关于变质流体组成的大多数研究仅考虑存在的主要气体种属,但含水流体也能携带相当数量的溶解物质(在中至高级变质条件下,主要是呈氯化物络合物形式),而在绿片岩相或较低温度下,主要种属(一般是NaCl)又会发生明显分解。只要能够对流体相的总氯含量, Most of the studies on the composition of metamorphic fluids consider only the major gas species present, but aqueous fluids can also carry significant amounts of dissolved matter (mostly in the form of chloride complexes under moderate to high metamorphic conditions) Greenschist facies or lower temperature, the main species (usually NaCl) will be significantly decomposed. As long as the total chlorine content of the fluid phase,
