摘要
寨上金矿床产于南秦岭古生代裂陷海槽局限盆地上泥盆统含C、Ca质复理石建造中,矿床规模较大,品位低,成矿元素复杂;受特定岩相沉积环境的含矿地层和后期陆内造山脆 韧性叠加断裂及伴随的成矿流体的联合控制;是西秦岭近2年新发现的较典型的沉积岩容矿的卡林型金矿床;由含As黄铁矿、含As黄铁矿 毒砂、铜 金与锑 金矿石组成;含Au黄铁矿、毒砂具有特征的增生环带结构;矿化带、矿体成矿元素具有Au As Sb Hg Cu Pb Zn Ba组合特点。
The Zhaishang gold deposit occurs in local basin of South Qinling Paleozoic era fault,and is composed in carbonaceouscalareousbearing flysch formation of Upper Devonian series.The gold deposit has largescale,lower ore grade and complicated oreforming elements.Zhaishang gold deposit is controlled by the orebearing bed of sedimentary environment of specific lithofacies and stacked brittleductile fracture of continental orogenic belt and its associated mineralization liquor at South Qinling in later stage.It is a typical Carlin type gold deposit that is discovered in recent years at West Qinling.The ores are composed of the pyrite,arsenobearing pyrite,arsenopyrite and stibium et al.The metallogenic elements form association of AuAsSbHgCuPbZnBa in these orebodies and mineralized belts.
