| Abstract: | The mode of occurrence,development,classification,metallogenic features,and cyclicity of the ore\|forming system of plume tectonics are preliminarily discussed from the angles of plate tectonics and mineral deposits associated with plate boundaries,supercontinental cycles and mineral deposits associated with continental boundaries,mantle hot spots and intracontinental mineral deposits,and crust\|mantle metallogenic systems.It is considered that the ore\|forming system of plume tectonics includes two ore\|forming subsystems of hot and cold plumes,which, in turn,consist of five further subdivided ore\|forming systems called mantle hot plume\|hot spot subsystem,mantle hot plume\|continental rift subsystem,mantle hot plume\|ocean floor spreading subsystem,mantle cold plume\|Precambrian ensialic orogenic sybsystem and ensialic/ensimatic orogenic sybsystem respectively.Metallogenic series produced by the ore\|forming subsystems are preliminarily divided,and some mineral deposits are illustrated.The ore\|forming system of plume tectonics refers to the whole ore\|forming process of plume tectonics together with its products.The ore\|forming subsystem of mantle hot plume\|hot spot,as the starting point of the time\|space evolution of the ore\|forming system of mantle hot plume,frequently develops into the ore\|forming subsystem of mantle hot plume\|continental rift,mainly giving birth to the ore\|forming system of plume tectonics.The ore\|forming subsystem of mantle hot plume\|ocean floor spreading is a product of the ore\|forming subsystem during the late evolution stage of the ore\|forming system of plume tectonics. |
