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.

小行星9316033 阿巴拉契亚山脉构造演化的大多数模型都涉及伴随着碰撞的俯冲阶段。 在最近发现榴辉岩之前，在阿巴拉契亚山脉南部缺乏俯冲或碰撞带典型的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，将为建立蓝岭演化模型提供结构-岩石学-年代学数据，特别是劳伦克拉通洋壳的侵位和构造关系。
