The Mechanisms and Kinetics of the Fe2Si04 Olivine- Spinel Transformation and Its Implications for Deep Slab Processes

9304791获得pi将研究组成Fe2SiO4的橄榄石-尖晶石转变的机理和动力学规律。这个实验项目将利用科罗拉多大学的一个气体活塞缸装置的独特能力。该装置在以前无法达到的范围内提供了非常众所周知的静水压力。差应力也可以很好地表征。目标是提高对俯冲板块中氧化铁矿物相变过程的理解，并对转换断层的物理学有更深入的了解。

9304791 Getting The PIs will study the mechanisms and kinetic laws of the olivine-spinel transformation of the composition fayalite Fe2SiO4. This experimental program will exploit the unique capabilities of a gas piston-cylinder apparatus at the University of Colorado. This device offers extremely well known hydrostatic pressure in a range previously inaccessible. Differentia stresses can also be well characterized. The goal is to improve understanding of the processes of phase change in ferromagnesian minerals in subducting slabs and to develop greater insight into the physics of transformational faulting.
