ReinersEAR-0236965 Recent developments in methods and interpretational bases of (U-Th)/He chronometry have demonstrated that this technique poses significant potential for advancing understanding of a wide variety of processes, many of which have been difficult to address with other geochronometric approaches. This project will integrate (U-Th)/He chronometric research in technique development, innovative applications, and undergraduate student research. Work will focus in particular on development of single-crystal He-Pb dating, geomorphologic investigations using ancient coal-fires, tectonic applications that constrain timing, rate, and styles of exhumation and landscape development, and analytical and methodological improvements. To facilitate integration of (U-Th)/He chronometry in undergraduate research, a series of summer workshops for students outside of Yale will be conducted. Students will perform a suite of (U-Th)/He chronometric measurements with modeling and interpretation, over three weeks at Yale, to complement their individual senior theses or other types of projects; faculty mentors will also participate in the latter stages of the workshops. The topical and regional diversity of projects will serve as an introduction to a wide range of research (and the general importance of chronometric constraints) for the students, as well as to test and broaden the range of geologic problems that can be addressed by He dating. This work will facilitate broader impacts in research, learning, and infrastructure by: 1) providing access to, and training and experience in (U-Th)/He chronometry for a wide range of investigators both at Yale and beyond, 2) emphasizing integration of innovative (U-Th)/He chronometric approaches into a wide range of studies besides typical tectonogeomorphic applications, 3) integrating He dating into student research and teaching efforts at Yale, 4) establishing structured annual summer workshops for research by undergraduates and faculty mentors, and helping faculty at primarily undergraduate institutions get plugged-in to analytical facilities for future projects, and 5) creating an opportunity to involve students (including members of underrepresented groups) in a positive research-oriented experience at critical junctures in their educations.

（U-Th）/He测时方法和解释基础的最新发展表明，这种技术对于促进对各种过程的理解具有巨大潜力，其中许多过程是其他地质测时方法难以解决的。该项目将在技术开发、创新应用和本科生研究中整合（U-Th）/He计时研究。工作将特别侧重于发展单晶He-Pb测年法，利用古煤火进行地貌调查，限制挖掘时间、速度和风格以及景观发展的构造应用，以及分析和方法的改进。为了促进（U-Th）/He计时在本科研究中的整合，将为耶鲁大学以外的学生举办一系列夏季研讨会。学生将在耶鲁大学进行为期三周的（U-Th）/He计时测量，并进行建模和解释，以补充他们个人的高级论文或其他类型的项目;教师导师也将参与研讨会的后期阶段。专题和项目的区域多样性将作为一个介绍了广泛的研究（和计时约束的一般重要性）的学生，以及测试和扩大可以解决的地质问题的范围。这项工作将通过以下方式促进对研究、学习和基础设施产生更广泛的影响：1）为耶鲁大学及其他大学的广泛研究人员提供（U-Th）/He计时方法的使用、培训和经验，2）强调将创新的（U-Th）/He计时方法整合到除了典型的构造地貌应用之外的广泛研究中，3）将他约会融入耶鲁大学的学生研究和教学工作，4）为本科生和教师导师的研究建立结构化的年度夏季研讨会，并帮助主要是本科院校的教师为未来的项目插入分析设施，以及5）创造机会，让学生（包括代表性不足的群体的成员）在教育的关键时刻参与积极的研究型体验。
