Structural History of the Columbus Promontory, Western Piedmont, Southern Appalachians: Thrust Faulting Processes in the Middle Crust of a Paleozoic Orogen

南部的蓝岭-山麓逆冲岩席 阿巴拉契亚山脉是一个复合冲断岩席的典型例子 几个事件产生的，但安置的历史，及其 与变质作用的关系及深圳湾岩体的形成时代不甚明确 受约束。 该项目将调查一个相对较好的- 暴露的地区-哥伦布岬-为了解决 断层就位力学和物理条件 在几个尺度上发展。 现场制图，结构数据， 岩体和断层岩的放射性年龄数据，以及 地热测压数据将被收集和使用， 努力约束这些大型结构，并辨别它们的 进化

The Blue Ridge-Piedmont thrust sheet of the southern Appalachians is a "type example" of a composite thrust sheet produced by several events, yet the emplacement history, and its relationship to metamorphism and ages of plutonism are not well constrained. This project will investigate a relatively well- exposed area- the Columbus Promontory- in order to address emplacement mechanics and physical conditions of fault development on several scales. Field mapping, fabric data, radiometric age data of plutons and fault rocks, and geothermobarometric data will be collected and employed in an effort to constrain these large structures and discern their evolution.
