摘　　要：刘山岩铜锌矿带位于东秦岭造山带之北秦岭褶皱带核部。矿体赋存于硅质—钠长石岩层中。自矿体中心向边缘存在黄铁矿—黄铜矿—方铅矿—重晶石—石英的相对矿物分带。经矿带物化探资料的综合研究认为,深部及外围有较大的找矿空间。文章从地质背景、成矿作用及地球物理、地球化学特征分析入手,对深部找矿前景作出了判断,以期为在刘山岩矿带及攻深找盲有所突破。Liushanyan Cu-Zn mineralization zone is located at the core part of the North Qingling drape strip of the East Qingling orogen. The orebody is in the rock layer of silicon and albite. There are mineral zones of pyrite-chalcopyrite-galena-barite-quartz from the orebody center to edge. Base on the integrated study of geophysical and geochemical information, it is proposed that there is prospecting space in the deep and periphery area. According to geological background, mineralization process, geophysical and geochemical feature, the paper has pointed out the propecting foreground of the deposit in order to get some achievement in the exploration of blind orebody in the depth.
