9413102 McWilliams This award provides partial funding for the acquisition of a high-mass resolution, high-transmission ion microprobe that will be installed and operated in the School of Earth Sciences at Stanford University. Stanford University is committed to providing the remaining funds needed for the acquisition of the instrument. The ion microprobe will be used primarily in research projects in isotope geochemistry, cosmochemistry, geochronology, and materials science. The facility will be open to scientists from Stanford University, the U.S. Geological survey, and other research institutions. The new design ion microprobe will be capable of quantitative in situ measurements of isotopic and elemental compositions of geological materials with micron scale spatial resolution in three dimensions and high sensitivity. *** 9406684 Johnson This award provides partial funding for the support of a technician assigned to the Radiogenic Isotope Laboratory in the Department of Geology and Geophysics at the University of Wisconsin, Madison. The technician will assist in the operation and maintenance of the laboratory's equipment that includes a multicollector thermal ionization mass spectrometer and associated instrumentation for sample preparation and data analysis. The laboratory is a resource for mass spectrometric analysis needed in research and teaching projects in the earth sciences by a large number of researchers on-campus and off-campus. Research applications include work on Arctic Ocean sediments, mantle geochemistry, volcanism, geochronology of carbonates in the Michigan Basin and Wisconsin Arch provinces, and Archean and Proterozoic granites. The technician will also participate in the technical developmental work of the laboratory, including the development of new methods for the quantitative measurement of the isotopes of hafnium. ***

9413102 McWilliams 该奖项为购买高质量分辨率、高传输离子微探针提供部分资金，该探针将在斯坦福大学地球科学学院安装和运行。斯坦福大学致力于提供购买该仪器所需的剩余资金。 离子微探针将主要用于同位素地球化学、宇宙化学、地质年代学和材料科学的研究项目。该设施将向斯坦福大学、美国地质调查局和其他研究机构的科学家开放。新设计的离子微探针将能够对地质材料的同位素和元素组成进行原位定量测量，具有三维微米级空间分辨率和高灵敏度。 *** 9406684 Johnson 该奖项为威斯康星大学麦迪逊分校地质和地球物理系放射性同位素实验室的一名技术人员提供部分资金支持。技术人员将协助操作和维护实验室设备，包括多接收器热电离质谱仪以及用于样品制备和数据分析的相关仪器。该实验室是校内外大量研究人员进行地球科学研究和教学项目所需的质谱分析的资源。研究应用包括北冰洋沉积物、地幔地球化学、火山活动、密歇根盆地和威斯康星拱门省的碳酸盐地质年代学以及太古代和元古代花岗岩。该技术人员还将参与实验室的技术开发工作，包括开发铪同位素定量测量的新方法。 ***
