【Abstract】 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.更多还原
