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

1545637 TrailThis地球科学仪器和设施计划拨款部门支持实验室技术人员超过两年。 该技术员将负责现有的配备激光烧蚀微探针的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在罗切斯特大学实验岩石学实验室合成相的活塞缸。 这一支持与NSF的使命是一致的，即促进科学进步，促进国家健康，繁荣和福利，因为培养下一代科学工作者掌握现代实验和材料分析技术的重要性，这一新职位将促进。基于古锆石化学分析的地壳分异的最早证据，支持环境代用发展的实验产品中矿物相之间同位素分馏的基础研究，来自火山灰沉积物的微量元素分布和副相中价态测定的研究，以评估母岩浆的氧化还原状态，以及支持构造研究的微量元素调查，变质岩石学和作为文物来源的考古学研究的指标，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.
