摘　　要：集安群地层主要分布在通化南部—集安一带,大地构造位于华北地台、辽吉台隆东部。通过对比和分析前人资料,从地层的沉积建造、岩石组合、构造及岩浆岩及其与成矿的关系入手,根据集安群的成矿地质背景、控矿条件和矿床(点)的分布特征,总结了其成矿规律。集安群地层中金(银)、铅、锌多金属矿床具有复成因、多期次成矿的特点,其成矿过程经历了初始矿源层的形成—改造矿源层—构造岩浆岩热事件富集—矿体就位。本文按成矿预测标志,圈定了集安群找矿远景区。Jian Group strata are mainly distributed in the southern region of Tonghua,Jilin Province,and tectonic system is located in the North China platform,eastern part of Liao-Ji anteclise.Through the contrast and analysis of previous material,and based on the strata of sedimentary formation,rock combination,relationship of structure and magmatic rocks and the ore-forming,ore-forming geological setting,ore-controlling conditions and ore deposits（points） distribution characteristics,summarized the ore-forming regularities,showing composite gensis,multiphase metallogenic characteristics of gold（silver）,lead,zinc,polymetallic ore deposit in Jian Group strata,its metallogenic process underwent formation of initial beds-transformation of beds-magmatic hot event enrichment-emplacement of ore bodies.This paper proposed criteria for ore prospecting and defined the metallogenic ore-hunting prospect areas.
