摘要: 摆浪沟地区地处北祁连山西段奥陶纪弧后盆地火山岩带内,区内古火山机构保留完整,火山岩系为蛇绿岩套上部火山岩的组成部分,岩相发育齐全,与铜矿化密切相关的热水沉积岩——红碧玉岩发育,沿火山机构铜矿化发育普遍,既有与构造破碎带有关的铜矿化,也有与喷流岩有关的火山块状硫化物矿化存在,显示了该区寻找富铜块状硫化物矿床的巨大前景。Abstract: Bailanggou mineralized region is located in the Ordovician back-arc basin volcanic rock belt along the west sectoin of North Qilian Mountains.The pelovolcanic edifice is storaged effectely.The volcanic rock belongs to the upper part of the opholite suite, the volcanic lithofacies developed entirely and the exhalite related copper mineralitation-red jasper is developed abroadly.The copper mineralitation is found in the pelovolcanic edifice every where.They are divided into two kinds, one is related with tectonic crushing belt, the other is the volicanic massive sulfide metallization related with submarine hydrothermal-solution spouting.It shows that there is quite large potential capacity of prospecting rich-copper volicanic massive sulfide deposits in the region.
