中文摘要
变质岩石学的发展使我们能够确定许多变质岩石的压力、温度和时间路径,然而伴随的变形通常以各种鲜为人知的方式影响这些估计,有时导致不正确或误导性的结果。该项目的目标是详细检查在阿尔卑斯山暴露的角闪岩相剪切带中变质和变形过程之间的相互关系,该剪切带显示出各种剪切和平坦结构。结果将用于开发一套纹理指南,以区分从变形岩石中获得有意义的压力温度条件计算的样品与产生虚假结果的样品。变形过程、成分和织物将用于估计这些参数对所涉及的岩性的公牛流变性的影响。这项工作在许多变质作用和变形过程同步进行的地区具有相当重要的意义。
英文摘要
Selverstone0000965Developments in metamorphic petrology allow pressure, temperature time paths to be determined for many metamorphic rocks, however accompanying deformation commonly affects these estimates in a variety of poorly understood ways, sometimes leading to incorrect or misleading results. The goal of this project is to examine in detail the interrelationships between metamorphic and deformational processes is an amphibolite-facies shear zone exposed in the Alps that exhibits a variety of shear and flattening fabrics. Results will be used to develop a set of textural guidelines for distinguishing between samples that allow meaningful calculation of pressure temperature conditions from deformed rocks vs. those that yield spurious results. Deformation processes, compositions and fabrics will be used to estimate the effect these parameters have on bulls rheologies of the lithologies involved. This work has considerable importance in many areas where processes of metamorphism and deformation have operated synchronously.
