中国经过5次南极格罗夫山科学考察后，从该地区回收到11452块陨石样品。南极陨石回收后面临着庞大的基础分类工作，需要确定其化学群和岩石类型。由于传统的化学分类方法不仅有损样品，而且样品制备耗时耗力，需要大量的经费和人力支持才能完成陨石的基础分类工作。因而国际上也在探索使用快速、无损的磁化率分类方法来确定陨石的类型。中国陨石基础分类工作得到科技部样品共享平台的资助，在2003年和2006-2008年期间开展了4次陨石分类工作，共确定了2300多块普通球粒陨石的化学群、岩石类型、冲击强度和风化程度。本文在基础分类工作的基础上，探讨这些样品的磁化率分析结果，并给出磁化率分类的适用范围及应用前景。

China has recovered 11 452 meteorites from the Grove Mountains of Antarctica during five explorations of the region .The determination of chemical groups and petrography types in the meteorites is difficult .Traditional chemi-cal classification methods for meteorites are destructive and require a lot of time for section preparation , but they al-so need substantial financial and human resources to complete fundamental classifications .Therefore, some re-searchers have attempted to establish a magnetic susceptibility classification technique for the meteorites that is non -destructive and efficient .Between 2003 and 2008, about 2 300 ordinary chondrites recovered from the Grove Mountains in Antarctica were classified by the resource-sharing platform responsible for polar samples and funded by the Ministry of Science and Technology of the People ’ s Republic of China .This paper comparatively studies the magnetic susceptibility and chemical classification methods of the upper meteorites to assess the suitability of their future application .
