摘    要:本文通过对江西金山剪切带型金矿床中含金石英脉的地质和流体包裹体类型、成分和稳定同位素组成等特征的研究。认为金山剪切带型金矿床含金石英脉是由早期产生的不含金石英脉在遭受碎裂和靡棱岩化时被晚期自然金矿化叠加而形成,自然金矿化的叠加是通过地下热水作用而实现的,而引起自然金沉淀的因素主要是流体的相分离。

关 键 词:金矿床 含金 石英脉 成矿特征

Abstract:Studies of the geology, types and composition of fluid inclusions and stable iso-topic composition show that auriferous quartz veins in the Jinshan shear zone type deposit, Jiangxi Province, was formed by mineralization and superimposition of early-formed barren quartz veins by late-stage native gold when the former were subjected to cataclasis and mylonitization. Native gold superimposition occurred by means of the action of subsurface hydrothermal waters; therefore the factor responsible for the deposition of native gold was mainly the phase separation of ore fluids.
Keywords:gold deposit   shear zone type   auriferous quartz vein   metallogenetic characteristic   Jinshan   Jiangxi Province
