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成矿流体，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时，流体的物理化学条件发生跳跃式突变而成矿。
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.
