Abstract：Kuluketage block is one of the best areas for Precambrian geology studies in Xinjiang,however,the regional metal-logeny of the research area is still too poon.In this paper,all the published literatures are summarized.Then,the geology of main ore deposits and the classified metallogenic series in this block are systematically described.The following seven tectono-thermal periods are distinguished:Archean crust nucleus growing stage (3.3 -3.0 Ga),Neoarchean-Paleoproterozoic crust growth and transformation stage (2.6-2.3 Ga),middle-late Paleoproterozoic crust transformation stage (2.1-1.8 Ga),Late Mesoproterozoic to Early Neoproterozoic orogeny stage (1.1 -0.86 Ga),Middle Neoproterozoic orogenic extensional stage (830-800 Ma),middle-late Neoproterozoic intracontinental breakup stage (770-630 Ma)and Early Paleozoic land building stage.Mineralization mainly occurred at Paleoproterozoic,Neoproterozoic and Early Paleozoic.According to the ore-formingtectonic settings,ore-bearing rock formations and ore deposit genesis,six typical metallogenic series are identified in our study, including Fe-P-Cu-Au metallogenic series formed at Paleoproterozoic crust growth and transformation stage,Cu-Au metallogen-ic series formed at Early Neoproterozoic orogeny stage,Cu-Mo-Au-Fe-P-REE metallogenic series formed at Neoproterozoic post-collision stage,Cu-Ni metallogenic series formed at Neoproterozic rifting stage,Ag-V-Mo-Au-U-P metallogenic series formed at Early Paleozoic sedimentary basin and Cu-Au metallogenic series formed at Early Paleozoic arc subduction stage.
