Nanhua system are widely distributed in the Kuluketage, Xinjiang. There are three glacier activities in Nanhua system. The authors suggest that episodes of mantleplume activities between 830 Ma and 630 Ma during the break-up of supercontinent Rodinia within in the Kuluketage. The Qieganbulake apatite-vermiculite deposit and the Xingdi ⅡCu-Ni deposit formed in a Neoproterozoic continental rift setting, possibly related to mantle plume activities that led to the breakup of the Rodinia supercontinent. Kuluketage belt that was likely derived from northern Yangtze craton. The Qieganbulake and Xingdi Cu-Ni sulfide-bearing intrusions, along with coeval regional plumerelated mafic dykes, are interpreted to be genetically related to the same period south China mantle plume rocks.
