摘　　要：本文简要分析了东北地区区域成矿地质背景.从金成矿物质来源的同一性和继承性出发划分出3个金成矿系统:(1)变质岩金成矿系统,以变质岩含金建造为物源基础,形成了多种矿床类型组合;(2)中(新)生代陆相火山热液金成矿系统,矿床产出于中(新)生代火山岩系分布区,成矿物质主要源于火山岩系;(3)第四纪砂金成矿系统.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.
