湖南水口山矿田康家湾铅锌金银矿床第二找矿空间地质特征及找矿方向

康家湾铅锌金银矿为湖南常宁水口山矿田内大型隐伏矿床,近年在其东部地质找矿取得了突破,探寻到了第二找矿空间,先后在地尺355～719m中段发现大小矿体11个。通过与第一找矿空间对比研究,结合矿山生产实践,总结了矿床第二找矿空间地质特征、控矿因素,并进行成矿预测。认为康家湾矿在硅化破碎角砾岩带(QB)及下部碳酸盐岩地层中仍具良好找矿前景,同时深部具寻找矽卡岩型铅锌矿床潜力。

Geological characteristics and prospecting direction of the second prospecting space of the Kangjiawan lead-zinc-gold-silverdeposit in Shuikoushan orefield,Hunan Province

The Kangjiawan lead-zinc-gold-silver mine is a large-scale concealed deposit in the Shuikoushan ore field in Changning,Hunan. In recent years,it has made breakthroughs in its eastern geological prospecting and explored the second prospecting space. By comparing with the first prospecting space,it is found that the geological characteristics of the deposit are different. Through comparative research,field cataloging and test analysis,combined with mine production practices,this paper summarizes the geological characteristics and ore-controlling factors of the second ore prospecting deposit,and conducts metallogenic prediction. Eleven large and small are bodies were found at 355-709 meters in the underground It is believed that the Kangjiawan mine still has good prospecting prospects in the silicified fractured breccia zone (QB) and the lower carbonate rock strata,and the potential of the skarn-type lead-zinc deposit is deep.
