1) Data Content: The spatial coverage of this database includes four regions: ① the Qinghai-Tibet Plateau and Xinjiang of 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 are as follows: ① 1:5 million geological dataset (geological bodies and structures); ② 1:1 million national geological and mineral datasets (geological bodies, structures, minerals); ② metallic mineral dataset (ore deposits, mineral occurrences, mineralization points); ④ Xinjiang-Central Asia metallogenic geological background dataset (rock assemblages, tectonic divisions, metallogenic belts, prospective areas, target areas, minerals). The main maps include: Pan-Tertiary geological and mineral map (1:5 million), Geological and Mineral Map of Four Central Asian Countries (1:1.5 million), Geological and Mineral Map of Pakistan (1:1 million), Geological and Mineral Map of Afghanistan (1:1 million), Geological and Mineral Map of Iran (1:1 million), Geological and Mineral Map of Xinjiang-Central Asia Corridor Belt of China (1:2.5 million), Metallogenic Regularity Map of Xinjiang-Central Asia Corridor Belt of China (1:2.5 million), and Geological and Mineral Map of Qinghai-Tibet Plateau of China (1:1.5 million). 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 stored as File Geodatabase (.GDB), and the maps include engineering files (MXD) and raster images (JPG). Various common graphic formats (PDF, TIF, EPS, etc.) can also be generated upon request. The Pan-Tertiary full region (1:5 million) adopts the Lambert Conformal Conic Projection, with the central meridian at 84°E and two standard parallels at 20°N and 55°N. The geological and mineral data of the Xinjiang-Central Asia Corridor Belt of China adopt the Lambert Conformal Conic Projection, with the central meridian at 75°E and two standard parallels at 30°N and 50°N. The 1:1 million geological and mineral datasets of major countries in Central Asia and West Asia adopt the Lambert Conformal Conic Projection, with the central meridian and standard parallels determined specifically according to the geographic location of each country.
2) Data Sources and Processing Methods: Basic geological data mainly come from the Asian Geological Map (1:5 million, 2015) compiled by Academician Ren Jishun, the Central Eurasian Tectonic Metallogenic Map and Geological Map (1:2.5 million, 2008), and geological maps (1:1 million) from geological survey departments of countries within the region; ② Mineral data mainly come from the results of the National Mineral Resource Potential Assessment Project (2012), the Central Asian 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 geological survey departments of countries within the region, and papers and monographs related to minerals in the region. In addition, a large amount of remote sensing data was used to modify and improve various data, including image data such as 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 Pan-Tertiary regional metallogenic regularity research, compilation of geological and mineral maps and metallogenic prediction maps, editing, processing, and supplementation were carried out in terms of spatial accuracy, logical consistency, and data integrity. The specific work includes: ① Vectorization: A large number of vectorization tasks were carried out based on the aforementioned data to supplement the areas lacking digital data (Iran, Pakistan). Meanwhile, polygon and line features were merged or split according to the update degree of the data. The vectorization work was completed in accordance with the scale accuracy requirements of relevant Chinese specifications. ② Topology processing: Topological errors such as overlapping polygons and empty areas were eliminated. ③ Improvement of feature attribute structure and supplementation of feature attribute content: Centered on the goals of regional metallogenic regularity research, compilation of geological and mineral maps and metallogenic prediction maps, and in accordance with relevant Chinese specifications, combined with specific data and contents, the corresponding data model was established, the attribute structures of geological body, structure, and mineral feature classes were improved, and the corresponding attribute filling work was completed. ④ Based on the above data processing contents, combined with the research results and latest understandings of the Pan-Tertiary region, relevant geological contents within the region were further modified and improved.
4) Data Application Achievements and Prospects: The Pan-Tertiary geological and mineral database mainly serves the regional metallogenic regularity research, compilation of geological and mineral maps and metallogenic prediction maps for the entire Pan-Tertiary region, important metallogenic belts, and national-level regions, with scales of 1:5 million (entire Pan-Tertiary region), 1:2.5 million (Xinjiang-Central Asia Corridor Belt of China), and 1:1 million (important metallogenic belts, national-level regions in Central and West Asia).
