9731383 Green This grant provides partial salary support for a technician at the UC-Riverside Tectonophysics laboratory. This is a Phase II grant for technical support under the EAR/IF program. The technician is essentially a machinist who provides the necessary high precision fabrication of parts for continued development of Dr. Green's modified multianvil device used in studies of the deformation mechanics of deep mantle phases. This innovative and unique high pressure multianvil device introduces shear stresses on samples contained in a NaCl confining media, thereby reducing piston frictional effects and resultant spatial temperature variations within the sample volume. Experimental results using this device with germanate and titanate analogues of deep mantle silicates has resulted in Green's hypothesis that deep-focus earthquakes within subduction zones are the result of a phase change from olivine to a spinel polymorph. Work in the arena of high-pressure phase change initiation of faulting continues with synthetic silicates and improvements in the engineering design of Green's modified multianvil device. These experiments hold considerable promise for our understanding of deep earthquake mechanics. ***

9731383绿色 该补助金为加州大学河滨构造物理实验室的一名技术员提供部分工资支持。这是一个第二阶段的赠款，用于技术支持下的技术支持/综合框架方案。 技术人员基本上是一名机械师，为继续开发绿色博士的改良多砧装置提供必要的高精度零件制造，该装置用于研究深部地幔相的变形力学。 这种创新和独特的高压多砧装置在NaCl限制介质中包含的样品上引入剪切应力，从而减少活塞摩擦效应和样品体积内的空间温度变化。 实验结果使用这种设备与锗酸盐和钛酸盐类似的深地幔硅酸盐导致绿色的假设，深源地震俯冲带内的结果是一个相变从橄榄石尖晶石多晶型。 断层的高压相变引发的竞技场的工作继续与合成硅酸盐和改进绿色的修改多砧装置的工程设计。 这些实验为我们理解深层地震力学提供了相当大的希望。 ***
