The PI will investigate ductile deformation of polymineralic rocks with emphasis on evaluating inter and intragrain heterogeneities. Among polycrystal plasticity theories used to model deformation, the viscoplastic self-consistent theory is particularly attractive for anisotropic rocks. As a model system the PI plans to investigate first quartz in quartzo feldspathic rocks and use the development of preferred orientation as an indicative parameter in comparisons of models with experiments and naturally deformed rocks.

PI将研究多矿物的韧性变形 着重评价粒间和粒内的岩石 异质性 在多晶塑性理论中， 模型变形，粘塑性自洽理论是 对各向异性岩石特别有吸引力。 作为模型系统 PI计划调查石英石中的第一个石英 岩石并利用择优取向的发展作为 模型与实验比较的指示性参数 和自然变形的岩石。
