摘　　要：新疆北山裂谷带中出露有数量众多的镁铁-超镁铁岩,坡一铜镍矿位于北山裂谷金铜镍成矿带西部、坡北镁铁-超镁铁岩带西南部。经1989~2014年的持续勘查,坡北岩带中的坡一铜镍矿规模达到100万吨以上。笔者在前人工作的基础上,结合裂谷环境下成岩机制,分析了坡一铜镍矿成矿环境及成矿作用演化特征,树立了独特的多期岩浆成矿模式,建立了找矿标志,为成矿带镁铁-超镁铁岩浆硫化物型铜镍矿床建立了成矿模型,且对成矿远景做了探讨。A large number of outcropped mafic-ultramafic rocks exist in Beishan rift valley zone of Xinjiang,and Poyi Cu-Ni deposit is located at the western part of Beishan rift valley Au-Cu-Ni metallogenic belt and the southwestern part of Pobei mafic-ultramafic rock belt.According to the ongoing exploration in this area from 1989 to 2014,the scale of Poyi Cu-Ni deposit in Pobei rock belt is up to above 1million tons.Based on previous works of predecessors,and combined with the diagenetic model in the environment of rift valley,this paper analyzed the mineralization environment of Poyi Cu-Ni deposit and evolution characteristics of mineralization,and it also set up a unique multi-phase magmatic mineralization model and summarized some clues for prospecting.The author established a metallogenic model for mafic-ultramafic magma sulfide type Cu-Ni deposit in the metallogenic belt,and put forward the prospecting prospect.
