项目摘要
An increase in understanding of how the Earth system operates in the present, and how it has evolved over billions of years, has led geoscientists to ask ever more precise questions about the timescales of geologic processes and the feedbacks between the ocean-atmosphere system, the biosphere, and the solid Earth. In order to provide quantitative answers to these questions, high-precision time constraints are required. Radiometric dating, or geochronology, is the most reliable way to provide such time constraints, and U-Pb geochronology is the most versatile method available. In order to meet the growing demand for geochronologic data in the Geosciences, this grant provides technical support for the U-Pb geochronology lab in the Department of Geosciences at Princeton University. This will create a new position that will: 1) increase the lab's capacity to take on new projects and host additional external scientists, including faculty and graduate and undergraduates students; 2) maintain efficient operations of clean lab facilities and analytical equipment; 3) streamline knowledge transfer between incoming and outgoing graduate students and postdocs; 4) provide a more reliable means for method development and improvement of precision and accuracy in U-Pb geochronology; 5) improve the integration of laboratory research into undergraduate and graduate curriculum; and 6) assist in outreach efforts to bring the lab?s science to a broader community. Given the unquenchable thirst in the Geosciences for geochronology, additional technical support will help the Princeton lab do its part to fill the deficit between user demand and capacity of existing geochronology labs.This grant provides much-needed technical support within the U-Pb geochronology laboratory in the Department of Geosciences at Princeton University. U-Pb geochronology is the most broadly applied system for determining the rates of geologic processes, and current demand for high-precision ID-TIMS U-Pb dates far outweighs the capacity of geochronology labs to generate them. The U-Pb lab at Princeton University, overseen by PI Schoene, wishes to expand its operations in order to host more outside users and devote more time to technique development that is required to place high-precision U-Pb dates into petrologic and/or stratigraphic context. Research themes within Schoene's lab range from understanding the evolution of continents and volcanic systems, calibrating rates of climate and biologic change in the deep past through ashbed zircon geochronology of stratigraphic sections, measuring the flux of flood basalt eruptions and understanding their environmental impact, and increasing the precision and accuracy of geochronology of Lunar samples. Each of these topics includes externally-funded collaborators from outside of Princeton University that send students to carry out the work. The new technical support will expand the ability of the lab to train both internal and external users and, in conjunction with upcoming facilities expansion, will provide new opportunities for integration of TIMS and laser ablation ICPMS U-Pb geochronology. These efforts serve both the need for assessing and increasing the accuracy of resulting ages and how to interpret them as chronometers of a wide range of geologic processes.
随着对地球系统目前如何运行以及数十亿年来它是如何演变的了解的增加,地球科学家们对地质过程的时间尺度以及海洋-大气系统、生物圈和固体地球之间的反馈提出了越来越精确的问题。为了对这些问题提供定量的答案,需要高精度的时间约束。放射性测年法或地质年代学是提供这种时间限制的最可靠的方法,而U-Pb地质年代学是最通用的方法。为了满足地球科学领域对地质年代学数据日益增长的需求,本基金为普林斯顿大学地球科学系U-Pb地质年代学实验室提供技术支持。这将创造一个新的职位,它将:1)增加实验室承担新项目的能力,并接待更多的外部科学家,包括教师、研究生和本科生;2)保持洁净实验室设施和分析设备的高效运行;3)简化研究生和博士后之间的知识转移;4)为U-Pb年代学方法的开发和精密度、准确度的提高提供了更为可靠的手段;5)提高实验室研究与本科和研究生课程的整合;并协助外联工作以引进实验室?将科学推广到更广泛的社区。鉴于地球科学对地质年代学的不可抑制的渴望,额外的技术支持将帮助普林斯顿实验室尽其所能,填补用户需求与现有地质年代学实验室能力之间的缺口。这笔拨款为普林斯顿大学地球科学系U-Pb地质年代学实验室提供了急需的技术支持。U-Pb年代学是用于确定地质过程速率的最广泛应用的系统,目前对高精度ID-TIMS U-Pb年代学的需求远远超过了地质年代学实验室的能力。由PI Schoene管理的普林斯顿大学U-Pb实验室希望扩大其业务范围,以容纳更多的外部用户,并将更多的时间投入到技术开发中,以便将高精度的U-Pb日期置于岩石学和/或地层环境中。Schoene实验室的研究主题包括了解大陆和火山系统的演化,通过地层剖面的灰床锆石年代学校准过去深层气候和生物变化的速率,测量洪水玄武岩喷发的通量并了解其对环境的影响,以及提高月球样品年代学的精度和准确性。每一个主题都包括普林斯顿大学以外的外部资助的合作者,他们派学生去完成这项工作。新的技术支持将扩大实验室培训内部和外部用户的能力,并与即将到来的设施扩建相结合,将为TIMS和激光烧蚀ICPMS U-Pb地质年代学的整合提供新的机会。这些努力既满足了评估和提高所得年龄的准确性的需要,也满足了如何将它们解释为各种地质过程的计时器的需要。
