对地幔中可能存在的含水矿物的稳定性进行高压实验，为地幔中水的分布及其储存形式提供了限制。然而，含水矿物之间的成分和结构一直存在混淆。在地幔温度升高的地区，水可能不是储存在含水矿物中，而是储存在无水矿物、熔体和流体中。这些水对于了解地幔、火山作用和交代作用的动力学和演化非常重要。本文对地幔中水的状态和运移进行了综述。
High-pressure experiments on the stability of hydrous minerals likely to be present in the Earth's mantle provide constraints on the distribution of water in the mantle, and the form in which it is stored. However, there has been confusion about compositions and structures between hydrous minerals. In regions of elevated mantle temperature, water may be stored not in hydrous minerals but in anhydrous minerals, melts, and fluids. Such water is important to understand the dynamics and evolution of the mantle, volcanism, and metasomatism. In this article, the state and migration of water in the mantle are reviewed.
