EAR-0452220FolandThis project provides technical support to the Radiogenic Isotope Laboratory in the Department of Geological Sciences at Ohio State University on the main campus in Columbus. This laboratory conducts varied research that receives essential assistance and service by two skilled technicians with many years of experience. NSF funds together with matching from Ohio State University provide one FTE of combined annual technician salary. The Radiogenic Isotope Laboratory is housed in first-class physical space. It has facilities for sample processing and preparation, including a cleanroom suite, and for analysis with 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, and 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. A broad cross section of the varied research activities are undertaken by the PI and Ohio State University colleagues as well as a number of external scientists with on-going collaborative and cooperative projects. The central scientific objectives are both methodological and applied with current subjects ranging from environmental and hydrologic (e.g., Pb in drinking water, Sr in stream water) to paleoclimatic (e.g., Recent to Paleozoic) to diverse geological (e.g., basalt petrogenesis, thermochronology, micron Au deposits) to purely geochemical (e.g., Ar retention and behavior in minerals).

EAR-0452220Foland 该项目为哥伦布主校区俄亥俄州立大学地质科学系的放射性同位素实验室提供技术支持。 该实验室开展各种研究，并得到两名具有多年经验的熟练技术人员的重要协助和服务。 NSF 资金与俄亥俄州立大学的配套提供了一份 FTE 技术人员年薪。 放射性同位素实验室坐落在一流的物理空间中。 它拥有样品处理和制备设施，包括洁净室套件、热电离和惰性气体质谱仪分析设施，以及支持研究测量的全套辅助设备。 该实验室针对多种广泛的问题进行同位素地球化学和地质年代学研究。 当前研究的主要同位素系统是 Rb-Sr、Sm-Nd、U-Pb 和 K-Ca，还有 K-Ar，特别是 40Ar/39Ar 技术。 研究包括使用放射性同位素（例如 Sr、Nd 和 Pb）的同位素示踪剂研究和地质年代学测定（例如 40Ar/39Ar 和 Rb-Sr）。 总体而言，研究目标范围从基础和方法论到应用和主题。 PI 和俄亥俄州立大学的同事以及一些正在进行协作和合作项目的外部科学家开展了广泛的各种研究活动。 中心科学目标既是方法论的，也是当前学科的应用范围，从环境和水文（例如饮用水中的铅、溪流水中的锶）到古气候（例如近古生代）到各种地质学（例如玄武岩岩石成因、热年代学、微米金矿床）到纯粹的地球化学（例如矿物中的氩保留和行为）。
