This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). The funds will be used acquire a diode laser heating system for the (U-Th)/He thermochronology laboratory in the Department of Geology of the University of Kansas. The acquisition of a new diode laser heating system will allow (1) continuation of our NSF-sponsored research at KU currently involving many graduate and undergraduate students, (2) countless national and international collaborative efforts, providing a multitude of faculty, researchers, and students access to a state-of-the-art facility, and (3) development of new thermochronometric techniques and exploration of new research avenues. There is a tremendous demand for low-temperature thermochronometry data to address crucial questions about the timing and rates of a wide spectrum of geological processes ranging from tectonics and landscape evolution to energy related research. In addition to our enormous collaborative and service work load, new research avenues in our laboratory as a result of this acquisition will focus among other things on: (1) laser (U-Th)/He dating of carbonate and hydrous phases; (2) diffusion experiments at higher temperatures (900-600ºC), (3) heating and degassing of larger samples (e.g., magnetite), and (4) U-Pb and (U-Th)/He double-dating of zircon and rutile from sedimentary basins. The proposed acquisition will help maintain the current productivity levels, enhance the existing facilities, and impact the national/international user community of our laboratory. The PI and his colleagues also have a long record of integrating research and education, involving graduate and undergraduates in research and attracting minority and underrepresented students to geology and geochemistry.

该奖项根据 2009 年美国复苏和再投资法案（公法 111-5）提供资金，该资金将用于为地质系的 (U-Th)/He 热年代学实验室购买二极管激光加热系统。堪萨斯大学购买新的二极管激光加热系统将允许 (1) 继续在 KU 进行 NSF 资助的研究，目前涉及许多研究生和本科生，(2) 无数的国内和国际合作努力，提供众多教师、研究人员和学生可以使用最先进的设施，以及 (3) 开发新的测温技术和探索新的研究途径 对低温测温数据的巨大需求来解决关键问题。关于从构造和景观演化到能源相关研究的广泛地质过程的时间和速率的问题除了我们巨大的协作和服务工作量之外，由于此次收购，我们实验室的新研究途径将集中在以下方面。其他内容包括：(1) 碳酸盐相和含水相的激光 (U-Th)/He 测年；(2) 较高温度 (900-600°C) 下的扩散实验，(3) 较大样品（例如磁铁矿）的加热和脱气， (4) 对沉积盆地的锆石和金红石进行 U-Pb 和 (U-Th)/He 双重测年 拟议的收购将有助于维持当前的生产力水平，增强现有设施，并影响我们实验室的国家/国际用户社区在整合研究和教育方面也有着悠久的历史，让研究生和本科生参与研究，并吸引少数族裔和代表性不足的学生学习地质学和地球化学。
