Eclogite from the Blue Ridge Thrust Complex, Western North Carolina: New Constraints on Tectonics and High-Pressure Metamorphism

9316033巴特勒大多数阿巴拉契亚山脉的构造演化模式都包括俯冲和碰撞的阶段。直到最近发现榴辉岩之前，在阿巴拉契亚山脉南部缺乏典型的俯冲或碰撞带高压变质作用的证据。该项目是对北卡罗来纳州蓝岭生态岩的深入研究，将为开发蓝岭演化模型，特别是劳伦斯克拉通洋壳的侵位和构造关系提供结构-岩石学-年代学数据。

9316033 Butler Most models of the tectonic evolution of the Appalachians involve stages of subduction accompanied by collision. Until the recent discovery of eclogite, evidence of the high-pressure metamorphism typical of subduction or collision zones was lacking in the southern Appalachians. This project is an in-depth study of the ecologite in the North Carolina Blue Ridge, and will provide structural-petrologic-chronlogic data for developing models for the evolution of the Blue Ridge, in particular the emplacement and tectonic relationships of oceanic crust on the Laurentian craton.
