This award will provide one-half the funds required for the acquisition of a thermal ionization, solid-source mass spectrometer to be installed and operated in the Department of Earth and Planetary Sciences at Washington University, St. Louis. The University is committed to providing the remaining funds that will be needed for the acquisition. The instrument will be used primarily in a research program utilizing state-of-the-art techniques in isotope dilution, uranium- lead geochronology and hafnium isotope measurements in zircons. The scientific purpose of the measurements is to understand the formation of the continents during the evolution of Earth's crust through geologic time.

该奖项将提供所需资金的一半， 获得热电离固体源质谱仪 在地球部安装和操作， 圣路易斯华盛顿大学行星科学系。的 大学致力于提供剩余的资金， 是收购所必需的。 该仪器将主要用于一项研究计划 利用最先进的同位素稀释技术，铀- 锆石中的铅年代学和铪同位素测量。的 测量的科学目的是了解 地壳演化过程中大陆的形成 在地质时代。
