秦岭金属矿床成矿系列与大陆造山带构造动力学背景

摘要:
提要: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:
Abstract: On the basis of the tectonic units, tectonic evolution and deposit association, the Qinling orogenic 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 series, sedimentary-hosted gold-lead-zinc-mercury -antimony minerogenetic series and marine volcanic-hosted 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 transformation and intracontinental tectono-magmatic activities (at 120 -340mA).
