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.

Liebermannouncement-0229704地震学调查产生了关于地球内部声波速度的最精确信息。 矿物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。该项目将利用超声技术与同步加速器X辐射相结合，测量地幔矿物在同时高压和高温下的声速。 该研究计划利用了斯托尼布鲁克高压实验室的多砧大容量设施和斯托尼布鲁克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。 其中许多设施是在1991年至2002年期间在NSF高压研究科学技术中心（CHiPR）的赞助下开发的。
