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。 The research confirmed that the Chaganhadamiao copper deposit in Inner Mongolia belongs to the massive sulfide-type copper-rich deposit. The first confirmation of the type of deposit provided an illustration for the search for Paleozoic massive sulphide type copper-rich ore deposits in the northern margin of the North China block. The Chaganhadamiao copper deposit is located on the northern margin of the North China terrane, and the ore-bearing strata (ie, the ore-bearing strata) are rhyolite tuffs and tuffaceous slate of the Upper Bantu Formation in the Carboniferous. Limestone, biological clastic crystalline limestone. In the ore-bearing rocks there are chert, siliceous rocks, jasperite and fluorite barite. Sulfide orebodies are layered and layer-like, and are produced in rhyolitic tuff and tuffaceous slate strata, and their occurrences are consistent with those of rock strata. The ore-bearing strata in the ore deposit have the characteristics of “trinity” of “pyroclastic rocks, sulphide ore bodies and jasper rocks”. Ore has a banded, layered structure. Ore ore in the main elements of Cu, associated beneficial elements of Au, S, Pb, Zn, copper ore grade is higher, is a copper-rich ore. The geological characteristics of the deposit indicate that it is a massive sulphide type copper deposit. The ore-prospecting sign of this type of deposit is that between the marine acid volcanic rocks and carbonate rocks, there exists jarosite and iron-cap sulfide oxidation zone coexisting with the chert on the surface of the earth; copper , Geochemical anomaly of zinc combination; with low resistance and polarization of the geophysical anomalies.
