MRI-RUI: Acquisition of a scanning electron microscope and energy dispersive X-ray spectrometer

0320639销售这一重大研究仪器(MRI)计划赠款支持高露洁大学地质学系购买JEOL JSM-6360 LV扫描电子显微镜(SEM)，配备CL和BSE探测器，用于对各种地质材料进行成像和分析。该设备将取代1986年购买的陈旧的扫描电子显微镜。新设备将与2002年春季用大学资金购买的新的PGT SPIRIT能量色散X射线分析系统(EDS)对接。一些地质研究项目严重依赖新的扫描电子显微镜系统，包括阿拉斯加、南极洲和纽约的古气候研究；酸化土壤系统中矿物与植物的相互作用；古砂岩中的埋藏成岩作用和胶结作用；格伦维尔造山带(包括热液系统)的岩石学和构造研究；以及恐龙蛋的埋葬分类。高露洁大学的本科生地质学研究是课程作业的一部分，也是高级独立项目和论文的组成部分；新的扫描电子显微镜将为学生提供实践经验，使用最先进的分析仪器对天然材料进行高分辨率显微镜和微量化学分析。

0320639SelleckThis Major Research Instrumentation (MRI) Program grant supports acquisition of a JEOL Model JSM-6360 LV Scanning Electron Microscope (SEM) with CL and BSE detectors for imaging and analysis of a variety of geological materials in the Department of Geology at Colgate University. This equipment will replace an antiquated SEM purchased in 1986. The new equipment will be interfaced with a new PGT Spirit Energy Dispersive X-Ray Analysis System (EDS) purchased in spring 2002 with university funds. A number of geological research projects are critically dependent on the new SEM system including studies of paleoclimate in Alaska, Antarctica and New York; mineral-plant interactions in acidified soil systems; burial diagenesis and cementation in ancient sandstones; petrologic and tectonic studies of the Grenville Orogen (including hydrothermal systems); and burial taphonomy of dinosaur eggs. Undergraduate student research in Geology at Colgate is used as a component of coursework and for upper-level independent projects and theses; the new SEM will provide students with hands-on experience using state-of-the-art analytical instrumentation for high resolution microscopy and microchemical analysis of natural materials.
