总结了 2 0年来国内外学者对地幔流体研究的成果和认识。主要包括地幔流体的性质和组成 ;地幔流体中同位素的含量、组成和赋存形式 ;同位素分馏和地幔脱气等作用对地幔组分的影响等。在不同地区和不同构造环境条件的地幔流体中 ,各种组分含量和同位素组成变化可以很大 ,从一个侧面指示地幔组分的不均一性 ,反映了不同地幔物质的形成历程不同或来自不同的地幔源区。此外 ,还讨论了目前存在的几个疑点
The achievements and understandings of mantle fluid research by domestic and foreign scholars in 20 years are summarized. Mainly include the mantle fluid properties and composition; mantle fluid isotope content, composition and occurrence of forms; isotope fractionation and mantle degassing and other effects on the composition of the mantle and so on. In different regions and mantle fluids with different tectonic setting conditions, the contents of various components and isotopic compositions can vary widely, indicating the heterogeneity of the mantle components from one side, reflecting the different or different formation processes of different mantle materials Of the mantle source area. In addition, there are several doubts that exist at present
