摘要
用中子活化分析测定了７个南极球粒陨石的主量和微量元素含量，讨论了这些陨石的元素丰度分布特征、南极陨石和非南极陨石的元素丰度差异，并划分了这７个南极陨石的化学群：Ｙ７９１７１７（Ｃ３），Ｙ７４１９３（Ｈ５），ＡＬＨ７６００６（Ｈ６），ＡＬＨ７７２１４（Ｌ３），Ｙ７５２７１（Ｌ５），ＡＬＨ７６００１（Ｌ６），ＡＨ７６００９（Ｌ６）
The major and trace element compositions in the Antarctic meteorite have beendeterminated by Neutron Activation Analysis (NAA). The distribution characteristics of these element abundances were investigated, and the differences of elementabundances between Antarctic and non-Antarctic meteorites were also discussed.All meteorites are classified according to the result of this work and they are as follows: Y791717 (C3), ALH76006 (H6), ALH77214 (L3), Y75271 (LS), ALH76001(L6)and ALH76009(L6).
