摘要
在前人研究和地质找矿基础上,对水口山矿田地质成矿成因、特点、类型讨论,对影响找矿布置的问题进行剖析,综合水口山矿田内各矿床地质特征,研究矿床矿石成分、结构构造、围岩蚀变、矿体产状、围岩岩性等特点,认为水口山矿田是岩浆期后热液作用形成的浅成中-低温热液矿床。老鸦巢、鸭公塘矿床,产状近直立的铅锌矿体和含金黄铁矿矿体位于浅成低温热液的中心,康家湾铅锌金银矿是一个远离成矿母岩的矿床。岩浆侵入活动和潜火山作用对成矿有着重要作用。第二找矿空间内开展矽卡岩型矿床的勘查是水口山矿田下一步深部找矿方向。
On the basis of previous studies and geological prospecting,this paper discusses the genesis,characteristics and types of geological mineralization in Shuikoushan orefield,analyzes the problems affecting the prospecting layout,and studies the ore composition,structural structure,wall rock alteration,ore body occurrence,wall rock lithology and other characteristics of Shuikoushan orefield by integrating the geological characteristics of various deposits in Shuikoushan orefield The epithermal deposits formed in the middle and low temperature of the ore body.Laoyachao and Yagongtang deposits are located in the center of epithermal.Kangjiawan Pb Zn Au Ag deposit is far away from the ore-forming parent rock.Magmatic intrusion and subvolcanism play an important role in mineralization.The exploration of skarn deposits in the second prospecting space is the next deep prospecting direction of Shuikoushan ore field.
