    新疆巴里坤县八墙子一带金、铜成矿规律分析及找矿方向

    Metallogenic Geological Conditions and Prospecting Model of the Hulunxibai Gold Deposit in Ejinaqi, Inner Mongolia

    • 摘要: 研究区位于准噶尔成矿省巴尔鲁克山—三塘湖晚古生代、中生代Cu、Au成矿带东段,构造上属唐巴勒-卡拉麦里古生代复合沟弧带。出露地层主要为奥陶系中酸性火山岩、火山碎屑岩及正常碎屑岩组合,泥盆系陆源碎屑岩、火山岩及火山碎屑岩组合,及石炭系正常碎屑岩夹火山碎屑岩组合。研究区侵入岩主要形成于华力西晚期,表现为从基性到酸性演化的特征。区内断裂和褶皱构造发育,为成矿提供了空间。笔者主要是通过对巴里坤县八墙子一带Au、Cu等元素在各个地层单元、侵入岩及构造中的分布特征研究,结合区内已发现的金、铜矿床、矿(化)点及异常的分布特征,总结了研究区金、铜矿成矿规律及找矿方向,认为区内金、铜矿产的形成与大地构造环境、区域构造以及岩浆活动有直接的关系。

       

      Abstract: Study area is located in Jungger metallogenesis province,eastern of Baerluke-santanghu Paleozoic and Mesozoic CU,Au metallogesis belt.Tectonic belongs to Tangbale-Kalamaili Paleozoic fossa-arc belt.The stratum is mainly the combination of Ordovician intermediate-basic volcanic rocks,Volcanic clastic rocks,and normal elastic rocks.The Devonian is the combination of terrigenous deposit roeks,lava,and volcanic elastic rocks.While the Carboniferous is the normal elastic rocks and volcanic elastic rocks.The intrusive rock in the study area was mainly formed in late Variscan,having a characteristic from basic to acid.The faults and folds are well developed,providing the space for deposits.Based on the distribution characteristic of Au-Cu minerals in various stratum units,we summarize the metallogenic law of Au-Cu mineral deposits,showing that the formation of Au-Cu mineral deposit is directly related to tectonics,regional structures,and magmatic activities.
