| 中文摘要:与锡钨成矿作用有关的“Ｓ”型花岗岩，晚期残浆有强烈的沸腾作用，同时派生出高温、高压，高盐度和高密度锡钨矿流体，并遵循应力差，温度差，盐度差和密度差的轨迹，在相对封闭的环境中作侧向或垂向运移，当运移到应力释放部位一时，流体的物理化学条件发生跳跃式突变而成矿。 |

| Ebullition of the Residual Magma and Sn-W Mineralization |

| Abstract: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. |
