0932992Ito"This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5)." This proposal will fund a petrographic microscopy system and an SEM-EDX upgrade for rapid sediment core characterization at the Lacustrine Core Facility. The SEM with EDX/EDS elemental analysis will be user friendly and table top to facilitate core analysis. The LacCore facility will be able to offer new capabilities for characterizing new and stored cores. The main advantage of the currently requested instrument is that the PIs will be able to better characterize sediment cores in a non-invasive manner. This will facilitate prioritizing core ranges for sub-sampling and expensive detailed analysis. The proposed petrographic microscope will be used to gain better phase and mineral orientation information. The instrumentation will be incorporated into a generalized analysis scheme which will aid in sample prioritization and efficient analysis. The instrumentation will offer enhanced visualization and stimulate public outreach and student recruitment. The instruments will be incorporated into a summer microscopy camp for middle and high school students. High school students will be trained and allowed to run the instruments. The SEM will be incorporated into an undergraduate laboratory class at UM. ***

该奖项是根据《2009年美国复苏和再投资法案》(公法111-5)资助的。这项提议将资助岩相显微镜系统和扫描电子显微镜-EDX升级，以便在湖心设施进行快速沉积物岩心表征。带有EDX/EDS元素分析的扫描电子显微镜将是用户友好的和桌面，以方便岩心分析。LacCore设施将能够提供新的能力来表征新的和存储的核心。目前所要求的仪器的主要优点是，PI将能够以非侵入性方式更好地描述沉积物岩心的特征。这将有助于确定次级抽样和昂贵的详细分析的核心范围的优先顺序。所提出的岩相显微镜将被用来获得更好的物相和矿物取向信息。该仪器将被纳入一个通用分析方案，这将有助于确定样品的优先顺序和有效分析。该仪器将提供增强的可视化，并刺激公众宣传和招生。这些仪器将被纳入初中生暑期显微镜夏令营。高中生将接受培训，并被允许操作乐器。扫描电子显微镜将被纳入密歇根大学的一个本科生实验班。***
