摘　　要：对该区的矿床时空分布、矿床类型、成矿系列、成矿物化条件、矿源等进行了系统的研究总结。指出区内总体成矿地质背景为具有过渡型地壳特色的大陆复合型造山带 ,可划分为中元古代-古生代海盆同生沉积成矿、中生代大规模陆内俯冲造山体制后生热液成矿两个成矿阶段 ,具有盆地边缘控矿、动力学转换带成矿。A systematic study has been carried out on space time distribution, physiochemical condition for mineralization,metallogenic series, sources and types of deposits in the East Qinling Dabie orogenic belt which is considered to be a compound one controlling the regional mineralization with transitional crust. Two mineralization stages has been distinguished, one is Mesoproterozoic Palaezoic syndepositional mineralization in sea basins, the other is Mesozoic epigenetic hydrothermal metallization in the intracontinental subduction orogenic system, showing the characteristics of ore control of basin borderlands, stratabound mineralization within dynamic transitional belts, pair paragenesis of epithermal mineralization and mesogene in collision orogenic system.
