1∶50 000 Mineral and Geological Map Database of Zangjiazhuang Map-sheet, Shandong Province

The 1∶50 000 mineral and geological map of Zangjiazhuang Map-sheet(J51E016004), Shandong Province was prepared according to applicable industry standardssuch as Technical Requirement of 1∶50 000 Solid Mineral Geological Survey (DD 2019-02)and Spatial Database for Digital Geological Map (DD 2006-06), during which the results ofrelevant 1∶50 000- and 1∶200 000-scale regional geological surveys were fully adopted. Inaddition, a digital mapping system was applied to acquire data in the field, and indoor mappreparation was conducted in combination with field survey of key survey sites. The data in the1∶50 000 mineral and geological map database of Zangjiazhuang Map-sheet, ShandongProvince (also referred to as the Database) was individually stored according to four types ofclasses, namely feature classes, complex classes, object classes and independent featureclasses. In this paper, a new polymetallic metallogenic belt located in Qixia, Yantai City wasproposed, i.e., the Gaojia–Xiangkuang–Xingjiashan polymetallic metallogenic belt. Thismetallogenic belt, with Mesozoic acid intrusions as metallogenic intrusions, is under thecontrol of the intersection of the EW- and NNE-trending faults. LA-ICP-MS zircon U-Pbdating of the metallogenic intrusions in typical Xiangkuang polymetallic deposits indicates thatthe metallogenic age of the metallogenic intrusions is 127.91±0.58 Ma, providing new credibledata for research into the metallogenic ages and rules of the polymetallic deposits inZangjiazhuang Map-sheet. The Database covers the data of five ages and 25 mineral deposits,including two copper ore occurrences and one gold mineralized point that were newlydiscovered. Meanwhile, two prospecting target areas were determined and six predictedminimum prospecting target areas were delineated. Furthermore, the resources of Au, Ag, Pband Zn in the new polymetallic metallogenic belt were predicted to be 10 962 kg, 499.638 t,141 437 t and 230 011 t, respectively. The Database could provide basic data for the geologicalprospecting in Zangjiazhuang Map-sheet, as well as data sources for information- and network-oriented construction of geology.
