Crust accretion and mineralization is the research on the frontier of economic geology. The eastern Tianshan orogenic belt is key part of the central Asia orogenic belt，its late paleozoic crust evolution has experienced subauction accretion，collision and large scale strikeslip，different stage has occurred many metal deposits. Copper(nickel)deposits in the eastern Tianshan have been assigned to four major types according to the tectonic setting in which they formed. These are： 1)preaccretionary late Devonianearly Carboniferous porphyrytype CuMoAuAg deposits； 2)early Carboniferou preaccretionary VMS FeCuPbZn massive sulfide deposits， 3)synto postaccretionary Late CarboniferousEarly Permian magmatic CuNisulfide deposits； and 4)postaccretionary Late CarboniferousEarly Permian orogenic AuCu deposits. The geodynamics processes of these deposits is related to the crust horizontal and vertical accretions. The eastern Tianshan domain has been the one of the most important metal deposits provinces in China.
