摘　　要：内蒙古黑鹰山地区黄羊坡南地处北山成矿带西段黑鹰山成矿亚带,成矿地质条件优越。研究表明:该区处于Ni、Cu、Fe、S地球化学高背景区,主要产出铁族和亲硫元素两类地球化学异常,铁族元素异常与北西向辉绿岩脉密切相关,亲硫元素异常多与红柳园组火山岩及花岗斑岩脉相关;激电测量低阻高极化异常沿北西向呈带状分布,存在多个高视充电率和低视电阻率组合异常,推断深部-300米以浅可能存在向南西倾的多金属硫化物矿化体,辉绿岩脉两侧为有利找矿部位;辉绿岩中金属矿物组成与典型铜镍硫化物矿床相似,综合推断该区深部具有形成铜镍硫化物矿床的潜力,具有良好的找矿前景。The south of huangyangpo in Heiyingshan area,Inner Mongolia,is located in the west part of the Beishan metallogenic belt,and the metallogenic geological conditions are superior.The results show that the area is located in the high geochemical background of Ni,Cu,Fe and s,and there are mainly two kinds of geochemical anomalies of iron group and sulfur-loving elements.The anomalies of iron group elements are closely related to the NW diabase vein,most of which are related to the volcanic rocks and granite porphyry vein of hongliuyuan formation.The low resistivity and high polarization anomalies of IP measurement are distributed in a belt along the NW direction,and there are many high apparent charge rates It is inferred that there may be a polymetallic sulfide mineralized body inclined to the south-west in the depth of-300m and the two sides of diabase vein are favorable for prospecting.The composition of metal minerals in diabase is similar to that of typical copper nickel sulfide deposits.It is concluded that the deep part of the area has the potential to form copper nickel sulfide deposits and has a good prospecting prospect.
