青海铜峪沟铜矿床的矿化特征、形成环境和矿床类型

Mineralized feature, tectonic setting and metallogenic type of Tongyugou cupper deposit, Qinghai province

  • 摘要: 铜峪沟矿床位于青海省海南三叠纪沉积盆地中一条近东西向滑塌堆积带内,赋存于正常沉积岩系与火山沉积岩系过渡部位,以典型层状矿体并与层矽卡岩和富硅质沉积物相伴生为突出特征。依据含矿岩系的沉积建造、沉积相和火山岩性质等多种方法判别该矿床形成于陆缘拉张裂陷盆地环境,对比表明矿床介于Sedex型和陆壳背景下的Besshi型之间而更接近后者。
    Abstract: Tongyugou cupper deposit located at the Triassic sedimentary basin of Hainai (to the South of Qinghai Lake) occures in a olistostrome felt with E-W orientation and in the transitional position from marene sedimentary series to volcanic-sedimentary series, which is characterized by typical dedded or ebodies and association with wrigglites and silicon-rich sedimentary rocks.On the basis of the sedimentary formation, sedimentary facies of ore-bearing series and the nature of the volcanic rocks, the tectonic setting of the deposit is considered to be spreading-subsidence basin existting in continental margin.The contrast to different stratiform sulfide deposits indicate Tongyugou depositis between Sedex type and Besshi type but closer to the latter.
