摘　　要：康家湾铅锌矿是湖南省水口山矿田大—超大型隐伏矿床,近十多年来,矿床东部深处进行了大量地质勘查工作,矿床地质特征发生了变化,发现了第二找矿空间,新增铅锌资源储量规模达到中型。通过系统总结矿区地质特征,全面分析成矿地质条件与控矿因素,提出了“背斜+两刀”的成矿模型,升华了水口山地区铅锌矿床找矿理论,对成矿有利靶区进行预测,指明下步找矿主攻方向。研究结果认为硅化破碎角砾岩带仍然是重要的找矿标志,兼顾探寻碳酸盐岩古溶洞、构造裂隙带中发育的小而富铅锌矿体,深部寻找矽卡岩型盲矿体依然潜力较大,铜等高温元素可作为今后重点勘查方向。同时,矿区东部新盟山等地具有较大找矿潜力。Kangjiawan lead-zinc deposit is a large to super-large scale deposit concealed in Shuikoushan ore field.In the past more than 10 years,a lot of geological exploration work has been carried out in the eastern part of the deposit,the second prospecting space has been found,and the newly-enlarged lead-zinc resources have reached up to a medium scale deposit.For the systematic summary of the geological characteristics of the deposit and comprehensive analysis of the ore-controlling factor,the paper puts forward the"anticline+two knives"metallogenic model,sublimates the prospecting theory in the Shuikoushan area,and points out the next prospecting direction for the mineralization exploration.According to the research result,silicified and broken breccia belt is still the key prospecting direction,the exploration of small rich orebodies in the ancient karst cave and structural fracture of carbonate rocks are taken into account,and there is a great exploration potential for the skarn type deposit in the deep place.Copper and other high-temperature elements can be taken as the key exploration direction in the future.At the same time,there is a great prospecting potential at Xinmengshan and other places in the east area of the deposit.
