地幔中水的赋存状态的研究进展

地幔水不仅对地球物理场的性质有重要影响，而且对地球化学动力学，地幔横向不均一性、地幔对流、低速层、板块俯冲、相平衡、熔融行为、深部地质灾害以及成矿作用等都具有重要意义，因此，地幔水的研究早已引起人们的重视。为了探讨水在地幔过程中的作用，必须搞清楚水的赋存状态。研究表明，地幔中水的储存形式主要有三种：以ＯＨ形式储存的矿物中，以自由相形式存在以及溶解在熔体中，本文对地幔中水的赋存状态研究进展作了综述，

ADVANCE IN STUDY ON STORAGE SITES OF WATER IN THE MANTLE

Water in the mantle has an important influence on not only the nature of geophysicalfields, but also geochemical dynamics,mantle transverse heterogeneity,mantle convection,low velocity layer,subduction zone, phase equilibrium,the behavior of melting , deep geo-logical calamity(earthquake and volcanic eruption)and mineralization. So researchers hadpaid attention to study on water in the mantle for a long time. In order to discuss the roleof water in the mantle,it is necessary to get a clear understanding of storage sites of wa-ter. Early studies show that there are three main storage sites of vvater in the mantle:hydroxyl(OH)in minerals,as free fluid,Or in melts,This paper summarizes advance in studyon storage sites of water in the mantle and puts forward some proposals of future study di- rections.
