1625137CarmichaelThis Major Research Instrumentation (MRI) grant supports acquisition of a scanning electron microscope equipped with a high brightness electron source, an energy dispersive spectrometer, an electron backscatter diffractometer, and cathodoluminescence (CL) microscope to allow microscale textural and compositional imaging of solid earth, biological and synthetic materials as well as study of rock fabrics based on EBSD determination of crystallographic preferred orientation. The instrument will replace an aging SEM rapidly nearing the end of its serviceable life and will support research and research training Appalachian State University, a non-Ph.D. granting institution. This support is congruent with NSFs mission of promoting the progress of science and advancing the national health, prosperity and welfare given the importance of training the next generation scientific workforce in methods of analysis and scientific research methodologies. Appalachian State University is a primarily undergraduate institution and the investigators have a strong track record of engaging undergraduate students in laboratory and field research. Many of the students at Appalachian State are first-generation college students.The instrument will support and foster a range of investigator and student research including study of the role of microbes in manganese mineral formation, the geochemistry of mass extinctions, the extent of coal ash releases into river systems, the use of glacial grain roughness as a tracer for paleoclimate signals, applications to fission track thermochronology, thermobarometry, and analysis of deformation mechanisms to study dome formation in the Southern Appalachian mountains, the kinematics of faulting in the Southern Appalachians, plant root development, fluid-mineral reactions in volcanic ash, meteorite classification, metamorphism of ultra-high pressure systems, Ediacaran fossil assemblages, the effect of climate change on Fraser firs, vascular changes during pregnancy, the microbial ecology of peat bogs, and a variety of archaeological studies. ***

1625137 Carmichael该主要研究仪器（MRI）资助支持购买配备高亮度电子源的扫描电子显微镜，能量色散光谱仪，电子背散射衍射仪和阴极发光（CL）显微镜，以实现固体地球的微观结构和成分成像，生物和合成材料以及基于EBSD确定晶体择优取向的岩石组构研究。 该仪器将取代老化的扫描电镜迅速接近其使用寿命结束，并将支持研究和研究培训阿巴拉契亚州立大学，一个非博士学位。授予机构。 鉴于在分析方法和科学研究方法方面培训下一代科学工作者的重要性，这种支持与国家科学基金会促进科学进步和促进国家健康、繁荣和福利的使命是一致的。 阿巴拉契亚州立大学是一所主要的本科院校，研究人员在实验室和实地研究中有着良好的本科生参与记录。 阿巴拉契亚州立大学的许多学生都是第一代大学生。该仪器将支持和促进一系列调查人员和学生的研究，包括研究微生物在锰矿物形成中的作用，质量沉淀的地球化学，煤灰释放到河流系统中的程度，使用冰川颗粒粗糙度作为古气候信号的示踪剂，裂变径迹热年代学，热压测定法，和变形机制的分析，研究圆顶形成在南阿巴拉契亚山脉，断层运动学在南阿巴拉契亚山脉，植物根系发育，火山灰中的流体-矿物反应，陨石分类，超高压系统的变质作用，埃迪卡拉化石组合，气候变化对弗雷泽冷杉的影响，怀孕期间的血管变化，泥炭沼泽的微生物生态学，以及各种考古学研究。 ***
