Metallogenic series,metallogenic lineage and metallogenic evolution history of gold deposits in Liaodong-Jinan metallogenic belt
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 metal-logenic 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 mineraliza-tion lineage.According to four gold ore-forming periods of Neoarchean,Puleoproterozoic,Mesozoic and Cenozo-ic,the gold ore-forming evolution history of the southern and eastern Liaoning metallogenic belt was summa-rized.The identification of genetic type of gold deposits,the classification of metallogenic series,the establish-ment 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.
