Study area is located in the eastern Tianshan orogenic belt, involving Tianshanand North Tianshan two major tectonic units, take the Aqqikkudug fault zone fromeast to west as the boundary, the south side of the middle Tianshan block is anintegral part of the Tarim plate. Since the early Proterozoic separated from the Tarimplate,the south side of the middle Tianshan block has experienced cracking on and offmagmatic events from southern part of South Tianshan Ocean and the northern part ofthe Paleo-Asian ocean, there has the role of multi-cycle magma, intrusive rocks havea wide distribution area, Become a major component of the middle Tianshan crust.The north side of the North Tianshan tectonic unit is the product of the Paleo-AsianOcean tectonic domain. Multi-phase, multi-cycle made study area was accompaniedby crustal accretion and a lot of copper, gold, iron, lead, zinc, silver and copper-nickelsulfide and other polymetallic mineralization in each stage of tectonic evolution.In this paper,based on geologic, geophysical, geochemistry and remote sensingdata, etc. using the Plate tectonics and activities as the basic theory andmethod.Through the understanding about the study area’s structural characteristics,tectonic evolution and the geological background, determine the study area is acontinuous gradual plate with open, integration and orogenic processes in LatePaleozoic of the tectonic evolution.It can be divided into the formation of Tupan-hamiocean in Devonian,subduction-type orogeny in early Carboniferous, collisionalorogeny in late Carboniferous and post orogenic further deformation of the platesuture in Permian. After orogenic suture zone the collision, nappe and the formationof four stages in Permian.Finally, using the theory of tectonic and metallogenic seriesto summary the law of mineralization of the main mineral in the region, establishmentof the main mine area. To provide a basis for further mine exploration, and it has animportant significance.
