nt of backarc rift of the Late Paleozoic (ie Chur, oytag, Liang rift trough). With the demise of the PaleoTethys, Kusi La Fu Long Late Paleozoic rift basin closed at the end of the Permian. Triassic in this area in the uplift and denudation, missing deposition. Jurassic mountain basin phase sandwiched between swamp facies. To the end of the Cretaceous and early Tertiary early, due to the role of NeoTethys rift suffered a transgression, forming a shallow marine to lacustrine sedimentary rocks. Himalayan orogeny, the NeoTethys closed, the rise of the Tibetan Plateau, the basin tectonic sharp distinction, causing largescale overthrusting and strikeslip of the the West Kunlun front of this area, the formation of iron in grams over the nappe and other structures, tectonic framework laid today. The So, Kusi La Fu Long leadzinc (copper) with which the tectonic position for the Late Paleozoicarc rift basins))) with the base of the continental crust oytag Chur Liang rift trough Late Paleozoic rift sedimentation, late Hercynian the Hi malayan period of strong tectonism of the area a wide range of highintensity lead and zinc (copper) to create 5 a favorable structural conditions [5]. Tamu Tamu MVT PbZn and peripheral of the Upper Devonian, Carboniferous, Jurassic and Cretaceous) Tertiary strata, fold structure is the Cork contingent Daban plex syncline, East Wing, syncline regional faults in Kyzyl Tao the Kusi La just northnorthwest trending strikeslip fault system and the North West to Kun North inverse nappe fault system. Tectonic Line in the region overall NWtrending fault structure is developed, strongly deformed, often developed along the fault structure with dynamic metamorphism and tectonic alteration phenomenon. 2 geological features The exposed strata Tamu mine mainly the Lower Carboniferous Kara Brazil Tucker group (C1k1). The strata in the mining area can be divided into three lithologic the: first lithologic of gray thicklayered fragmentation dolomitic, argillaceous, siliceous limestone, is an important orebearing horizon。 second lithologic gray and black calcareous shale。 lithologic gray) thinbedded limestone, sandy limestone, rich in fossils (Figure 1). Geological map of Tamu leadzinc deposit The deposit consists of five ore bodies, produced in Kara Brazil Tucker lithologic, a wider range of mineralization (about 800 m, width up to 40m), but only 1 orebody with industrial significance. (1) ore body characteristics: stratiform, branching phenomenon, the occurrence and the surrounding rock is basically the same. Par。
