项目摘要
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.
热年代学是地球系统科学中的一个重要工具,它使地球科学家能够量化岩石随时间的热演化。许多地质作用扰动了上地壳岩石的温度,包括山脉的隆起和侵蚀、与矿产资源有关的热液流动以及产生碳氢化合物的地区岩石的埋藏。该项目将帮助建立一个新的热年代学实验室在伊利诺伊大学厄巴纳-香槟分校(UIUC),通过提供资金的实验室技术人员监督实验室?的日常运营。这个实验将集中在一个特殊类型的热年代学?(铀-钍)/氦定年?并将向来自全国其他科学机构的访问研究人员和合作者开放。这些参观者将包括本科生和研究生,他们寻求在地质研究的一个重要领域进一步培训。尽管(U-Th)/He测年方法的流行,承诺和需求,但美国目前只有少数实验室被设计并配备适当的人员定期接受访问研究人员。因此,该奖项的资助将使更多的(U-Th)/He研究人员能够寻求推进该技术及其应用。(U-Th)/He测年方法由多个步骤组成,新技术人员将监督该过程。他或她将有责任,包括培训和协助游客在目标矿物颗粒的选择,准备和脱气方法,以获得必要的He测量,并监督U,Th,Sm,Ca和Zr的溶解等分试样的ICP-MS分析。的研究能力,增加样品吞吐量,并允许实验室托管额外的PI与资金使用热年代学。这笔赠款将使(U-Th)/He实验室在UIUC加强正在进行的和发展新的合作,包括项目集中在:1)使用锆石(U-Th)/He年龄和有效铀(eU)之间的相关性,以限制元古代或?深度时间(2)卡林型金矿床(CTGD)中碧玉类矿物的Fe-氧化物(U-Th)/He定年方法的发展,以制约与成矿有关的流体过程;(3)通过参数化锆石的辐射损伤退火过程,改进了锆石(U-Th)/He定年方法。与当前或未来的外部合作者的其他项目,其中UIUC实验室作为(U-Th)/He测年的主要中心,现在将有可能与此支持。
