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.

该项目涉及复杂的构造地质， 美国缅因州的海岸带，从新罕布什尔州到新玩法， 一个大型区域走滑断裂系统的发育及其 与中晚期斜向辐合的关系 古生代的。 它集中在一个包含两个大断层的地区 （Norumbega和Nonesuch河断层）和连接 他们 这项工作涉及详细的结构分析， 断层和过渡区，并将试图确定应变 断层相互作用的数量和运动学机制。 结果 对区域构造的故事很重要， 但也有兴趣从微观结构 过程相关的观点。
