Mafic-ultramafic intrusion is a main vector of magmatic sulfide (Ni-Cu-PGE) deposits and oxide(Fe-Ti-V-P) deposits in the world. The world’s major magmatic sulfide deposits and magmatic oxide deposits can occur in large igneous provinces, cratonic rift zone areas or extension setting,stretching post-collisional environment of the folded belt. Comparative analysis shows that the mineralizing process is complex,and it may not be preferable that trying to use a model to interpret the process of all the similar deposits.There is no doubt that an appropriate redox environment is the necessary conditions for the formation of magmatic deposits.Accompanied by crystallization of magma and mineralizing process of change in oxygen fugacity and incentive problems remain to be explored further.
