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

PI将与9名本科生合作，每年使用最新的数字测量仪器开发一系列高分辨率的分析基础图，这些图可以在缅因州沿海露头中看到地壳变形过程。这个为期两年的夏季精确测绘和应变分析研究项目将记录两个关键露头区的复杂结构历史，这些露头区与Norumbega断裂带的走滑剪切引起的区域应变调节有关，如变形脉体和侵入体的几何形状所示。这两个选定的地点都提供了广泛的暴露和复杂的应变历史，与Norumbega主断裂带东南翼两个新发现的剪切区域有关。变形结构特征的详细几何形状将被映射到地理信息系统（GIS）中，使用全球定位系统（GPS）和电子全站仪进行数据收集。该项目将包括为期六周的夏季研究会议，以及秋季学期的独立研究，最后是在专业会议上展示结果的摘要和海报的合作工作。

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.
