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。

Abstract: | 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 1 989 to 2014,the scale of Poyi Cu-Ni deposit in Pobei rock belt is up to above 1 million 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 mine-ralization,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. |
