0420680DavidsonThis grant, made through the Major Research Instrumentation (MRI) program, provides support for acquiring a microanalysis system for an existing scanning electron microscope at Carleton College. The addition of a energy dispersive spectrometer based microanalysis system will greatly enhance the research, research training, and educational capabilities in Geology, Chemistry, Physics, and Anthropology at the college. Microanalysis is an essential tool for characterizing the chemical composition of solid materials at the micron scale. Current student and faculty research that will be enhanced by the acquisition of a new microanalysis system include 1) metamorphic petrology and tectonic studies in Southeast and south central Alaska; 2) evolution of Yellowstone volcanism; 3) characterization of sedimentary layers in early hominid sites in eastern Africa; and 4) investigations into the processes that control biogeochemical rates and species diversity in simple, microbially-dominated ecosystems. In addition, the new microanalysis system will be used in various courses to enhance the quantitative reasoning skills of science and non-science majors at the college.***

这项拨款通过主要研究仪器（MRI）计划获得，为卡尔顿学院现有的扫描电子显微镜获得微分析系统提供支持。新增加的以能量色散光谱仪为基础的微分析系统将大大提高学院在地质、化学、物理和人类学方面的研究、研究培训和教育能力。微量分析是在微米尺度上表征固体材料化学成分的重要工具。目前学生和教师的研究将通过获得一个新的微分析系统得到加强，包括：1)阿拉斯加东南部和中南部的变质岩石学和构造研究；2)黄石火山活动的演化；3)非洲东部早期古人类遗址的沉积层特征；4)研究控制微生物主导的简单生态系统中生物地球化学速率和物种多样性的过程。此外，新的微分析系统将用于各种课程，以提高学院理科和非理科专业学生的定量推理能力
