Database of 1∶50 000 Mineral Geological Map of the Shiren Town Map-sheet, Jilin Province

The 1∶50 000 mineral geological map of the Shiren Town map-sheet(K52E013003) in Jilin Province was prepared by adopting indoor and field mapping(compilation) according to the Technical Requirement of 1∶50 000 Solid Mineral GeologicalSurvey (DD 2019-02), during which the results of previous 1∶50 000 regional geologicalsurveys were fully utilized. With mineralization types as the main line, this project focused onmineral and geology-specific mapping based on a preliminary study and mainly researchedmetallogenic factors. Meanwhile, the presentation of geology-specific mapping results wasactively explored and innovated, the stratigraphic sequences of the Shiren Town map-sheetwere basically ascertained, and the sedimentary rock suites, intrusion suites, and metamorphicrock suites were determined in detail. The map was completed by adding geographic data andmineral resource information to the suite-tectonic map, highlighting the expression ofmetallogenic information. The database of the map (also referred to as the Database) contains amineral geological vector map in MapGIS format, whole-rock petrogeochemical data of sevensamples, petrogeochemical data of major, trace, and rare earth elements of 20 samples, andzircon U–Pb isotopic dating data of 16 samples. Besides, it includes the data of 13 gold andpolymetallic deposits, whose genetic types are quartz vein and alteration types. The totalamount of resource reserves is 1 098.41 ×104 t, and that of gold is 49 989 kg, with the averageAu grade of 4.55 g/t. With a data size of about 80.70 MB, the database fully reflects the resultsof 1∶50 000 mineral and geology-specific mapping, thus providing basic geological bases andprospecting direction for future strategic actions on prospecting breakthroughs.
