The Structure Evolvement of Easten Tianshan Mts Orogenic Zone in Late Paleozoic And Polymetal Mineral Resources Metallogenic Regularity

The eastern Tianshan Mts orogenic zone during the late Paleozoic underwent four stages geolog-ical evolution including the formation of Tupan-hami ocean in Devonian,subduction-type orogeny in early Carboniferous,collisional orogeny in late Carboniferous and post orogenic further deformation of the plate suture in Permian.Three obvious tectonic belts of the eastern Tianshan Mts orogenic zone,represented by Dananhu-haelike island arc zone,Kang-a plate suture zone,Middle Tianshan Mts island arc zone.,can be subdivided from north to south.Distribution of Ore deposits in the eastern Tianshan Mts is remarkably controlled by tectonics,and the copper,gold and magmatic Cu(Ni) sulfide metallogenic deposits of late Pa-leozoic display obvious temporal-spatial evolution regularity.They are porphyry copper deposits,magmatic Cu(Ni) sulfide deposits and ductile shear zone type gold deposits,skarn-type copper-ploymetallic deposits and hydrothermal gold deposits.The above different type deposits spatially formed four large metallogenic belts: Copper metallogenic belt to the north of Kangur fault;Gold,copper and nickel metallogenic belt(North Belt);Iron,copper,and silver polymetellic metallogenic belt of Yamansu-Aqqikkudug area(South Belt);Iron,lead-zinc and silver metallogenic belt.
