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

PI将每年与9000名本科生合作，使用最新的数字测量工具，绘制一系列可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。这项为期两年的精确测绘和应变分析夏季研究计划将记录两个关键露头地区的复杂构造历史，这些地区与Norumbega断裂带上由于走滑剪切而导致的区域应变调节有关，如变形矿脉和侵入体的几何形状所描绘的那样。这两个选定的地点都提供了广泛的暴露和与两个新发现的剪切区有关的复杂应变历史，这些剪切区位于主要Norumbega断裂带的东南侧。变形结构特征的详细几何形状将被映射到使用全球定位系统(GPS)和电子全站仪进行数据收集的地理信息系统(GIS)中。该项目将包括为期六周的夏季研究会议和秋季学期的独立研究，最终将合作编写摘要和海报，以便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.
