Technician Support: UCLA 40 Ar/39 Ar Dating Facility, Phase II

这项拨款为加州大学洛杉矶分校40Ar/39Ar实验室的技术监督提供了部分工资支持（第二阶段），由经理Marty Grove博士负责。这项支持是在三年的“第一阶段”（EAR-9627980）相同水平的资助之后提供的。在过去十年中，40Ar/39Ar分析需求的爆炸性增长证明了这种直接设施支持是合理的，这既反映了测年技术的成熟，也反映了人们对其在热年代学和火山地层学领域独特贡献的认识。40Ar/39Ar实验室通过鼓励广泛的地质学家直接参与其样品的分析项目，并通过培训委托这些新实验室的许多科学家，在这一增长中发挥了重要作用。自1991年以来，该实验室被来自51个不同机构的84名科学家使用，产生了70多篇论文，并为16篇研究生论文做出了重大贡献。这些与访问科学家的互动都增加了一个不断增长的数据库，从中可以预测不同地质环境中矿物系统的反应，并鼓励在解释模型迅速发展的这一时期传播思想。在第一阶段的资助下，格罗夫博士开发了一种自动提取系统它与质谱法完全集成。该职位的持续资助将使该小组在造山作用和地貌演化的构造研究中保持最高的生产力，并将通过培训具有40Ar/39Ar热年代学最先进技术的访问科学家，继续使更广泛的社区受益

9909584HarrisonThis grant provides a continuation (Phase II) of partial salary support for technical oversight of the UCLA 40Ar/39Ar lab by manager, Dr. Marty Grove. This support follows three years of 'Phase I' (EAR-9627980) funding at the same level. Direct facility support of this kind is justified by the explosive growth in the demand for 40Ar/39Ar analyses over the last decade, reflecting both the maturity of the dating technique and the recognition of its unique contribution in the realms of thermochronology and volcanic stratigraphy. This 40Ar/39Ar laboratory has played a significant role in this growth by encouraging a broad spectrum of geologists to participate directly in analysis programs of their samples and by training many of the scientists that have commissioned these new laboratories. Since 1991, the lab was utilized by 84 scientists from 51 different institutions resulting in the production of over 70 papers and significantly contributing to 16 graduate dissertations. These interactions with visiting scientists both added to a growing data base from which to anticipate the response of mineral systems in differing geological environments and encourage the transmission of ideas during this period when interpretive models are rapidly evolving. Under Phase I funding, Dr. Grove developed an automated extraction system which is fully integrated with the mass spectrometry. Continued funding of this position will allow this group to remain at their most productive in tectonic studies of orogenesis and landform evolution and will continue to benefit a broader community through training of visiting scientists with state-of-the-art techniques in 40Ar/39Ar thermochronology.***
