摘　　要：根据东秦岭不同构造发展阶段的沉积建造和岩石组合,划分成矿系统与成矿组合如下:(1)前长城纪陆核活动性边缘沉积成矿系统:舞阳铁成矿组合,小秦岭金成矿组合;(2)中、新元古代被动大陆边缘成矿系统:熊耳山铜铅锌成矿组合,神洞沟喷流沉积锰铅成矿组合,维摩寺铅锌成矿组合;(3)早加里东期构造体制转换期成矿系统:刘山崖铜锌成矿组合,围山城金银成矿组合,秋树湾斑岩铜钼成矿组合;(4)古生代活动大陆边缘成矿系统:公馆汞锑成矿组合,银洞子银铅、大西沟菱铁矿-重晶石成矿组合;(5)中生代陆内碰撞造山成矿系统:燕山期中酸性小岩体钼钨铅锌金银成矿组合,改造热液型金银铅锑成矿组合。According to the sedimentary formations and rock associations in different tectonic evolution stages in the East Qinling,the metallogenic systems and their corresponding metallogenic assemblages may be distinguished as follows :(1)the sedimentary metallogenic system on the active continental margin of the pre-Mesoproterozoic(Changchengian)continental nucleus :Wuyan g Fe metallogenic assemblage and Xiaoqinling Au metallogenic assemblage;(2)the metallogenic system on the Meso -and Neoproterozoic passive continental margin:Xiong'ershan Cu-Pb-Zn metallogenic assemblage,Shendonggou exhalation-sedimentary Mn-Pb metallogenic assemblage and Weimosi Pb-Zn metallogenic assemblage;(3)the metal-logenic system in the transition stage of the early Caledonian tectonic system:Liushanya Cu-Zn metallo-genic assemblage,Weishancheng Au-Ag metallogenic assemblage and Qiushuwan porphyry Cu-Mo metal-logenic assemblage;(4)the metallogenic system on the Paleozoic active continental margin:Gongguan Hg-Sb metallogenic assemblage and Yindongze Ag-Pb and Daxigou siderite-barite metallogenic assemblage;and(5)the metallogenic system in the Mesozoic intracontinental collisional orogenic belt:Mo-W-Pb-Zn-Au-Ag metallogenic assemblage associated with small Yanshanian intermediate-acid intrusions and mod-ified hydrothermal Au-Ag-Pb-Sb metallogenic assemblage.
