Elasticity of Mantle Minerals at High Pressures and Temperatures

低音9614416 PI提出了一项研究计划，通过布里渊光散射实验测量具有地球物理意义的矿物和高压硅酸盐的声速（弹性模量）。 这项工作的主要目标是测量金刚石压砧单元（DAC）中高压和高温下的速度和弹性模量。 这些数据对于限制地球内部的矿物学和化学性质是重要的，并且需要这些性质的衍生物， 以解开地幔的组成 详细 将结果与地震学确定的地幔速度进行比较，应能更好地了解地球的内部结构和组成。 ***

Bass 9614416 The PI proposes a research program to measure acoustic velocities (elastic moduli) of minerals and high-pressure silicates of geophysical interest by Brillouin light scattering experiments. The main thrust of the work will be measurement of velocities and elastic moduli at high pressures in the diamond-anvil cell (DAC), and at high temperatures. These data are important for placing constraints upon the mineralogy and chemistry of the earth's interior, and the derivatives of these properties are needed in order to unravel the composition of the Earth's mantle. Detailed comparisons of results with seismologically determined velocities for the mantle should yield an improved picture of the internal structure and composition of the Earth. ***
