这项研究将使用一种特殊的高压装置来研究高压和高温下地幔材料相变的机制和动力学,该装置设计的目的是在高压和温度下对样品施加受控剪应力。样品将通过光学显微镜、使用同步辐射的高压和高温下的原位X射线衍射以及事后电子显微镜和微探针分析进行检查。关于地幔物质在地幔过渡带压力和温度下的动力学行为的实验信息将对理解深源地震的起源和性质非常有价值。
英文摘要
The study will investigate the mechanisms and kinetics of phase transitions in mantle materials at high pressures and temperatures using using a special high pressure apparatus designed to apply a controlled shear stress to the sample while at high pressure and temperature. The sample will be examined by optical microscope, in situ x-ray diffraction at high pressures and temperatures using synchrotron radiation, and post mortem electron microscope and microprobe analyses. Experimental information on the dynamic behavior of mantle materials at pressures and temperatures that exist within the transition zone of the mantle will be very valuable for understanding the origin and nature of deep focus earthquakes.
