Research Technician Support: W. M. Keck Foundation Isotope Laboratory

9629959白色这笔赠款为康奈尔大学W.M.凯克基金会实验室负责操作、维护和监督仪器的一名技术员提供148,179美元作为三年的部分工资支持。该实验室拥有一台用于地质样品痕量元素分析的电感耦合等离子体质谱仪(ICP-MS)，一台用于测定地质和生物样品中放射性元素同位素组成的热电离质谱仪(TIMS)，以及一间用于样品制备的洁净室。这些仪器可满足该小组不同研究的分析需要，包括分析岛弧岩浆和大洋中脊玄武岩的地球化学特征，利用锶和钕的同位素比值作为喜马拉雅山脉沉积物来源和风化史的示踪剂，以及森林生态系统中的生物地球化学循环。***

9629959 White This grant provides $148,179 as three years partial salary support for a technician who will be responsible for operations, maintenance and oversight of instrumentation in the W.M. Keck Foundation Laboratory at Cornell University. This laboratory houses an inductively coupled plasma mass spectrometer (ICP-MS) used for trace element analysis of geological samples, a thermal ionization mass spectrometer (TIMS) used to determine the isotopic composition of radiogenic elements in geological and biological samples and a clean room for sample preparation. These instruments serve the analytical needs of this group's diverse studies including, analyses of the geochemical signatures in island arc magmas and mid-ocean ridge basalts and the use of isotopic ratios of strontium (Sr) and neodymium (Nd) as tracers of both sediment provenance and weathering history of the Himalayas and biogeochemical cycling in forested ecosystems. ***
