METALLOGENIC SERIES AND REGIONAL METALLOGENIC PEDIGREE OF GOLD DEPOSITS IN JILIN PROVINCE

By summarizing the metallogenic regularity of gold deposits in Jilin Province, the study provides a new reference for gold prospecting in the area. Based on the metallogenic series theory and method, the main gold deposits in Jilin are assigned to 6 metallogenic series, including 11 metallogenic subseries with 19 deposit types. Combined with the development history of regional tectonics in Jilin, the paper discusses the spatiotemporal evolution rule of gold metallogenesis, and establishes the regional metallogenic pedigree of gold deposits. The results show that the formation of gold deposits in Jilin is unbalanced in time and space, with the most important gold mineralization period in Yanshanian, followed by Wutaian, Zhongtiao, Variscan and Indosinian periods, and the most significant gold metallogenic belt of Jiapigou metallogenic belt, followed by Ji'an-Laoling, central Jilin, and Yanbian metallogenic belts.
