摘　　要：水槽子铜矿的成因与湖泊沼泽相含煤碎屑岩建造紧密相关 ,多个呈似层状、透镜状的矿体 ,均赋存于该沉积序列中。成岩期即为主成矿期 ,后期含矿热液叠加使局部变富或构成工业矿体。系统的工程揭控显示 :含矿层位卷入了后期构造挤压变形 ,但并没有破坏矿体形成的原始踪迹。矿床成因应属 (沉积 )层控热液叠加矿床类型。最后 ,笔者提出在该区寻找同类矿床的新思路与找矿方向。The genesis of Shuicaozi Cu deposit has a close relation with the coal bearing clastic rock formation of lacustrine bog facies.Many stratoid,lenticular orebodies are occurred in this sediment sequence.The diagenetic period is the major metallogenetic stage.The local enrichment of industrial orebody is formed by the posterior ore bearing hydrothermal superimposition.The ore bearing horizon had been involved in the later structural compression deformation,but the original trace of orebody formation was not destroyde.The genesis of ore deposit must belong to hydrothermal superimposition (sedimentary)stratabound type.The new prospecting direction of the same ore deposit in this area is put forward in this paper.
