Phase Transformations in Mantle Minerals

高温高压下地幔矿物的相变在地球内部的静态和动态过程中起着重要作用，特别是在350-700公里深度的上地幔向下地幔过渡带。这一行动为以下两个项目的研究提供了资金：(1)高压相弹性性质的压力依赖性；(2)相变的动力学和机制。这些实验将是石溪高压实验室的大容量高压设施。

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.
