Elasticity of High Pressure Phases of Mantle Minerals

地震学研究可以提供关于地球内部声波速度的最精确信息。对矿物中声速的实验室测量使这些地震数据能够根据化学成分、矿物学和温度进行解释。该项目将利用超声波技术结合同步加速器x射线辐射来测量同时在高压和高温下地幔矿物的声速。该研究项目利用了石溪高压实验室的多砧、大容量设施和石溪大学矿物物理研究所的相关分析设施提供的特殊研究机会。这些设施中的许多都是在1991-2002年国家科学基金会高压研究科学技术中心（CHiPR）的支持下开发的。

LiebermannEAR-0229704Seismological investigations yield the most precise information on the velocities of sound waves in the Earth's interior. Laboratory measurements of the sound velocities in minerals enable these seismic data to be interpreted in terms of chemical composition, mineralogy and temperature. This project will utilize ultrasonic techniques in combination with synchrotron X-radiation to measure the sound velocities of mantle minerals at simultaneous high pressures and temperatures. This research program takes advantage of the special opportunities for research that are provided by the multi-anvil, large-volume facilities of the Stony Brook High Pressure Laboratory and the associated analytical facilities of the Mineral Physics Institute at Stony Brook University. Many of these facilities were developed under the auspices of the NSF Science and Technology Center for High Pressure Research (CHiPR) from 1991-2002.
