Acquisition of a Multi-Collector Thermal Ionization Mass Spectrometer for Darthmouth College

该奖项为达特茅斯学院地球科学系安装和运行的多集热器热电离源质谱仪提供部分（60%）资金。该机构承诺提供收购该仪器所需的剩余资金。该设备主要用于达特茅斯大学地球科学系九名教员的研究和教学项目，他们需要对放射性同位素进行精确测量。他们目前的研究项目包括：(1)矿物风化研究、土壤形成过程和海洋锶演化；(2)森林生态系统中碱离子的循环；(3)土壤和地下水中铅的人为迁移；(4)陆地影响地球化学；(5)花岗岩和变质岩的成因；(6)建立长途候鸟迁徙模式。* * *

9422169 Blum This award provides partial (60%) funding for the acquisition of a multi-collector thermal ionization source mass spectrometer to be installed and operated in the Department of Earth Sciences at Dartmouth College. The institution is committed to providing the remaining funds necessary for this instrument acquisition. The equipment is to be used primarily in the research and teaching programs of nine faculty members in the Department of Earth Sciences at Dartmouth who have a need for accurate measurements of radiogenic isotopes. Their current research projects include: (1) Mineral weathering studies, soil formation processes and marine strontium evolution; (2) Base cation cycling in forest ecosystems; (3) Anthropogenic lead mobility in soil and ground water; (4) Geochemistry of terrestrial impacts; (5) Petrogenesis of granite and metamorphic rocks; and (6) Establishment of migratory patterns for long-distance migrant songbirds. ***
