Terrestrial Age Measurement of Antarctic Meteorites

该奖项支持使用氯-36测量南极陨石的地球年龄。这项工作将与正在进行的关于地外物质中的宇宙成因核素和陆地表层岩石暴露历史的研究相结合。这些地球年龄不仅提供了关于南极陨石的重要信息，也提供了关于南极冰川学和地质学的重要信息。这些研究涉及陨石的流入速度、冰盖的历史以及陨石的配对。还将尝试开发钙-41陆地年龄方法。

This award supports the measurement of the terrestrial ages of Antarctic meteorites using chlorine-36. The work will interface with ongoing studies of cosmogenic nuclides in extraterrestrial materials and of the exposure history of terrestrial surface rocks. These terrestrial ages give vital information not only on Antarctic meteorites, but also on Antarctic glaciology and geology. The studies involve the influx rate of meteorites, the history of ice sheets, and the pairing of meteorites. Development of the calcium-41 terrestrial age method will also be attempted.
