9404658 London This award provides 55 per cent of the funding required for the upgrade of an electron microprobe system at the School of Geology and Geophysics at the University of Oklahoma. The University is committed to providing the remaining funds necessary for the equipment upgrade, which will consist of modern computer automation of stage movement and analytical functions, installation of x-ray diffracting composite detectors for analysis of light elements, and a sputter coater for carbon coating of non conducting specimens. The upgraded system is needed to meet the needs of a diverse user base at the University of Oklahoma who rely on the electron microprobe for chemical microanalysis of geological and other material samples. Specific projects needing the capabilities of a modernized electron microprobe include: (1) quantitative spatial analysis of the organic, mineral, and trace elemental constituents of coals, including a quantitative assessment of the correlation among maceral composition, optical reflectance, and back scattered electron signal intensity, (2) spatial analysis of rocks forming reservoir rocks for hydrocarbon and water, and (3) microscale studies of minerals grown from late-stage magmatic fluids and gases. *** 9405805 Craig This award provides 75% of the funds required for the acquisition of a microscope system for use with transmitted and reflected light to be used in the rare gas isotope laboratory, Scripps Institution of Oceanography at the University of California, San Diego. The University is committed to providing the remaining funds necessary for the acquisition. The microscope system is mainly to be used by researchers working with fluid, glass, and crystalline inclusions trapped in samples of basaltic rocks that have been extruded from the Earth's mantle. The microscope is needed for the location and identification of these small inclusions prior to extraction of the rare gases (argon, helium, and neodymium) for isotopic analysis. The researchers at the Scripps Institution of Oceanography are using the isotopic content of the rare gases brought up from the mantle to understand the geochemical evolution of the mantle. ***

9404658伦敦 该合同提供了俄克拉荷马州地质和地球物理学院电子微探针系统升级所需资金的55%。该大学承诺提供设备升级所需的其余资金，其中包括载物台移动和分析功能的现代计算机自动化，安装用于分析轻元素的X射线衍射复合探测器，以及用于非导电样品碳涂层的溅射镀膜机。升级后的系统需要满足俄克拉荷马州大学不同用户群的需求，他们依赖电子探针对地质和其他材料样品进行化学微量分析。需要现代化电子探针能力的具体项目包括：（1）煤的有机、矿物和微量元素成分的定量空间分析，包括显微组分成分、光学反射率和背散射电子信号强度之间的相关性的定量评估，（2）形成烃和水的储集岩的岩石的空间分析，（3）晚期岩浆流体和气体中矿物生长的微观研究。 克雷格 该奖项提供了75%的资金，用于购买一个显微镜系统，用于传输和反射光，用于稀有气体同位素实验室，斯克里普斯海洋学研究所在加州，圣地亚哥大学。该大学致力于提供收购所需的剩余资金。 显微镜系统主要用于研究从地幔中挤出的玄武岩样品中捕获的流体，玻璃和结晶包裹体的研究人员。在提取稀有气体（氩、氦和钕）进行同位素分析之前，需要使用显微镜来定位和识别这些小包裹体。斯克里普斯海洋研究所的研究人员正在利用从地幔中携带的稀有气体的同位素含量来了解地幔的地球化学演化。 ***
