摘　　要：喀腊奥依金铜矿位于准噶尔东北缘浅覆盖区,为浅覆盖区找矿勘查工作的新突破。在研究浅覆盖层厚度、地球物理、浅钻化探特征基础上,通过钻探验证,查明控矿要素,认为该矿具斑岩型金铜矿特征。赋矿岩石为泥盆纪石英闪长岩、花岗闪长岩,含矿岩石微裂隙发育;具弱正磁异常、中等电阻率、中高极化率物探特征;浅钻化探成果显示具Au,Cu,Mo,Ag,Sb,As等元素综合异常。该矿床的发现作为浅覆盖区勘查示范案例,建立了浅覆盖区斑岩型金铜矿找矿标志,为浅覆盖区找矿勘查方法技术组合研究奠定了基础。The Kalaaoyi gold copper deposit is located in the shallow coverage area of the northeastern margin of Junggar.It is a new breakthrough in the exploration of shallow coverage areas.Based on the study of the thickness,geophysics,and shallow drilling geochemical characteristics of the shallow coverage layer in the mining area,the controlling elements were identified through drilling verification,and it is believed that the deposit has typical characteristics of porphyry gold copper deposits.The ore bearing rocks are Devonian quartz diorite and granite diorite,with developed microcracks in the ore bearing rocks.The mining area has weak positive magnetic anomaly characteristics,medium resistivity,and medium high polarization induced polarization characteristics.Shallow drilling geochemical exploration shows comprehensive geochemical anomalies of elements such as Au,Cu,Mo,Ag,Sb,and As in the rocks.However,the shallow cover layer has a certain impact on the results of induced polarization methods.The discovery of this deposit serves as a demonstration case for shallow cover area exploration,establishing indicators for the exploration of porphyry type gold and copper deposits in shallow cover areas and laying the foundation for the research on the combination of exploration methods and technologies in shallow cover areas.
