EAR-0549622Van OrmanThis project will provide funds for the purchase of a multi-anvil high pressure apparatus to be used primarily for studies in the 3 to 27 GPa range on atomic diffusion in crystalline and liquid silicates, oxides and metals. Acquisition of a multi-anvil device will allow my group to acquire diffusion data for a wide range of high-pressure phases relevant to Earth's deep interior. The experimental data will contribute to the understanding of chemical mass transfer, creep and anelastic deformation in Earth's mantle and core. Experiments performed with this new equipment will provide information that crosses disciplinary boundaries between geochemistry and geophysics. The equipment is vital to building the high-pressure research program of the PI, and will allow the integration of research and education of graduate and undergraduate students at Case Western Reserve University.***

该项目将提供资金购买一台多砧高压设备，主要用于在3至27 GPa范围内研究结晶和液体硅酸盐、氧化物和金属中的原子扩散。获得多砧装置将使我的小组能够获得与地球深层内部有关的各种高压阶段的扩散数据。实验数据将有助于理解地幔和地核的化学质量传递、蠕变和滞弹性变形。 用这种新设备进行的实验将提供跨越地球化学和地球物理学学科界限的信息。这些设备对于建立PI的高压研究计划至关重要，并将允许凯斯西储大学研究生和本科生的研究和教育相结合。
