Abstract

: The Moon is a key target for long-term human exploration beyond the Earth. In addition to precious lunar returned samples, lunar meteorites can provide important supplementary information on the composition and evolutionary history of the Moon. Herein, we report the elemental compositions of two lunar meteorites, Northwest Africa (NWA) 4734 and NWA 11111, analyzed using instrumental neutron activation analysis (INAA). Reference materials, including SRM2703 and GWB07105, were used for quality control. The INAA results for most elements in NWA 4734 and NWA 11111 are consistent with the previously reported data obtained by inductively coupled plasma-mass spectrometry analysis within analytical uncertainties. Since the INAA analysis is non-destructive, it can be widely applied to trace element measurements for extraterrestrial samples.

用仪器中子活化分析法测定月球陨石的多元素组成

：月球是人类在地球以外进行长期探索的关键目标。除了珍贵的月球返回样本外，月球陨石还可以提供有关月球组成和演化历史的重要补充信息。在此，我们报道了两颗月球陨石，西北非洲（NWA）4734和NWA 11111的元素组成，并使用仪器中子活化分析（INAA）进行了分析。标准物质，包括SRM2703和GWB07105，用于质量控制。NWA 4734和NWA 11111中大多数元素的INAA结果与之前报道的在分析不确定性范围内通过电感耦合等离子体质谱分析获得的数据一致。由于INAA分析是非破坏性的，它可以广泛应用于地外样品的微量元素测量。
