摘　　要：对新疆西昆仑岔路口地区马鞍山岩体进行主量元素、微量元素研究,马鞍山基性-超基性岩是由二辉橄榄岩、单辉橄榄岩、辉石岩、辉长岩和闪长岩组成的一个杂岩体,岩体受控于乔尔天山-岔路口深大断裂。通过与新疆黄山岩体对比发现,其岩石学、岩石地球化学特征相似,且发育硫化物型黄铜矿-镍黄铁矿-磁黄铁矿组合。综合已有地质、物探、矿产成果,认为马鞍山超基性岩具岩浆熔离型铜镍矿含矿岩体基本特征,为新的铜镍找矿潜力区。The main elements and trace elements of Ma'anshan rock mass in Chalukou area of Western Kunlun in Xinji-ang are studied.Ma'anshan basic-ultrabasic rock is a complex rock mass composed of lherzolite,lherzolite,pyroxenite,gabbro and diorite.The rock mass is controlled by the Qiaoer Tianshan-Chalukou deep fault.By comparing with the Huangshan rock mass in Xinjiang,it is found that its petrological and geochemical characteristics are similar,and the sulfide type chalcopyrite-nickel pyrite-pyrrhotite combination is developed.Based on the existing geological,geophysical and mineral achievements,it is considered that the Ma'anshan ultrabasic rock has the basic characteristics of magmatic liquation type copper-nickel ore-bearing rock mass,which is a new copper-nickel prospecting potential area.
