0421452SampleWith support from this Major Research Instrumentation (MRI) grant, the Department of Geology at Northern Arizona will install a scanning electron microscope (SEM) optimized for elemental imaging and chemical analysis of rocks and minerals. This SEM will significantly enhance the existing geologic research capabilities in the Department. Faculty members in the Department of Geology will manage the facility, and a technician supported by the Department will provide maintenance and training for researchers and students. The Department has a successful program with 16 faculty members. Ten faculty members and their students use an SEM as part of their research program. The SEM will be an important tool for making more demanding analytical research (isotopic analysis by mass spectrometry, electron microprobe analysis) efficient and thorough, and in developing new avenues of research not practical with existing instrumentation at NAU. These research programs include investigations of magma chamber processes, fluid-rock interactions in fault zones at active margins, pressure-temperature-time evolution of orogenic belts, volcanic processes and eruptive fabrics, tectonics and sedimentary provenance of formations in the North American Cordillera, chemical and faunal evolution of cold seep systems at continental margins, and biostratigraphy and evolution of micro-vertebrates.Besides benefiting the strong research programs of Geology faculty members and their students, the SEM will be a valuable, user-friendly training tool for all graduate and undergraduate students interested in quantitative analysis of geological materials. This instrument will be used in educational and research training in at least 4 undergraduate and 12 graduate classes, impacting dozens of students in a large geology program. The SEM will provide the students graduating from NAU Geology with analytical skills that will help to ensure their success as they pursue more advanced degrees. The facility will provide important outreach capabilities for the Department to bring more students from the large rural Arizona, Native American, and Hispanic populations served by NAU, into a career in geoscience. In these ways, the SEM will serve a university whose mission is to be a premier undergraduate residential institution integrated with professional and graduate programs. The instrument will be housed in the Department of Geology where the proximity and fee structure will be favorable for innovative teaching- and research-related usage.

在这项主要研究仪器（MRI）拨款的支持下，北亚利桑那地质系将安装一台扫描电子显微镜（SEM），用于岩石和矿物的元素成像和化学分析。这台扫描电镜将大大提高本部门现有的地质研究能力。地质系的教职员工将管理该设施，地质系支持的技术人员将为研究人员和学生提供维护和培训。该系有一个成功的项目，有16名教员。10名教师和他们的学生使用SEM作为他们研究计划的一部分。扫描电镜将成为一个重要的工具，使更苛刻的分析研究（质谱分析的同位素分析，电子探针分析）高效和彻底，并在开发新的研究途径不实用的现有仪器在NAU。这些研究项目包括岩浆房过程、活动边缘断裂带的流体-岩石相互作用、造山带的压力-温度-时间演化、火山过程和喷发构造、北美科迪勒拉构造和沉积物源、大陆边缘冷渗系统的化学和动物演化、生物地层学和微型脊椎动物演化。除了有利于地质学教师及其学生的强大研究项目外，SEM将成为所有对地质材料定量分析感兴趣的研究生和本科生的有价值的，用户友好的培训工具。该仪器将用于至少4个本科生和12个研究生班的教育和研究培训，影响到一个大型地质学项目的数十名学生。SEM将为NAU地质学专业毕业的学生提供分析技能，这将有助于确保他们在追求更高学位时取得成功。该设施将为该部门提供重要的外联能力，使更多来自NAU服务的亚利桑那州广大农村地区、美洲原住民和西班牙裔人口的学生进入地球科学领域。通过这些方式，SEM将服务于一所大学，其使命是成为一个一流的本科住宿机构，与专业和研究生课程相结合。该仪器将被安置在地质学系，那里的距离和费用结构将有利于创新的教学和研究相关的使用。
