Replacement of the Thermal Ionization Mass Spectrometer at Cornell

该奖项提供了38%的资金所需的 获得热电离质谱仪， 在地质科学系安装和运行， 康奈尔大学。大学致力于提供 收购所需的剩余资金。 质谱仪系统将主要用于 主要研究者的研究计划，几个额外的 地质科学系的教师，及其 国家科学基金会支持的研究项目的学生 基金会这些项目采用放射性测年法， 同位素地球化学同位素示踪技术，包括 太古代地壳和地幔的演化等课题， 加拉帕戈斯和马克萨群岛的起源， 海水的组成，以及对安第斯山脉岩浆活动的研究。

This award provides 38% of the funds required for the acquisition of a thermal ionization mass spectrometer to be installed and operated in the Department of Geological Sciences at Cornell University. The University is committed to providing the remaining funds needed for the acquisition. The mass spectrometer system will be primarily used in the research programs of the Principal Investigator, several additional faculty members of the Department of Geological Sciences, and their students in research projects supported by the National Science Foundation. These projects employ the radiometric dating and isotopic tracing techniques of isotope geochemistry and include topics such as the evolution of the Archean crust and the mantle, the origin of the Galapagos and Marquesa islands, the isotopic composition of seawater, and the study of magmatism in the Andes.
