This award, which is jointly funded with NASA, supports the systematic measurement of the natural thermoluminescence levels in suitable Antarctic meteorites. Since natural thermoluminescence is a function of radiation and thermal history, its measurement enables partial assessment of questions relating to the origin of the meteorites and how to choose significant meteorites for detailed study. Some of the meteorites to be studied have experienced minimal exposure to cosmic rays (those that are undersaturated with 26Al) and thus are extremely interesting. This project is designed to help clarify natural thermoluminescence production systematics and to improve interpretation of the results of geochemical analyses of meteorites.

该奖项是与NASA共同资助的，支持对合适的南极陨石中的自然热释光水平进行系统测量。由于自然热释光是辐射和热历史的函数，其测量使得能够部分地评估与陨石的来源以及如何选择重要的陨石进行详细研究有关的问题。一些将要研究的陨石经历了极少的宇宙射线暴露(那些未饱和的26Al)，因此非常有趣。该项目旨在帮助澄清天然热释光产生系统，并改进对陨石的地球化学分析结果的解释。
