This Division of Earth Sciences Instrumentation and Facilities Program award supports acquisition of a scanning electron microscope (SEM) to be housed in the Department of Earth and Environmental Sciences at University of Rochester. The SEM is capable of revealing minerals features and chemical composition at the micron-scale with magnification up to 100,000x and will be equipped with an energy dispersive spectrometer which permits spatially resolved compositional analysis. The SEM will be used to investigate the chemistry of synthetic minerals grown in the laboratory that seek to mimic mineral growth phenomena occurring in nature. The SEM will be small format and portable enabling student training in Earth and manmade materials characterization within classroom settings. Local outreach targeted at K-12 teacher training will also benefit from the acquisition.The SEM will support research in experimental igneous petrology including trace element mineral-melt partitioning studies, equilibrium isotope fractionation studies of synthetic and natural minerals, development of crystallization thermobarometers and oxygen fugacity determination methods The instrument will also support other University of Rochester laboratories including: (i) the laboratory for isotope geochemistry which performs measurements of radiogenic and stable isotope compositions of rocks and minerals to better understand history of Earth’s silicate reservoirs; (ii) the structural geology group who study the evolution of mountain belts at many different scales including microstructural analysis of cataclasites and mylonites to understand deformation mechanisms and kinematic evolution; and (iii) the paleomagnetic research group that focuses on the measurement of magnetic remanence (bulk magnetic properties, natural remanent magnetization) of a variety of materials.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这项地球科学仪器仪器设施计划奖支持收购在罗切斯特大学地球与环境科学系的扫描电子显微镜（SEM）。 SEM能够在微米尺度上揭示矿物质特征和化学成分，并具有高达100,000倍的放大倍数，并配备了能量分散光谱仪，该光谱仪允许空间分辨的组成分析。 SEM将用于研究实验室中生长的合成矿物质的化学，该化学试图模仿自然界中发生的矿物生长现象。 SEM将是小型格式和便携式，可在教室环境中进行地球和人造材料的培训。 Local outreach targeted at K-12 teacher training will also benefit from the acquisition.The SEM will support research in experimental igneous petrology including trace element mineral-melt partitioning studies, equilibrium isotope fractionation studies of synthetic and natural minerals, development of crystallization thermobarometers and oxygen fugacity determination methods The instrument will also support other University of Rochester laboratories including: (i) the laboratory for isotope geochemistry它对岩石和矿物质的放射原和稳定的同位素组成进行了测量，以更好地了解地球硅胶的历史（ii）结构地质群体，他们研究了许多不同尺度上山带的演变，包括大灾难岩和肌分离岩的微结构分析，以了解变形机制和KINEMATIC进化； （iii）侧重于测量各种材料的磁性避免磁性（体积磁性，自然遗物磁化）的古磁研究小组。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识优点和更广泛影响的审查标准来通过评估来通过评估来支持的。
