Phase Transformations in Mantle Minerals

高压下地幔矿物的相变 温度在静态和动态中起着重要作用 地球内部的过程，特别是在过渡时期， 从上地幔到下地幔的区域，深度在350到 七百公里。 这项行动为支持研究提供资金 重点研究了两个项目的性质和过程 与这些多晶型相变有关（1） 高压下弹性性质的压力依赖性 相;（2）相变动力学和机制。 这些实验将是大体积，高压 斯托尼布鲁克高压实验室的设施。

Phase transformations in mantle minerals at high pressures and temperatures play a major role in the static and dynamic processes of the Earth's interior, especially in the transition zone from the upper to the lower mantle at depths between 350 and 700 km. This action provides funds for support of research focused on two projects to study the properties and processes associated with these polymorphic phase transformations (1) Pressure dependence of the elastic properties of high-pressure phases; and (2) kinetics and mechanisms of phase transformations. These experiments will be the large-volume, high-pressure facilities of the Stony Brook High Pressure Laboratory.
