Elasticity and Shear Strength of Earth Materials at High Pressure

小行星9725395 矿物在高压和高温下的弹性性质对于固体地球物理学和矿物学中的一系列问题具有根本意义。 私家侦探。 将在35 GPa和1000摄氏度下使用金刚石压砧单元中的Brillioun散射测定矿物的单晶弹性特性。 还将进行新的同步加速器X射线衍射实验，以限制地球材料的强度和弹性。 将进行外部和激光加热实验以确定晶体结构和相图。 研究结果将用于改进地球深部组成和结构的模型。 ***

9725395 Duffy The elastic properties of minerals at high pressures and temperatures are of fundamental significance for a range of problems in solid Earth geophysics and mineralogy. The P. I. will determine single-crystal elastic properties in minerals to 35 GPa and 1000 degrees C using Brillioun scattering in the diamond anvil cell. New synchrotron x-ray diffraction experiments will also be conducted to constrain strength and elasticity of Earth materials. External and laser heating experiments will be conducted to determine crystal structures and phase diagrams. The results will be used to develop improved models of deep Earth composition and structure. ***
