9304159 Halliday This award provides 45 percent of the funds required for the development of a mass spectrometer system that will combine a laser ablation sampling source with plasma ionization and a multi- collector magnetic sector mass spectrometer. The system will be developed to optimize analytical performance with respect to microanalytical spatial resolution as well as trace element and isotope sensitivity for a wide range of geological samples. It will be housed and operated in the Department of Geological Sciences at the University of Michigan. The University of Michigan is committed to providing the remaining funds needed to carry out this instrument development project. The instrument will extend existing capabilities for trace element and isotopic analysis and will be applied to research including the dating of microscopic fluid inclusions by the rubidium-strontium radioactive decay method, lutetium-hafnium isotope geochemistry of small samples, transition element geochemistry of terrestrial and extraterrestrial materials, and precise geochronology to determine the production rates of silicic magma. ***

小行星9304159 该奖项提供了质谱仪系统开发所需资金的45%，该系统将联合收割机与等离子体电离和多收集器磁扇区质谱仪相结合。该系统的开发将优化分析性能，包括微分析空间分辨率以及对各种地质样品的微量元素和同位素灵敏度。它将被安置在密歇根大学地质科学系。密歇根大学致力于提供开展这一仪器开发项目所需的剩余资金。 该仪器将扩大现有的微量元素和同位素分析能力，并将用于研究，包括用铷-锶放射性衰变法测定微观流体包裹体的年代、小样本的镥-铪同位素地球化学、地球和地球外物质的过渡元素地球化学以及确定岩浆产出率的精确地质年代学。 ***
