Elasticity of High Pressure Phases of Mantle Minerals

在高压和高温下，地幔矿物的相变强烈地影响着地球内部的物理性质和动态过程。本实验室计划的目的是利用超声技术结合同步加速器x射线辐射研究地幔矿物高压相的弹性特性。然后，新的弹性数据将被用于解释地幔的化学成分和矿物学方面的地震模型。这项研究计划利用了石溪高压实验室的多砧、大容量设施和美国国家科学基金会高压研究技术中心（CHiPR）的相关分析设施以及附近布鲁克海文国家实验室的国家同步加速器光源提供的特殊机会。

Robert C. Liebermann 9980451 Phase transformations in mantle minerals at high pressures and temperatures strongly influence the physical properties and dynamic processes in the Earth's interior. The objective of this laboratory program is to study the elastic properties of high-pressure phases of mantle minerals using ultrasonic techniques in conjunction with synchrotron X-radiation. The new elasticity data will then be used to interpret seismic models of the Earth's mantle in terms of chemical composition and mineralogy. This research program takes advantage of the special opportunities provided by the multi-anvil, large-volume facilities of the Stony Brook High Pressure Laboratory and the associated analytical facilities of the NSF Science and Technology Center for High Pressure Research (CHiPR), as well as those of the National Synchrotron Light Source at the nearby Brookhaven National Laboratory.
