| 摘 要： | 根据构造单元、构造演化及其矿床组合,将秦岭造山带划分为4个成矿集中区:小秦岭古陆活化区、熊耳山裂谷增生区、南秦岭被动陆缘断陷区和碧口地体古拼合带。分别构成4个成矿系列:花岗-绿岩带型金-铁矿床系列、陆相火山岩型金-钼矿床系列、沉积岩型金-铅锌-汞锑矿床系列、海相火山岩型金-银-多金属矿床系列与超基性岩型镍-金矿床系列。矿床系列表现出同生成矿作用和后生叠加改造成矿作用的演化,同生成矿作用与造山带形成早期(古生代及其以前)广泛的地幔羽或热点活动有关,后生成矿作用是在盆山转化和陆内构造-岩浆活动时期(120～340Ma)完成的。

| Abstract: | On the basis of the tectonic units,tectonic evolution and deposit association,the Qinling oro-genic belt is divided into four mineralization concentration areas:the Xiao Qinling craton activation area,Xiong'ershan rift accretion area,South Qinling passive continental-margin down-faulted area and Bikou terrane paleo-assemblage zone,which separately form four minerogenetic series:the granite-greenstone belt-type gold-iron minerogenetic series,continental volcanic-hosted gold-molybdenum minerogenetic se-ries,sedimentary-hosted gold-lead-zinc-mercury-antimony minerogenetic series and marine volcanic-host-ed gold-silver polymetallic and ultrabasic-hosted nickel-gold minerogenetic series.Syngenetic mineralization is related to extensive mantle or hot spot activities in the early stage(Paleozoic and its preceding stage)of format of the orogenic belt;post-genetic mineralization was accomplished during the basin-range transfor-mation and intracontinental tectono-magmatic activities(at120-340Ma ). |
