项目摘要
This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).The Department of Geosciences at the University of Arizona will receive funds to build a new electron imaging facility to support the geochronological research of the Arizona LaserChron Center (ALC), and also to serve a broad range of research activities in the Departments of Geosciences and Planetary Sciences. The instrument to be purchased is a variable-pressure, tungsten filament scanning electron microscope equipped with secondary electron (SE), back-scattered electron (BSE), energy-dispersive spectrum (EDS), color cathodoluminescence (CCL) and electron back-scattered diffraction (EBSD) imaging and detection systems. The primary use for the scanning electron microscope will be to obtain BSE, color CL imaging, and trace element characterization of U-bearing accessory phases required for in situ geochronology at the ALC (an NSF Multi-User Facility). The images that will be obtained with the scanning electron microscope are critical to unravel the dates obtained from single U-bearing minerals, such as zircon by our laser ablation ICPMS National Facility. However, we also expect to support the research of others at The University of Arizona, where the SEM will yield images and elemental analytical data for: (1) Petrologic and geochemical studies of meteorites, (2) Identification of fossils and minerals for paleoclimate studies, (3) Identification of minerals, fluid inclusions, and textures and orientations for investigating petrogenesis, diffusion rates, and ore-forming processes, (4) Augmenting mineral composition and diffraction databases using coupled EBSD and EDS.
该奖项由2009年美国复苏和再投资法案(公法111-5)资助。亚利桑那大学地球科学系将获得资金,用于建造一个新的电子成像设施,以支持亚利桑那州激光计时中心(ALC)的地球年代学研究,并为地球科学系和行星科学系的广泛研究活动服务。购买的仪器是一台变压钨丝扫描电子显微镜,配备了二次电子(SE)、背散射电子(BSE)、能谱(EDS)、彩色阴极发光(CCL)和电子背散射衍射(EBSD)成像和检测系统。扫描电子显微镜的主要用途将是获得ALC(美国国家科学基金会多用户设施)现场地质年代学所需的含铀辅助相的BSE、彩色CL成像和微量元素表征。扫描电子显微镜将获得的图像对于解开由单一含铀矿物获得的数据至关重要,例如我们的激光消融ICPMS国家设施获得的锆石。然而,我们也希望支持亚利桑那大学的其他人的研究,在那里扫描电子显微镜将产生图像和元素分析数据,用于:(1)陨石的岩石学和地球化学研究,(2)用于古气候研究的化石和矿物的鉴定,(3)用于研究岩石成因、扩散速率和成矿过程的矿物、流体包裹体和结构和定向的鉴定,(4)利用耦合的EBSD和EDS来扩大矿物成分和衍射数据库。
