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 11 mineralized occurrences being verified, and 1622 stream sediment samples being collected; 1623 physical points of gravity survey were finished, three groups of zircon U–Pb dating samples and more than 80 pieces of fluid inclusion samples were tested, the 1∶50 000-scale geological map of Chongli Map-sheet, Hebei Province was compiled, and the correspondent database was established. Relevant mineralization information, including Yanshanian magmatic rocks and relevant dykes, alkaline complexes and Guzuizi Formation, mineralization and alteration, etc. were highlighted, Mesoarchean and Neoarchean metamorphogenic plutons within the Chongli Map-sheet area were delineated, and Hercynian, Indochina and Yanshanian magmatic rock formation types were divided; Zhangjiakou Formation volcanic rocks were divided into seven formation types, and Guzuizi Formation metamorphic rocks were divided into three formation types; the mineralized geologic bodies, mineralized structures and mineralized structural planes, mineralization characteristic indicators of gold deposits within the area were summarized systematically. This database provides basic data support for gold prospecting in the area, favors extracting geological and structure–formation information of target gold horizons and is of reference value to subsequent mineral exploration deployment.
