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 Geological Survey (DD 2019-02), during which the results of previous 1∶50 000 regional geological surveys were fully utilized. With mineralization types as the main line, this project focused on mineral and geology-specific mapping based on a preliminary study and mainly researched metallogenic factors. Meanwhile, the presentation of geology-specific mapping results was actively explored and innovated, the stratigraphic sequences of the Shiren Town map-sheet were basically ascertained, and the sedimentary rock suites, intrusion suites, and metamorphic rock suites were determined in detail. The map was completed by adding geographic data and mineral resource information to the suite-tectonic map, highlighting the expression of metallogenic information. The database of the map (also referred to as the Database) contains a mineral geological vector map in MapGIS format, whole-rock petrogeochemical data of seven samples, petrogeochemical data of major, trace, and rare earth elements of 20 samples, and zircon U–Pb isotopic dating data of 16 samples. Besides, it includes the data of 13 gold and polymetallic deposits, whose genetic types are quartz vein and alteration types. The total amount of resource reserves is 1098.41×104 t, and that of gold is 49 989 kg, with the average Au grade of 4.55 g/t. With a data size of about 80.70 MB, the database fully reflects the results of 1∶50 000 mineral and geology-specific mapping, thus providing basic geological bases and prospecting direction for future strategic actions on prospecting breakthroughs.
