摘　　要：辽东吉南成矿带位于渤海东陆块北部,金矿成矿地质条件优越。通过分析成矿带金矿资源情况,研究不同成矿作用所形成金矿的时空分布及地质特征,划分出与沉积作用有关、与岩浆作用有关及与变质作用有关的3个金矿成矿系列组合,以及5个成矿系列、12个成矿亚系列、18个矿床式。将大地构造单元、成矿时代及成矿区带与金矿成矿系列结合,建立了金矿成矿谱系,并按照新太古代、古元古代、中生代和新生代4个金矿成矿期,对辽东吉南成矿带金矿的成矿演化历史进行总结。研究成果可增强辽东吉南成矿带金矿成矿规律的研究程度,为在成矿区带内开展金矿研究提供基础资料。Liaodong-Jinan metallogenic belt is located in the northern part of the eastern Bohai Sea block,and the geological conditions for gold mineralization are superior.On the basis of analyzing the gold resources profile in the metallogenic belt,the authors analyzed the temporal and spatial distribution and geological characteristics of gold deposits formed by different mineralization processes.Then,3 gold metallogenic series associations,5 metallogenic series,10 metallogenic subseries and 18 deposit types were classified.The tectonic units,mineralization periods,and mineralization zones were combined with gold mineralization series to establish the gold mineralization lineage.According to four gold ore-forming periods of Neoarchean,Puleoproterozoic,Mesozoic and Cenozoic,the gold ore-forming evolution history of the southern and eastern Liaoning metallogenic belt was summarized.The identification of genetic type of gold deposits,the classification of metallogenic series,the establishment of metallogenic lineage and the research of evolution history would further enhance the research degree of gold mineralization regularity of Liaodong-Jinan metallogenic belt,and could provided basic data for future study of gold deposits in this metallogenic belt.
