Technician Support: Arizona Radiogenic Helium Dating Lab and HR-ICP-MS Lab

这笔赠款为亚利桑那大学地球科学(U-Th)/He测年和部门电感耦合等离子体质谱仪实验室的全职实验室经理/技术员提供部分支持。实验室经理支持两个实验室的用户培训、样品处理、设备维护以及规划和设计。(U-Th)/He测年法(He测年法)在过去十年中得到了极大的发展，现在是许多区域构造和地貌研究的主要内容，要求对浅层地壳挖掘的时间和速度加以限制。美国大学的He约会实验室支持各种项目和研讨会的培训和分析，这些项目和研讨会涉及外部和内部PI、本科生和研究生、博士后和教职员工。该实验室进行构造和地貌应用研究，以及He测年的实验开发和创新应用研究。它进行了必要的实验，以测年和解释未探索的相的年龄，改进的分析方法，并将He测年应用于一系列新的问题，如地表野火、碎屑研究和陨石热史。所有这些项目都需要实验室经理/技术人员的支持，以进行用户培训、样品处理和仪器维护。除了支持内部和外部用户的测年业务外，这里提议的技术人员支助还将为亚利桑那大学内部和外部的广泛用户提供常规高分辨率(部门)电感耦合等离子体质谱仪分析和培训。

0732380ReinersThis grant provides partial support for a full time lab manager/technician for the (U-Th)/He dating and sector ICP-MS labs in Geosciences at the University of Arizona. The lab manager supports user training, sample processing, equipment maintenance, and planning and design in both labs. (U-Th)/He chronometry (He dating) has expanded dramatically in the last decade and is now a staple of many regional tectonic and geomorphologic studies requiring constraints on the timing and rate of shallow-crustal exhumation. The He dating lab at the UofA supports training and analyses for diverse projects and workshops involving both external and internal PIs, undergraduate and graduate students, postdocs, and faculty. The lab conducts research in tectonic and geomorphic applications and experimental development and innovative applications of He dating. It performs experiments necessary for dating and interpreting He ages of unexplored phases, improved analytical methods, and applying He dating to a range of novel problems such as surface wildfire, detrital studies, and meteorite thermal histories. All of these projects require support from the lab manager/technician for user training, sample processing, and instrument maintenance. In addition to supporting He dating operations for both internal and external users, the technician support proposed here will provide for routine high-resolution (sector) ICP-MS analyses and training to a broad spectrum of users internal and external to the University of Arizona.
