Natural Thermoluminescence Levels in Antarctic Meteorites and Related Studies

这笔赠款支持继续研究1988/ 1989年和以后的实地季节返回的所有南极陨石的自然热释光水平。这些数据将提供有关陨石落在冰盖中的时间的信息，这将提供一种研究冰运动过程的新方法，特别是这些运动如何受到横跨南极的山脉的影响。这些数据还将有助于识别那些经历过不寻常历史的陨石，比如异常轨道或最近太空中的冲击再加热，并有助于确定这些陨石的来源是否存在长期变化。这些数据将有助于确保从南极陨石收集中获得最大的科学回报。

This grant supports the continuation of studies of the level of natural thermoluminescence in all Antarctic meteorites returned during the 1988/89 and subsequent field seasons. The data will provide information concerning the time the meteorites have laid in the ice sheet, which will afford a novel means of studying ice movement processes, and, in particular, how these movements are affected by the trans-Antarctic mountains. The data will also help identify meteorites which have experienced unusual histories, such as anomalous orbits or recent shock reheating in space, and assist efforts to determine whether there has been a secular variation in the source of the meteorites to earth. Such data will help ensure the maximum scientific return from the Antarctic meteorite collection.
