摘　　要：内蒙古东乌珠穆沁旗呼和阿腊格地区大地构造位于内蒙—兴安造山带,二连—贺根山蛇绿混杂岩带内。为内蒙地区蛇绿岩带的北带。该带内是Fe、Cu、Ni、Pt、Ti富集区。呼和阿腊格地区已发现的铜镍矿体属于超基性岩型低品位铜镍矿床,含矿围岩主要为中晚泥盆世蛇纹岩、斜辉辉橄岩、深部钻孔验证为蛇纹岩、辉长岩、绿泥蚀变岩,且岩石普遍具弱磁性,从地球化学特征分析,该矿超基性岩体内部Ni元素富集,同时伴生Co元素,局部Cu矿富集。The geotectonics of Huhe Arage area in East Wuzhumuqin Banner, Inner Mongolia is located in the Inner Mongolia Xing’an orogenic belt and Erlian Hegenshan ophiolite melange belt. It is the northern belt of the ophiolite belt in Inner Mongolia. The zone is rich in Fe, Cu, Ni, Pt and Ti. The copper nickel ore body discovered in Hohhot Arage area belongs to ultrabasic rock type low-grade copper nickel deposit. The ore bearing wall rocks are mainly Middle Late Devonian serpentine, clinopyroxenite, and the deep boreholes are verified to be serpentine, gabbro, and chlorite altered rocks, and the rocks are generally weakly magnetic. According to the analysis of the geochemical characteristics, the ultrabasic rock body of the mine is rich in Ni elements, accompanied by Co elements, and locally rich in Cu ore.
