Abstract: The Zhaochuan Map-sheet (K50E020006) area is located in the eastern part of Zhangjiakou–Xuanhua region of Hebei province and the middle section of the northern margin of the North China craton. It is one of the important gold fields in China. The 1∶50 000 mineral geological map database of the Zhaochuan Map-sheet was compiled in accordance with the Technical Requirements of Solid Mineral Geological Survey (1∶50 000) (DD 2019−02) and other applicable industrial standards. The survey work involves specific geological mapping covering an area of 379.93 km², measured geological routes totaling approximately 315 km in length, ore spot checks and anomaly checks at about 15 points, three groups of U–Pb ages (390–370 Ma, 234 Ma and 140–120 Ma), and six groups of whole-rock analytical data. Through comprehensively analysing field measurement data of geological points, geological routes and geological boundaries, and previous regional geological survey records, the boundaries of geological units were redelineated, and the corresponding feature layers were established. Meanwile, the Meso–Neoarchean, Mesoproterozoic and Mesozoic strata in the Zhaochuan Map-sheet were redivided, the Archean to Mesozoic magmatic rocks were generalized, the spatio-temporal evolution sequence of the magmatic rocks and metallogenesis was determined, and a “three-in-one” ore prospecting prediction geological model and an integrated geological, geochemical, geophysical and remote-sensing ore prospecting prediction model were then established. The database has a high reference value for the deployment of mineral exploration activities in the area, and could also provide service for the local natural resource departments in the field of the land space planning and ecological civilization.
