摘　　要：石芒坑金矿位于泾县黄村镇,是近年来在皖南地区金矿找矿的新发现。本文通过对石芒坑金矿详查工作取得的第一手野外资料和相关测试资料进行分析研究,简要分析其成矿作用过程,初步认为:石芒坑金矿形成于燕山晚期,成因类型为脉状中低温热液型,成矿作用经历了高温闪锌矿-黄铜矿固溶体分离成矿阶段、中低温金及铜多金属成矿阶段和后期风化氧化成矿作用阶段;矿区深部存在隐伏岩体的可能。为在该地区寻找类似的金矿床、扩大本矿床深部找矿空间提供借鉴。The Shimangkeng gold deposit,located in Huangcun Town,Jing County,is a new one discovered in southern Anhui in recent years.Based on analysis of the first-hand field data and relevant test results obtained from the detailed survey of the deposit,this paper briefly analyzes its mineralization process and preliminarily concludes that the gold deposit was formed in the late Yanshanian period,and it is genetically a veined medium-to low-temperature hydrothermal deposit,which has experienced high-temperature sphalerite-chalcopyrite solid solution separation,medium-to low-temperature gold and copper polymetallicmineralization and lateweathering oxidation mineralization,and a concealed rock mass is possibly deep-seated in the mineral district,providing a reference for exploration in the depth of this deposit and beyond in the area.
