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-0452220 Folandthis项目为俄亥俄州立大学哥伦布主要校园地质科学系的放射性同位素实验室提供了技术支持。 这项实验室进行了多种研究，从而获得了两位熟练技术人员的基本帮助和服务，并拥有多年的经验。 NSF资金以及俄亥俄州立大学的匹配提供了一份联合年度技术人员薪水。 放射性同位素实验室位于一流的物理空间中。 它具有样品处理和准备的设施，包括洁净室套件，以及用于热离子化和贵族气体质谱仪的分析，以及一系列辅助设备，以支持研究测量。 该实验室对各种和广泛的问题进行了同位素地球化学和地球学研究。 当前研究的主要同位素系统是RB-SR，SM-ND，U-PB和K-CA，以及K-AR，尤其是40AR/39AR技术。 研究包括同位素示踪剂研究，使用放射原同位素（例如SR，ND和PB）以及地球体学测定（例如40AR/39AR和RB-SR）。 总体而言，研究目标范围从基本和方法论到应用和局部。 PI和俄亥俄州立大学的同事以及许多外部科学家开展了各种研究活动的广泛横截面，并进行了持续的合作和合作项目。 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).
