Deformation Mechanisms, Microstructures, and Rheology of Experimentally Deformed Quartzo-Feldspathic Aggregates

高温变形的实验研究 长石和石英的单相和多相聚集体， 对于提供中下地壳的力学数据至关重要 岩石，并允许解释机制， 从保存的微观结构变形的条件。 长石是地壳中含量最丰富的矿物， 它们的耐火性质以及化学和结构的复杂性。 PI将根据他们在这方面的经验， 高温变形试验研究 详细的光学和传输补充 电子显微镜表征。

Experimental studies of the high temperature deformation of single and polyphase aggregates of feldspar and quartz are essential for providing mechanical data for mid to lower crustal rocks, and for allowing interpretations of mechanisms and conditions of deformation from preserved microstructures. Feldspars constitute the most abundant phase in the crust, but their refractory nature and chemical and structural complexity. The PIs will build on their experence in this area, and conduct experimental studies of high temperature deformation of feldspars, complemented by detailed optical and transmission electron miroscopic characterization.
