-Cu-Fe-W-Mo metallogenic belt (covering rock assemblages, tectonic divisions, metallogenic districts, prospective areas, target areas, and mineral deposits), as well as the main maps: the metallogenic regularity map of the Coqen-Shenzha Au-Cu-Fe-W-Mo metallogenic belt at a scale of 1:1,000,000.
The spatial database is developed based on the ArcGIS platform, and 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 stored in ArcGIS File Geodatabase (.GDB) format. The map products include ArcGIS Map Documents (.MXD) and raster maps in JPG format, and a variety of common graphic formats (such as PDF, TIF, EPS, etc.) can be generated upon request.
The metallogenic regularity data of the Coqen-Shenzha Au-Cu-Fe-W-Mo metallogenic belt adopts the Lambert Conformal Conic Projection, with the central meridian at 86°E and the two standard parallels at 30°N and 33°N respectively.

Data sources and processing methods: Basic geological data mainly originate from the *Geological Map of Asia* (2015, 1:5,000,000 scale) compiled by Academician Ren Jishun, the Tectonic and Metallogenic Map and Geological Map of Central-Eurasia (2008, 1:2,500,000 scale), and geological maps (1:1,000,000 scale) from various regional geological survey departments.
② Mineral data mainly come from the results of the National Mineral Resource Potential Assessment Project (2012), relevant data and materials from various regional geological survey departments, and papers and monographs related to minerals in the region.
In addition, a large volume of remote sensing data has been utilized for data modification and improvement, including image data such as ETM+, OLI, ASTER, Worldview, as well as DEM data with resolutions of 90m, 30m, and 12.5m, etc.

Data quality description: To meet the requirements of metallogenic regularity research for the Coqen-Shenzha Au-Cu-Fe-W-Mo metallogenic belt, as well as the compilation of geological-mineral maps and metallogenic prediction maps, editing, processing, and supplementation have been carried out to improve data spatial accuracy, logical consistency, and data integrity.
Specific contents include: ① Vectorization: A large amount of vectorization work has been conducted based on the aforementioned materials to supplement areas lacking digital data. Meanwhile, polygon and line features are merged and split according to the update level of the source materials. The vectorization work is completed in compliance with the scale accuracy requirements specified in relevant Chinese national standards.
② Topology processing: Topological errors such as overlapping polygons and empty areas have been eliminated.
③ Optimization of feature attribute structures and supplementation of feature attribute contents: Focusing on the objective of compiling regional metallogenic regularity maps and metallogenic prediction maps, corresponding data models have been established in accordance with relevant Chinese national standards and combined with specific materials and data contents. The attribute structures of geological bodies have been optimized, and the attribute filling work for rock assemblages, tectonic divisions, and affiliated metallogenic belts has been completed.
Based on the above data processing contents, combined with the research findings and latest understandings of the Tibetan Plateau, relevant geological contents in the region have been further modified and improved.

Data application results and prospects: This database primarily serves metallogenic regularity research of the metallogenic belt and the compilation of metallogenic regularity maps at a scale of 1:1,000,000.
