This database covers the following spatial scopes: ① the Qinghai-Tibet Plateau and Xinjiang, China; ② Central Asia (Kazakhstan, Kyrgyzstan, Tajikistan, Uzbekistan); ③ West Asia (Pakistan, Afghanistan, Iran); ④ Southeast Asia (Thailand, Vietnam, Laos, Myanmar, Cambodia). The main data contents include: ① 1:5,000,000-scale geological data (geological bodies and structures); ② metallic mineral data (ore deposits, mineral occurrences, mineralization spots). The primary cartographic product is the Pan-Tertiary Geological and Mineral Map (1:5,000,000).

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 the compilation of various thematic maps. The database is stored in File Geodatabase (.GDB) format. The cartographic files include ArcGIS project files (MXD) and raster maps (JPG), and various common graphic formats such as PDF, TIF, and EPS can also be generated upon request.

The entire Pan-Tertiary region (1:5,000,000 scale) adopts the Lambert Conformal Conic Projection, with the central meridian at 84°E and the two standard parallels at 20°N and 55°N respectively.

Data Sources and Processing Methods: The basic geological data mainly originates from the 1:5,000,000-scale Geological Map of Asia compiled by Academician Ren Jishun (2015). The metallic mineral data is sourced from multiple channels, including the results of the National Mineral Resource Potential Evaluation Project (2012), the Central Asian Mineral Database and thematic maps of the Natural History Museum, London, UK (2014), the Afghanistan dataset of the U.S. Geological Survey (2008), relevant data from geological survey agencies of countries in the region, and papers and monographs related to mineral resources in the region. Additionally, a substantial amount of remote sensing data has been utilized for data modification and improvement, including ETM+, OLI, ASTER, Worldview and other satellite image data, as well as 90m, 30m, and 12.5m resolution DEM data.

Data Quality Assurance: To meet the requirements of regional metallogenic regularity research, and the compilation of geological, mineral, and metallogenic prediction maps in the Pan-Tertiary region, editing, processing, and supplementary refinement have been conducted to ensure spatial accuracy, logical consistency, and data integrity. The specific work includes: ① Vectorization: A large volume of vectorization work has been carried out based on the aforementioned materials to supplement digital data-deficient areas (Iran and Pakistan). Meanwhile, polygon and line features have been merged or split according to the update status of the source data. All vectorization work was completed in compliance with the scale accuracy requirements specified in relevant Chinese national standards; ② Topology Correction: Eliminate topological errors such as overlapping polygons and empty areas; ③ Improvement of Feature Attribute Structure and Supplementary Attribute Information: Centered on the goals of regional metallogenic regularity research, and the compilation of geological, mineral, and metallogenic prediction maps, and in accordance with relevant Chinese specifications, combined with specific source data and materials, a corresponding data model was established. The attribute structures of geological body, structure, and mineral feature classes were optimized, and the corresponding attribute information was fully filled out; ④ Further Revision and Improvement: Based on the above data processing results, combined with the latest research findings and understandings of the Pan-Tertiary region, relevant geological contents within the region have been further revised and improved.

4) Data Application Achievements and Prospects: The Pan-Tertiary Geological and Mineral Database primarily serves the research on regional metallogenic regularity, and the compilation of geological, mineral, and metallogenic prediction maps for the entire Pan-Tertiary region, key metallogenic belts, and national-level regions, with a map scale of 1:5,000,000 for the entire Pan-Tertiary region.
