The PI's will work with 9 undergraduates/year using the latest digital survey instruments to develop a series of high-resolution analytical base maps of crustal deformation processes visible in outcrops of coastal Maine. This two-year summer research program of precision mapping and strain analysis will document the complex structural history of two key outcrop areas in relation to regional strain accommodation due to strike-slip shearing on the Norumbega fault zone as depicted in the geometry of deformed veins and intrusions. Both selected sites offer extensive exposure and complex strain histories associated with two newly recognized areas of shear wihin the southeast flank of the main Norumbega fault zone. Detailed geometries of deformed structural features will be mapped into a geographic information system (GIS) using global positioning systems (GPS) and electronic total stations for data collection. The project will include a six-week summer research session, and a fall semester independent study culminating with collaborative work on abstracts and posters for presentation of results at a professional meeting.

PI 每年将与 9 名本科生合作，使用最新的数字测量仪器来开发一系列在缅因州沿海露头可见的地壳变形过程的高分辨率分析底图。 这个为期两年的夏季精密测绘和应变分析研究计划将记录两个关键露头区域的复杂结构历史，这些区域与诺伦贝加断层带上走滑剪切引起的区域应变调节有关，如变形脉和侵入体的几何形状所示。 这两个选定地点都提供了与诺伦贝加主断层带东南侧两个新认识的剪切区域相关的广泛暴露和复杂的应变历史。 使用全球定位系统（GPS）和电子全站仪进行数据收集，将变形结构特征的详细几何形状映射到地理信息系统（GIS）中。 该项目将包括为期六周的夏季研究课程和秋季学期的独立研究，最终以在专业会议上展示结果的摘要和海报的协作工作为高潮。
