摘    要:以南秦岭及邻区为例, 从大陆岩石圈地幔尺度上探讨了早古生代以来4 种大陆动力学成矿系统及其14 种不同的成矿系列, 并指出了具有重要经济价值的主要成矿系列及今后的找矿方向。在早古生代大陆岩石圈地幔垂向构造扩展动力成矿系统中, 陆缘主动裂谷盆地中, 陆缘主动裂谷盆地中Ni-V-Mo-Au-U-Se等是主要成矿系列。晚古生代岩石圈地幔俯冲收缩导生大陆壳伸展形成的伸展动力学成矿系统中, 形成的4种成矿系列是具有重大经济价值的主要成矿系列。印支期陆陆碰撞造山期形成的含金剪切型金成矿系列及燕山期- 喜马拉雅期陆内造山期热泉型金矿成矿系列中, 常形成大型-超大型金矿矿集区。

关 键 词:秦岭造山带  南秦岭及邻区  大陆动力成矿系统  成矿系列  超大型矿床  找矿方向

Abstract:The metallogenic system of continental dynamics and the metallogenic series related to the continental lithosphere are the important topic in the study and ore deposits Metallogenic systems, often with a certain geological realm in the continental lithosphere,are the natural system with ore forming function and consist of different kinds of metallogenic series formed in different geological environments by different ways of ore formation at the same time series From the scale of the lithosphere since the lower Paleozoic in the area, four kinds of metallogenic systems of the continental dynamics, three metallogenic series and twenty three geochemical patters of ore deposits associtaion have been discussed in his paper,and major meallogenic series with significant value and prospecting orientation have also been discussed in the paper The major metallogenic series in the metallogenic system of the extension dynamics in the continental crust formed by vertical tectonic spreading of mantle plume is the metallogenic series of Ni V Mo Au U Se Pt in the lower Paleozoic active rifted basin Four types of metallogenic seris with a significant economic value were formed in the upper Paleozoic extensional metallogenic system at the processes of the extension of the continental crust in the area which were produced by north directed slow convergence of the deep mantle Often with large to superlarge Au mineralized areas, gold bearing shear zones were formed in the processes of continent to continent collision in the Qinling at the Indio Chinese orogenic movement and Au metallogenic series of hot spring occurred from the Yanshian movement to the Himalaya movement in the processes of intracontinent tectonism
Keywords:Qinling orogen  South Qingling metallogenic system of continental dynamics   Metallogenic series   Superlarge ore deposits   Prospecting orientation
