Water solubility of mantle minerals at high temperature and high pressure:a review

本文简要阐述地幔矿物中水溶解度的研究方法及过程,探讨晶体结构、化学组成、水逸度、温度、压力、氧逸度、硅活度等对溶解度的影响,结合橄榄石、辉石、石榴石、瓦兹利石、林伍德石等主要造岩矿物的研究成果,分析了地幔的储水能力,并指出存在的问题及今后的研究方向.

In this paper,we briefly elucidate the methods and process to research the water solubility of mantle minerals at high temperature and high pressure.Some potential influence factors on the water solubility of mantle minerals,such as crystal structure, chemical components, water fugacity,temperature,pressure,oxygen fugacity and silicate activity are discussed.The water solubility for the main rock-forming minerals in the upper mantle and transition zone e.g.olivine,pyroxene,garnet, wadsleyite,ringwoodite are reviewed.Furthermore,the capacity of water storage at different depth of the mantle is compared.Finally,we elaborate the existing problems of experimental research,and view the next-step work.
