ANALYSIS OF GOLD METALLOGENIC SYSTEMS IN NORTHEAST CHINA

Based on the identity and successiveness of the ore forming material sources,three gold metallogenic systems in Northeast China are classfied as follows:(1)the metallogenic system of metamorphic gold deposits,which is on the basis of material sources of auriferous formation and composed of various ore type assemblages;(2)the gold metallogenic system of Mesozoic (Cenozoic) volcanic hydrothermal fluid;and(3)the Quaternary placer gold metallogenic system.
