岩浆铜镍硫化物矿床主要赋存在镁铁-超镁铁质岩体中，赋矿岩体规模一般较小，矿体主要赋存在岩体的下盘，形成了很多小岩体大矿床的现象。世界上镁铁-超镁铁质岩体很多，如何判定岩体深部是否具有成矿潜力一直是大家关注的焦点。本文在前人大量研究的基础上，以东天山地区为例，对比剖析了成矿与不成矿镁铁-超镁铁质岩体的地质、地球化学特征，试图从理论上判别岩体的成矿潜力。提出成矿的超镁铁质岩体一般具有明显右倾的稀土配分曲线，岩体属于多期岩浆侵入形成，岩石中含一定量的斜方辉石，造岩矿物颗粒大小具有明显变化等找矿评价指标

The magmatic Cu-Ni sulfide deposit is mainly hosted in mafic-ultramafic intrusions which are generally small scales. The ore body is mainly hosted in the base of the intrusion. This forms a large number of deposits which we call “mall intrusion forming large deposit”. In the world，there are many mafic-ultramafic intrusions，but how to determine the metallogenic potential of intrusion has been concerned all the time. In this paper，based on previous studies，we take eastern Tianshan as an example，compare and analyze the geological and geochemical characteristics of the economic mineralized mafic-ultramafic intrusions and the uneconomic mineralized mafic-ultramafic intrusions，in order to distinguish the metallogenic potential from theory. The prospecting evaluation indexes are gained from this study，mineralized mafic-ultramafic intrusions are generally characteristic by right incline in Chondrite normalized REE pattern diagrams；several stages of magma intruding are important；a certain amount of orthopyroxene is contained in the rock；the mineral grains are obviously different， et al.
