1∶50 000 Mineral Geological Map Database of the Chongli Map-sheet, Hebei Province, China

According to Technical Requirement of Solid Mineral Geology Survey (1∶50 000)(DD 2019–02) as well as other industrial criteria and requirements, 379.93 km2 of 1∶50 000-scale geologic mapping of the Chongli Map-sheet, Hebei Province has been completed with 11mineralized occurrences being verified, and 1 622 stream sediment samples being collected;1 623 physical points of gravity survey were finished, three groups of zircon U–Pb datingsamples and more than 80 pieces of fluid inclusion samples were tested, the 1∶50 000-scalegeological map of Chongli Map-sheet, Hebei Province was compiled, and the correspondentdatabase was established. Relevant mineralization information, including Yanshanianmagmatic rocks and relevant dykes, alkaline complexes and Guzuizi Formation, mineralizationand alteration, etc. were highlighted, Mesoarchean and Neoarchean metamorphogenic plutonswithin the Chongli Map-sheet area were delineated, and Hercynian, Indochina and Yanshanianmagmatic rock formation types were divided; Zhangjiakou Formation volcanic rocks weredivided into seven formation types, and Guzuizi Formation metamorphic rocks were dividedinto three formation types; the mineralized geologic bodies, mineralized structures andmineralized structural planes, mineralization characteristic indicators of gold deposits withinthe area were summarized systematically. This database provides basic data support for goldprospecting in the area, favors extracting geological and structure–formation information oftarget gold horizons and is of reference value to subsequent mineral exploration deployment.
