【摘要】 目的探讨中秦岭地区铅锌金多金属矿集区的成矿地质背景和成矿机制。方法从板块构造角度进行分析。结果位于商丹带与留坝—山阳断裂带之间的中秦岭地区,其主体是在华北南缘晚古生代活动陆缘环境下增生的一个介于秦岭古岛弧带和留坝—山阳古俯冲带(古海沟)之间,并建立在俯冲增生楔之上的弧前盆地,发育有大规模的热水成矿系统。结论该区是横亘中国大陆中部的中秦岭岷礼—西成—凤太—山柞大型—超大型金、铅锌多金属矿集区。更多还原

【Abstract】 Aim To analyze the geology backeround and metallogenetic mechanism of Pb-Zn-Au polymetallic oreconcentration area in the middle part of Qinling area.Methods Make discussions from the view of plate tectonics.Results The middle part of Qinling area is between Shangdan zone and Liuba-Shanyang fault zone,the main part of which is a forearc basin based on accretionary prism between the Qinling paleo-arc and Liuba-Shanyang plaeo subduction zone(ancient trench) in the Late Paleozoic active margin environment.There are lots of hydrothermal metallogenetic system.Conclusion It formed the Minli-Xicheng-Fengtai-Shanzha(super)large scale Pb-Zn-Au polymetallic ore concentration area which is located in the central part of China continent.更多还原
