摘　　要：吉林省通化县爱国铅锌矿床地处于通化-长白成矿带的西段。该矿床研究程度极低,其地质特征和矿床成因的研究,可提高矿床研究程度,并为矿区深部及区域铅锌矿找矿提供新思路。铅锌矿体主要赋存古元古代集安岩群蚂蚁河岩组NEE向断裂构造中,直接顶板为条痕状花岗杂岩,底板为黑云变粒岩,蚀变和铅锌矿化产于NEE向断裂破碎带中。金属矿物主要是方铅矿、闪锌矿,脉石矿物为石英、方解石、萤石、重晶石,围岩蚀变为中低温矿物组合;矿床成因类型应属中低温热液型铅锌矿床。The Aiguo lead-zinc deposit in Tonghua County,Jilin Province is located in the western section of the Tonghua-Changbai metallogenic belt.The research level of this deposit is extremely low,and the study of its geological characteristics and genesis can improve the research level of the deposit and provide new ideas for the exploration of lead-zinc deposits in deep mining areas and regions.The lead-zinc ore body mainly occurs in the NEE trending fault structure of the Mayihe Rock Formation in the Paleoproterozoic Ji an Rock Group.The direct roof is a striated granite complex,and the floor is biotite granulite.The alteration and lead-zinc mineralization occur in the NEE trending fault fracture zone.The main metallic minerals are galena and sphalerite,while the vein minerals are quartz,calcite,fluorite,and barite.The surrounding rock has been altered into a combination of medium and low-temperature minerals;the genesis type of the deposit should belong to the medium low temperature hydrothermal lead-zinc deposit.
