摘要
新疆北山坡北基性-超基性杂岩体逆向同源成分演化特征明显、结构演化不清楚,包括角闪辉长岩、辉长苏长岩、橄榄辉长岩、橄榄辉石岩和辉石橄榄岩、斜长(拉长)岩5个岩相单元。钛铁矿化与角闪辉长岩相有关,铜镍矿化与橄榄辉长岩相和橄榄辉石岩及辉石橄榄岩相有关。综合研究认为,新疆北山构造带西段坡北杂岩具有较好的铜镍矿及钛铁矿成矿和找矿前景。
The backward cognate composition evolution of the Pobei mafic-ultramafic complex is appreciable and the structural evolution is unappreciable, including 5 lithofacies units, that is, hornblende gabbros, gabbro-norite, olive gabbro, olivine pyroxenite and pyroxene peridotite, early and late anorthosite. Ti-Fe mineralization is concerned with hornblende gabbro lithofacies which is the first element. Cu-Ni mineralization is concerned with olive gabbro, olivine pyroxenite and pyroxene peridotite lithofacies. This shows that there is a good metallogenic and exploration prospect of Cu-Ni deposits and Ti-Fe deposits in the Pobei complex of the Xinjiang Beishan structural zone.
