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.***

EAR-0549622 Van Orman该项目将提供资金购买多砧座高压设备，主要用于3至27 Gpa范围内关于结晶和液态硅酸盐、氧化物和金属中原子扩散的研究。获得一个多砧板装置将使我的团队能够获得与地球深部相关的各种高压阶段的扩散数据。这些实验数据将有助于理解地幔和地核中的化学传质、蠕变和滞弹性变形。使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之间的学科界限的信息。该设备对建立PI的高压研究计划至关重要，并将使凯斯西储大学研究生和本科生的研究和教育一体化。
