项目摘要

This award will provide funds to purchase a current-generation X-ray fluorescence (XRF) spectrometer in the GeoAnalytical laboratory at Washington State University, in order to continue to provide a reliable chemical analysis service to the geoscience community. The WSU GeoAnalytical Laboratory is considered an important component of academic geoscience research and research training in North America through the analytical services it provides, most notably for the research community studying volcanic processes. Basic research in this field underpins applications to natural hazards. The XRF facility at WSU is employed in a broad range of geological, environmental science, and archaeological research. Chemical composition is a necessary part of the description of igneous rocks, gives fundamental information about weathering and sedimentary processes, and is growing in application to geoarchaeology. Projects that use data from the instrument include studies of super-eruptions from calderas and large igneous provinces. Additionally, chemical analysis of Earth surface materials such as sediments, paleosols and archaeological materials feeds the knowledge base for global change science, including past human impacts on the environment. Ensuring a steady supply of trained geochemists and skilled technicians into the national workforce is therefore essential to the future health of society.

该奖项将提供资金在华盛顿州立大学地理分析实验室购买当前一代的 X 射线荧光 (XRF) 光谱仪，以便继续为地球科学界提供可靠的化学分析服务。华盛顿州立大学地球分析实验室通过其提供的分析服务，尤其是为研究火山过程的研究界，被认为是北美学术地球科学研究和研究培训的重要组成部分。该领域的基础研究支撑着自然灾害的应用。华盛顿州立大学的 XRF 设施广泛用于地质、环境科学和考古研究。化学成分是描述火成岩的必要组成部分，提供有关风化和沉积过程的基本信息，并且在地质考古学中的应用不断增长。使用该仪器数据的项目包括对火山口和大型火成岩省的超级喷发的研究。此外，对沉积物、古土壤和考古材料等地球表面材料的化学分析为全球变化科学（包括过去人类对环境的影响）提供了知识库。因此，确保国家劳动力队伍中稳定供应训练有素的地球化学家和熟练的技术人员对于社会未来的健康至关重要。
