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.

该补助金支持继续学习， 所有南极陨石的天然热释光 在1988/89赛季和随后的赛季。 数据将 提供了陨石坠落的时间 这将提供一种研究冰的新方法 运动过程，特别是这些运动是如何进行的 受横贯南极山脉的影响 数据还将 帮助识别那些经历了不寻常的陨石 历史，如异常轨道或最近的冲击重新加热， 空间，并协助努力确定是否有一个 地球陨石来源的长期变化。 等 这些数据将有助于确保最大的科学回报， 南极陨石收藏。
