Database of 1∶50 000 Mineral Geological Map of the Suolong Map-sheet in Zhaishang–Mawu Gold Deposit, Minxian County, Gansu Province

The 1∶50 000 mineral geological map of the Suolong Map-sheet (I48E010011) inZhaishang–Mawu Gold Deposit in Minxian County, Gansu Province was developed inaccordance with the Technical Requirements of Solid Mineral Geological Survey (1∶50 000)and other unified standards and requirements in the geological industry, during which theresults obtained from previous 1∶50 000-scale regional geological surveys and 1∶50 000-scale regional mineral surveys were fully utilized. Meanwhile, the digital mapping system wasadopted for field geology-specific mapping, and indoor map compilation was conducted alongwith field mapping. In this map, the sedimentary suite types of the pre-Devonian Wujiashanand Dacaotan Formations, Carboniferous Badu Formation, and Permian Shilidun Formationare reclassified, the formation epochs of the intrusions are classified into Late Triassic andEarly Permian, and the evolutionary sequence of magmatic rocks is established. The goldmetallogenesis in this Map-sheet is closely related to Permian strata, and most deposits (oreoccurrences) occurred in clastic rocks of the Shilidun Formation with relatively developedfissures. The database of the 1∶50 000 mineral geological map (also referred to as theDatabase) includes the data of seven stratigraphic units and two stages of magmatic rocks, andcovers 212 polished thin sections, 192 chemical samples, 486 bedrock spectra, 2 793 soilsamples, two samples for Ar/Ar dating, eight samples for fluid inclusion thermometry, and 15samples for petrochemical analysis. Meanwhile, three gold ore bodies and one goldmineralized point were newly discovered in the study area, with estimated (334) gold of 5.32tonnes. Having a data size of about 17.4 MB, the Database fully reflects the demonstrationresults of 1∶50 000 mineral geological surveys, and could provide references for mineralresource research and energy exploration in this Map-sheet area.
