Microstructural Investigations of Phase Transitions in Rock-Forming Minerals

首席研究员将研究岩石的相变- 形成矿物质具体来说，他将记录 杂质含量和应变场对相变过程的影响 为了确定不纯和有缺陷的晶体的行为 在高温下，利用透射显微镜， 晶体和粉末X射线衍射、阻抗和量热 技术.总的来说，他希望能更好地了解 导致了地球上自发的结构扭曲 在升高的临界温度下的材料。

The principal investigator will study phase transitions in rock- forming minerals. Specifically, he will document the effects of impurity content and strain fields on the transformation process in order to establish the behavior of impure and defective crystals at high temperature, utilizing transmission microscopic, single- crystal and powder X-ray diffraction, impedence, and calorimetric techniques. In general he hopes to better understand the mechanisms that drive spontaneous structural distortions that occur in Earth materials at elevated critical termperatures.
