Technician Support: Ohio State University, Radiogenic Isotopes Laboratory - Phase I

0137546 Foland该赠款为俄亥俄州州立大学地质科学系放射性同位素实验室的技术援助提供三年的部分工资支持。 放射性同位素实验室是一个现代化的设施，拥有一流的新物理设施，包括一个洁净室和热电离和惰性气体质谱仪，以及一整套辅助设备，以支持研究测量。 该实验室对各种广泛的问题进行同位素地球化学和地质年代学研究。 目前研究的主要同位素体系有Rb-Sr、Sm-Nd、U-Pb、K-Ca和K-Ar，特别是40 Ar/39 Ar技术。 研究包括同位素示踪研究，使用放射性同位素（例如，Sr、Nd和Pb）和地质年代学测定（例如，40Ar/39Ar和Rb-Sr）。 总体而言，研究目标范围从基础和方法到应用和专题。 除了PI和校内的同事和学生，实验室还被大量的校外专业人员和学生利用，无论是作为客工还是通过发送样本进行分析。 PI和俄亥俄州州立大学的同事以及一些外部科学家的研究活动与正在进行的合作和合作项目是相当不同的。 主题范围从地质和地球化学地球科学到环境和生物医学。

0137546FolandThis grant provides three years of partial salary support for technical assistance in the Radiogenic Isotope Laboratory in the Department of Geological Sciences at the Ohio State University. The Radiogenic Isotope Laboratory is a modern facility with new, first-class physical facilities that house a clean room and both thermal-ionization and noble-gas mass spectrometers, plus a full array of ancillary equipment, to support the research measurements. The laboratory conducts isotope geochemical and geochronologic research on diverse and wide-ranging issues. The principal isotopic systems of current investigation are Rb-Sr, Sm-Nd, U-Pb, K-Ca and also K-Ar especially with the 40Ar/39Ar technique. Studies include both isotope tracer research, using the radiogenic isotopes (e.g., Sr, Nd, and Pb), and geochronologic determinations (e.g., 40Ar/39Ar and Rb-Sr). Overall, the research objectives range from the fundamental and methodological to the applied and topical. In addition to the PI and intramural colleagues and students, the laboratory is utilized by a large number of extramural professionals and students, either as guest workers or by sending specimens for analysis. Research activities of the PI and Ohio State University colleagues as well as a number of external scientists with on-going collaborative and cooperative projects are quite varied. The topics range from geological and geochemical earth science to environmental and biomedical.***
