9601952 Zindler This grant, made through the Academic Research Infrastructure (ARI) Program, provides $267,500 as partial support of the costs of acquiring a high- resolution inductively coupled plasma mass spectrometer (HR-ICP-MS) to be housed in the National High Magnetic Field Laboratory (NHMFL) at the Florida State University. This state-of-the- art instrument will allow this group to analyze, with high precision and very low detection limits, the trace elemental and isotopic composition of a great number of elements in the periodic chart in geological samples that are important for a more thorough understanding of the petrogenesis of mantle and crustal materials as well as for a better understanding of the cycling of trace elements in natural waters. Specific studies will include analyses of the Sr, Nd, Pb and Hf isotopic characteristics of mantle-derived ocean island basalts, analyses of the rare earth elemental (REE) and high field strength elemental (HFSE) concentrations in peridotite xenoliths as indicators of the degree of fractionation and partial melting within the mantle and the biogeochemistry of Fe and other biologically important trace metals (i.e. Ni, Cu, Zn, Cd) within the photic zone in the ocean basins and within estuarine sediments. ***

小行星9601952 这项赠款是通过学术研究基础设施（ARI）计划提供的，提供267，500美元作为购买高分辨率电感耦合等离子体质谱仪（HR-ICP-MS）的部分支持，该质谱仪将安装在佛罗里达州立大学的国家高磁场实验室（NHMFL）。 这种最先进的仪器将使该小组能够以高精度和极低的检测限进行分析，地质样品中元素周期表中大量元素的微量元素和同位素组成，对于更深入地了解地幔和地壳物质的岩石成因以及更好地了解微量元素的循环具有重要意义。天然沃茨。 具体研究将包括分析幔源洋岛玄武岩的Sr、Nd、Pb和Hf同位素特征，分析橄榄岩捕虏体中的稀土元素（REE）和高场强元素（HFSE）浓度，作为地幔内分馏和部分熔融程度以及Fe和其他生物重要微量金属的地球化学指标（即Ni、Cu、Zn、Cd）在海洋盆地的透光带和河口沉积物中。 ***
