Ebullition of the Residual Magma and Sn-W Mineralization
残浆沸腾与锡钨成矿作用

A violent ebullition occurred in late residual magma of the S_type granite related to.Sn-W mineralization,and induced the generation of Sn and W ore_forming fluids of high temperature,high pressure,high salinity and high density.The fluids followed a path of stress difference,temperature difference,salinity difference and density difference for lateral migration or vertical migration in a relatively enclosed environment.The physicochemical condition experienced a jumping mutation, so that fluids precipitated and formed deposits when they were transported to the place where stress was released.
