Thermochronology is a vital tool in Earth systems science that allows geoscientists to quantify the thermal evolution of rocks through time. Many geologic processes perturb the temperatures of rocks in the upper crust including the uplift and erosion of mountain belts, hydrothermal fluid flow related to mineral resources, and the burial of rocks in regions that generate hydrocarbons. This project will help establish a new thermochronology laboratory at the University of Illinois at Urbana-Champaign (UIUC), by providing funding for a laboratory technician to oversee the lab?s daily operations. This lab will focus on a particular type of thermochronology?(Uranium-Thorium)/Helium dating?and will be open to visiting researchers and collaborators from other scientific institutions around the country. These visitors will include undergraduate and graduate students who seek to further their training in an important field of geologic study. Despite the prevalence, promise, and demand for the (U-Th)/He dating method, only a handful of labs in the U.S. are currently designed and properly staffed to accept visiting researchers on a regular basis. The funding from this award will therefore allow greater access to a wider pool of (U-Th)/He researchers that seek to advance the technique and its applications.The (U-Th)/He dating method consists of a multiple step process, which the new technician will oversee. He or she will have responsibilities that consist of both training and assisting visitors in target mineral grain selection, preparation, and degassing methods necessary to obtain He measurements, and supervising U, Th, Sm, Ca, and Zr analysis of dissolved aliquots by ICP-MS. These methods require significant time commitments and by joining the UIUC lab, the technician will expand the lab?s research capabilities with increased sample through-put, and allow the lab to host additional PIs with funding to use thermochronology. This grant will allow the (U-Th)/He lab at UIUC to strengthen ongoing and develop new collaborations that include projects focused on: 1) The use of correlations between zircon (U-Th)/He age and effective uranium (eU) to constrain Proterozoic or ?deep-time? thermal histories for orogens and cratons, 2) The development of Fe-oxide (U-Th)/He dating in jasperoids from Carlin-Type Gold Deposits (CTGD) to constrain fluid processes related to ore-formation, and 3) Advancing the zircon (U-Th)/He method by parameterizing the process of radiation damage annealing in zircon. Additional projects with current or future external collaborators where the UIUC lab serves as the main center for (U-Th)/He dating will now be possible with this support.

热团学是地球系统科学中的重要工具，它允许地球科学家可以量化岩石的热演化。许多地质过程都会扰动上皮中岩石的温度，包括山带的隆起和侵蚀，与矿物资源有关的水热流动流以及产生碳氢化合物的地区的岩石埋葬。该项目将在Urbana-Champaign（UIUC）的伊利诺伊大学（UIUC）建立新的热量实验室，通过为实验室技术人员提供资金来监督实验室的日常运营。该实验室将重点关注一种特定类型的热量学？（铀thorium）/氦气约会吗？这些游客将包括在重要的地质研究领域中进一步培训的本科生和研究生。尽管对（U-Th）/HE约会方法的普遍性，承诺和需求，但目前在美国的少数实验室的设计并适当地人员可以定期接受来访研究人员。因此，该奖项的资金将使寻求推进技术及其应用程序的（u-th）/HE约会方法的更广泛的（U-Th）/HE研究人员提供更多的资金。新技术人员将监督该方法。他或她将承担责任，包括培训和协助访客进行目标矿物谷物选择，准备和脱气方法，以获得HE测量，并监督I，TH，TH，SM，CA和ZR分析ICP-MS溶解的等分试样。这些方法需要大量的时间承诺，并加入UIUC实验室，技术人员将通过增加的样品进行扩展实验室的研究能力，并允许实验室托管额外的PI，并借助资金使用热力学。这笔赠款将允许UIUC的（U-Th）/HE LAB加强持续的合作，并开发新的合作，其中包括：1）使用锆石（U-th）/HE年龄和有效的铀（EU）来限制Protorrearogoic或深入的？ thermal histories for orogens and cratons, 2) The development of Fe-oxide (U-Th)/He dating in jasperoids from Carlin-Type Gold Deposits (CTGD) to constrain fluid processes related to ore-formation, and 3) Advancing the zircon (U-Th)/He method by parameterizing the process of radiation damage annealing in zircon.现在，在此支持的情况下，将有可能成为（u-th）/HE约会的主要中心的其他项目。
