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.

首席研究员将研究造岩矿物的相变。具体来说，他将利用透射显微镜、单晶和粉末 X 射线衍射、阻抗和量热技术记录杂质含量和应变场对转变过程的影响，以便建立不纯和有缺陷晶体在高温下的行为。技术。总的来说，他希望更好地了解在升高的临界温度下地球材料中发生自发结构扭曲的驱动机制。
