摘要
水口山矿田内的花岗质岩石是由潜火山作用形成的包括浅成侵入的花岗闪长质岩石、次火山侵入的英安对岩质岩石及与其伴生的隐爆角砾岩三个岩相的岩石组合——花岗质潜火山杂岩、其成因属壳幔混熔过渡型花岗岩。这类杂岩与银、铅、锌、金、银多金属成矿的密切关系在水口山矿田得到充分体现。矿田内多金属成矿符合多因复成成矿模式和多位一体复合成矿模式。重视潜火山杂台与有色、贵重金属成矿关系的研究，运用多因复成成矿理论在矿田内进一步扩大找矿，前景良好。
Granitic sub-volcanic complex in Shuikoushan ore field consists of the shallow- level-int rudedgranodiorite, sub-volcanic dacite-porphry and crypto-expleded breccia. It is of a transitional typeof granite formed from miscibly melted crustal and mantle materials. Close relation of the complexand Cu, pb, Zn, Au, Ag polymetal minerAlization is typified in Shuikousban ore field. The mineralization is coincided with multi factor superimposition medel and multi-emplacement combinationmodel. CarefuI study of the relation between the complex and mineralization would benefit thefurther ore-searching of nonferro-metals and precious metals in the field.
