POWRE: Re-Os Systematics and Geochronology in Continental Sedimentary Rocks: A Pilot Study in the Morrison Formation

9973359 hannah这笔power拨款将允许PI目前的职业重点发生两个重大变化：(1)从管理和外延到研究，(2)从关注火成岩过程和矿床到沉积环境。在获得终身教职后，她立即开始了近十年的行政工作，这对她的研究效率造成了损害。与霍利·斯坦和约翰·摩根合作，将Re-Os系统学应用于火成岩岩石学和矿石成因问题，这是她的主要支持和连续性来源。在接下来的两年里，她的服务和行政责任将会减少。这项拟议的研究将帮助她利用实验室设施、科学专业知识和实地合作者等优秀资源的优势，开创一条有前途的新研究路线。此外，该项目将使她利用她在高温放射性成因同位素系统学方面的经验和地球化学知识，在沉积环境的地质年代学和元素运输方面开辟新的领域。

9973359HannahThis POWRE grant will permit two significant changes in the PI's current career focus: (1) from administration and outreach to research, and (2) from a focus on igneous processes and ore deposits to sedimentary environments. Almost ten years in administrative positions, beginning immediately after she received tenure, have taken their toll on research productivity. Collaborations with Holly Stein and John Morgan on applications of Re-Os systematics to problems in igneous petrology and ore genesis have been her principal source of support and continuity. Over the next two years, her service and administrative commitments will decline. This proposed research would help her take advantage of an excellent convergence of resources - laboratory facilities, scientific expertise, and field collaborators - to initiate a promising new line of research. Furthermore, the project will let her use her experience in high-temperature radiogenic isotope systematics and knowledge of geochemistry to open new arenas in geochronology and element transport in sedimentary environments.
