| 摘 要： | 流体是地球内部物质和能量迁移最为活跃的介质，它在造成地幔化学的富集和亏损，产生具有不同地球化学特征的幔源岩浆岩石，以及促进壳幔物质的再循环过程等诸多方面都起了重大作用，高温高压下实验模拟流体与地幔岩石和矿物之间痕量元素分配作用是揭示地幔流体的组成与性质，地幔中不同元素类型之间或内部的分异作用，地幔交代介质的类型与特征，岛孤玄武岩高场强元素亏损原因的一个重要的手段，并对近年来有关高温高压下流体与地幔矿物之间痕量元素分配作用的实验模拟研究进行了评述，分析了制约流体与地幔矿物之间痕量元素分配系数的因素，总结了这些研究的应用。

| Abstract: | Mantle fluids are the most active mediums for mass and heat transport in the Earth's mantle. They play important roles in the enrichment and depletion of Earth's mantle and the origin of mantle derived magmatic rock with different geochemical features and facilitating the recycle of crustal and mantle's materials. The simulation of trace elements partitioning between mantle mineral and fluid is a useful tool to estimate the fluid composition in the Earth's mantle and constrain the role of fluid phases during metasomatic processes in the upper mantle and characterize crust/mantle recycling processes and explain the origin of high strength element depletions in arc magmas. In this article we review the recent progresses in the experimental studies of fluid/ mantle mineral trace element partitioning and analyze the controlling factors for mantle mineral/fluid trace element partitioning and summarize the applications of partitioning coefficients obtained from the high pressure and high temperature measurement. Despite the advances in our understanding of fluid/mineral partitioning, specific shortcomings exists in the database. Future research will surely have a significanly impact on our understanding of deep seated fluid. |
