摘　　要：铜街-曼家寨矿段探明锌、锡、铟等金属资源量均达超大型规模。本文从“东西方向”、“南北方向”、“垂直方向”,对Zn、Sn、Cu元素进行分布规律研究。结果表明:东西方向Zn元素由西至东含量逐渐变低,Cu元素逐渐变高,Sn元素在铜街及曼家寨北部由西至东逐渐变高,南部东西方向趋于平稳;南北方向Zn、Sn元素显示两端高,中间低;垂直方向Sn元素由地表至深部,品位增加,Zn元素由地表至深部,品位降低。可为本区矿床成因机制研究提供理论基础,对该区锡锌铜矿勘查及找矿工作具有一定指导意义。The explored Zn,Sn,In,etc metallic resources are super-magnitude scale in Tongjie-Manjiazhai Ore Block.In this paper,we have the researches on distribution rule of Zn,Sn,Cu elements in EW,NS and vertical directions,showing in the EW direction,Zn progressively decreases Cu progressively increases fromW to E,Sn in the N part of Tongjie and Manjiazhai progressively increases fromW to E,in the S part to be stable in EW direction;in NS direction,Zn,Sn show increases to 2 ends,decreases in the middle;in the vertical direction,Sn grade increases from surface to the deep,Zn grade decreases from surface to deep,which can provide theory foundation for the genesis mechanism study of ore deposit,with some guide significance in Sn,Zn,Cu deposit exploration and prospecting in this area.
