| 摘 要： | 经研究确认,内蒙古查干哈达庙铜矿床属于块状硫化物型富铜矿床。该矿床类型的首次确认,为华北陆块北缘寻找古生代块状硫化物型富铜矿床提供了例证。查干哈达庙铜矿床位于华北陆块北缘,赋矿地层（即含矿岩系）为石炭系上统本巴图组流纹质凝灰岩、凝灰质板岩,其上为条带状结晶灰岩、生物碎屑结晶灰岩。含矿岩系中存在硅质岩、含铁硅质岩、碧玉岩及萤石重晶石矿层。硫化物矿体呈层状、似层状,产于流纹质凝灰岩、凝灰质板岩岩层中,产状与岩层产状一致。矿床含矿岩系具有＂火山碎屑岩、硫化物矿体、碧玉岩＂的＂三位一体＂特征。矿石具有条带状、层纹状构造。矿石中主成矿元素为Cu,伴生有益元素为Au,S,Pb,Zn,铜矿石品位较高,属富铜矿。矿床地质特征表明其属块状硫化物型铜矿床。该类型矿床的找矿标志是,在海相酸性火山岩及碳酸盐岩之间,地表存在与硅质岩共存的黄钾铁矾、铁帽型硫化物氧化带;具有以铜为主的铜、锌组合的化探异常;具有低阻高极化的物探异常。 |

| Abstract: | The Chaganhadamiao ore deposit in Damao County,Inner Mongolia is a newly discovered rich copper deposit and firstly identified as VMS ore deposit and will provide important clues to Paleozoic VMS rich copper deposits in the northern margin of the North China Craton.The ore is hosted by rhyolitic tuff and tuffaceous slate of the Benbatu formation of Upper Series of Carboniferous System that is overlain by striped crystalline limestone and bioclastic crystalline limestone.Layers of siliceous rock,ferrous cher... |
| Keywords: | Chaganhadamiao Cu deposit VMS deposit geological feature northern margin of the North China Craton Inner Mongolia |
