Regional Strain Accommodation and Fault Kinematics of the Norumbega-Nonesuch River Strike-Slip Fault System: Dextral Transpression in the Northern Appalachians

本项目研究缅因州从新罕布什尔州到新不伦瑞克省的沿海地带的复杂构造地质，主要区域走滑断层系统的发展及其与中晚古生代可能的斜向辐合的关系。它的重点是一个包含两个大断层（Norumbega和nonessuch河断层）和一个连接它们的复杂带的地区。这项工作包括对这些断层和过渡区进行详细的结构分析，并将试图确定断层相互作用的应变量和运动学机制。研究结果对区域构造故事很重要，包括外来地体的到来，但从微观构造过程相关的角度来看，也很有意义。

This project deals with the complex structural geology of the coastal belt of Maine from New Hampshire to New Brunswick, the development of a major regional strike-slip fault system and its relationship to possible oblique convergence during the Mid-late Paleozoic. It focuses on an area containing two large faults (Norumbega and Nonesuch River faults) and a complex zone linking them. The work involves detailed structural analysis of these faults and transition areas and will attempt to determine strain amounts and kinematic mechanisms for fault interaction. Results are important to the regional tectonic story, including the arrival of exotic terranes, but also is of interest from a microstructural process-related perspective.
