Abstract:Based on the characteristics of lead—zinc deposits which located in the different types of continental collision orogenic belt, in main collision stage of continental collision, the foreland basin has formed in one side or both sides of the different types of collision orogenic belt as the flexural subsidence of continental crust by compression of the massif. Then, the undeformed or weakly deformed carbonate platform has formed in the sedimentary basin. The brine from sedimentary basin was drived by the gravity because of orogenic uplift, converged to the edge of the basin, extracted oreforming elements of basins, flowed to carbonate karst or fracture in the edge of the basin, formed the MVT lead—zinc deposits. In the slip transformation stage of late collisional period, the brine from basin and formation water extracted oreforming minerals of strata or basement rocks and formed oreforming fluid. The sustained force of compression from continental collision drived the oreforming fluid lateral fluxion, simultaneity, made the basin intense deformation and formed a series thrust system. The sedimenthosted lead—zinc polymetallic deposits which possesses special characteristics has formed in the thrust fault and its associated secondary strikeslip fault or tensional fault when short stretching phase after continental collision. The vein lead—zinc deposits was produced in the collision orogen metamorphic terrane similar to deposits which were formed in the Qinling collision orogenic belt, as oreforming poured into tensile structure during compression to extend transformation stage .
