摘要
与构造环境密切相关的氧逸度是控制地幔流体成分的最根本因素CO2和H2O为大多数地幔流体的主要成分。俯冲板块的脱水脱气作用、地幔原始残留挥发份及地幔部分熔融作用是地幔流体的主要来源。
The basic-factor affecting the conent of mantle fluids is oxygen fugacity which is highly related to tectonic setting. Major components of mantle fluid are CO2 and H2O. Mantle fluids were mostly derived fromdehydration and degassing of a subducting slab, mantle original residual volatiles and partial melting of themantle.
