This award will permit the acquisition of a multi-collector, inductively coupled plasma mass spectrometer coupled with a laser ablation system (LA-MC-ICPMS) for research, education, and training in Earth, Environmental, and Anthropological Sciences at Washington State University. The instrumentation will be utilized in diverse applications by a team of researchers seeking to address problems across a wide spectrum of scientific disciplines including geochemistry, geochronology, petrology, volcanology, tectonics, fish ecology, archeology, and anthropology. The LA-MC-ICPMS will be housed in the existing ICP-MS laboratory within the GeoAnalytical Laboratory (GAL) in the School of the Environment. This laboratory has not only provided data and research training for students and faculty at WSU, but has also served as an analytical center, supporting the research needs of many outside users. Fundamental research problems to be addressed include chemical evolution of the Earth, geochronology of metamorphic processes, models for mountain belt formation and deformation, salmon migration and life history, and ancient human migration and trade. The instrument will allow improved access to a wide range of isotope systems and methods: zircon Hf isotope geochemistry by LA-MC-ICPMS and solution MC-ICPMS; zircon U-Pb geochronology by LA-ICPMS; whole-rock Hf, Nd, Pb and Sr isotope geochemistry; Lu-Hf and Sm-Nd garnet, lawsonite and apatite geochronology; Sr isotope analysis by LA-MC-ICPMS on minerals, fish otoliths, and archeological artifacts; and laser ablation split stream (LASS) techniques including U-Pb and Hf isotopes in zircon and U-Pb and Nd isotopes in monazite and other accessory minerals.

该奖项将允许购买一台多收集器、电感耦合等离子体质谱仪以及激光烧蚀系统 (LA-MC-ICPMS)，用于华盛顿州立大学地球、环境和人类学科学的研究、教育和培训。 该仪器将被一组研究人员用于多种应用，寻求解决地球化学、地质年代学、岩石学、火山学、构造学、鱼类生态学、考古学和人类学等广泛科学学科的问题。 LA-MC-ICPMS 将安装在环境学院地理分析实验室 (GAL) 内现有的 ICP-MS 实验室中。 该实验室不仅为华盛顿州立大学的学生和教师提供数据和研究培训，而且还充当分析中心，支持许多外部用户的研究需求。需要解决的基础研究问题包括地球的化学演化、变质过程的地质年代学、山带形成和变形模型、鲑鱼迁徙和生活史以及古代人类迁徙和贸易。该仪器将允许改进对各种同位素系统和方法的访问：通过 LA-MC-ICPMS 和溶液 MC-ICPMS 进行的锆石 Hf 同位素地球化学； LA-ICPMS 锆石 U-Pb 地质年代学；全岩 Hf、Nd、Pb 和 Sr 同位素地球化学； Lu-Hf 和 Sm-Nd 石榴石、硬钠石和磷灰石地质年代学；通过 LA-MC-ICPMS 对矿物、鱼耳石和考古文物进行锶同位素分析；激光烧蚀分流 (LASS) 技术，包括锆石中的 U-Pb 和 Hf 同位素以及独居石和其他副矿物中的 U-Pb 和 Nd 同位素。
