Early Career: Technical support for the University of Rochester LA-ICP-MS and Experimental Geochemistry Laboratories

1545637培训这个地球科学仪器和设施部门资助一名实验室技术人员两年的时间。这名技术人员将负责罗切斯特大学实验岩石学实验室现有激光烧蚀微探头配备电感耦合等离子体质谱仪(LA-ICP-MS)的日常操作，测试和制定用于地球化学研究的玻璃和矿物标准，并协助外部用户操作用于合成相的活塞柱。这一支持与NSFs促进科学进步和促进国家健康、繁荣和福利的使命是一致的，因为这一新职位将培养下一代科学队伍的现代实验和材料分析技术。技术人员将直接支持PI、学生和区域合作者在实验岩石学和地球化学学方面的研究，包括基于古锆石化学分析的地壳分异最早证据，支持环境代理开发的实验运行产品中矿物相之间同位素分馏的基础研究，火山灰矿床辅助相中微量元素分布和价态测定的研究，以评估母岩浆的氧化还原状态，以及支持构造学、变质岩石学研究的微量元素研究，以及作为考古学研究文物来源的指标，仅举几例。

1545637TrailThis Division of Earth Sciences Instrumentation and Facilities Program grant supports a laboratory technician over a two year period. The technician will be responsible for daily operations of an extant laser ablation microprobe equipped inductively coupled plasma mass spectrometer (LA-ICP-MS), testing and developing glass and mineral standards for geochemistry research, and assisting external users with the operation of piston cylinders used to synthesize phases in the experimental petrology lab at the University of Rochester. This support is congruent with NSFs mission of promoting the progress of science and advancing the national health, prosperity and welfare given the importance of training the next generation scientific workforce in modern experimental and materials analysis techniques which this new position will foster.The technician will directly support PI, student and regional collaborator research in experimental petrology and geochemistry including studies of Earth?s earliest evidence of crustal differentiation based on chemical analysis of ancient zircons, fundamental studies of isotope fractionation between mineral phases in experimental run products in support of environmental proxy development, studies of trace element distributions and valence state determinations in accessory phases from ash deposits to assess the redox state of the parent magmas, and trace element investigations in support of studies in tectonics, metamorphic petrology and as indicators of artifact provenance for studies in archeology, to name a few.
