REU Site: Digital Mapping and Strain Analysis of Deformed Veins and Intrusions

PI将与9名本科生/年合作，使用最新的数字测量仪器，开发一系列高分辨率的地壳变形过程分析底图，这些变形过程在缅因州沿海露头中可见。 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地区的复杂结构历史，这些地区与Norumbega断层带上的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。 这两个选定的网站提供了广泛的曝光和复杂的应变历史与两个新认识的剪切区wihin的东南侧翼的主要诺伦贝加断层带。 将利用全球定位系统和电子全站仪收集数据，将变形结构特征的详细几何图形绘制到地理信息系统中。 该项目将包括一个为期六周的夏季研究会议，和秋季学期的独立研究，最终在摘要和海报上的合作工作，在专业会议上展示结果。

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.
