The Neoproterozoic mantle plume had possibly triggered the breakup of the Rodinia supercontinent and large scale basaltic magmatisms,which occurred in Tarim,South China Craton and Australia.The age of Jinchuan ultramafic intrusion (Zhang et al.,2010;Li et al.,2005) makes Rodinia breakup magmatisms important because of the largest single magmatic Ni-Cu sulfide deposit in the world.In this paper,we use zircon U-Pb dating and Hf isotopes to outline the range of Neoproterozoic mantle plume magmatism possibly related to Ni-Cu sulfide mineralization during the breakup of the Rodinia supercontinent in the Qilian orogenic belt (QOB),Tarim and North and South China Craton (NCC,SCC).
