Mechanisms of High Pressure Phase Transformations Between the Alpha, Beta and Gamma Polymorphs of Mg2SiO4 and (Mg,Fe)2SiO4

首席研究员将利用多砧仪器和透射电子显微镜技术，研究镁和镁铁橄榄石在各种压力和温度条件下的相变机理。这些结果将对理解地幔上部的动力学，包括俯冲洋板块的流变行为和深震源地震的机制具有重要意义。

The principal investigator will study the mechanisms of the phase transformations in magnesium and magnesium-iron olivine under a wide range of pressure and temperature conditions, employing multi anvil apparatus and transmission electron microscope techniques. The results will have important implications for understanding the dynamics of the upper part of the Earth's mantle, including the rheological behavior of subducting oceanic slabs and the mechanisms of deep focus earthquakes.
