MRI: Acquisition of a laser-ablation, multi-collector ICP-MS for research and training in Earth, Environmental, and Anthropological Sciences

该合同将允许华盛顿州立大学购买一台多收集器、电感耦合等离子体质谱仪和激光消融系统(LA-MC-ICPMS)，用于地球、环境和人类学方面的研究、教育和培训。该仪器将由一组研究人员在不同的应用中使用，这些研究人员寻求解决包括地球化学、地质年代学、岩石学、火山学、构造学、鱼类生态学、考古学和人类学在内的广泛科学学科的问题。LA-MC-ICPMS将设在环境学院地球分析实验室(GAL)内现有的电感耦合等离子体质谱仪实验室。该实验室不仅为西澳州立大学的学生和教职员工提供数据和研究培训，而且还作为一个分析中心，支持许多外部用户的研究需求。需要解决的基本研究问题包括地球的化学演化、变质过程的地质年代学、山脉带形成和变形的模式、鲑鱼的迁徙和生活史以及古人类的迁徙和贸易。该仪器将使人们能够更好地获得各种同位素系统和方法：LA-MC-ICPMS和溶液MC-ICPMS的锆石Hf同位素地球化学；LA-ICPMS的锆石U-Pb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、钠钠铝石和磷灰石年代学；LA-MC-ICPMS对矿物、鱼耳石和考古制品的锶同位素分析；以及激光烧蚀裂解流(LASS)技术，包括锆石中的U-Pb和Hf同位素以及独居石和其他辅助矿物中的U-Pb和ND同位素。

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.
