There are four deposit types related to a Permian mafic complex in northern Xinjiang,i.e., copper-nickel sulfide deposit,vanadic titanomagnetite deposit,magnetite(-cobalt)deposit and Cu-Ni- VTiFe composite deposit.The deposits are distributed spanning tectonic units with close and consecutive metallogenic ages.A transitional deposit type can occur among the end-member deposits. Trace elements of host rocks show that they can derive from similar source area.Hence,they constitute a particular metallogenic series related to a mafic-ultramafic complex that is also a symbol series of the post-collisional stage of the Central Asia Metallogenic Province(CAMP).The metaliogenic ages of the series are between 260 Ma and 300 Ma throughout the Permian.Unlike mineralization from a mantle plume,the metallogenic period of this series spans at least 40 Ma. Compared with related deposits of the Emeishan mantle plume,the North Xinjiang series has a similar ore-forming element assemblage but has preferably developed Cu-Ni sulfide deposits rather than vanadic titanomagnetite deposits.In concomitance with this series,North Xinjiang area has developed a set of syntectonic Au-Cu-Mo metallogenic series related to a felsic volcanic-intrusive complex,which might indicate that there is no direct relationship with mantle plume activity.From early to late,i.e.,the sequence of copper-nickel sulfde to magnetite(-cobalt)to vanadic titanomagnetite deposit,the host rock series evolves from mafic-ultramafic and tholeilte series to marc and alkalic series,the∑REE content tends to increase with increasing of REE fractionation,and some of the trace elements(particularly LIL)also show an increasing tendency.The above evolutionary regularity possibly reflects a course where the magma source deepens and thermal interface moves down,energy gradually exhausts,and neo-continental crust forming in the post- collision stage tends to stabilize.
