【摘要】我国经过五次南极格罗夫山科学考察后,从南极格罗夫山地区回收到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。我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年期间开展了四次陨石分类工作,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。

【Abstract】 China has recovered 11452 meteorites from Grove Mountains of Antarctica after 5 explorations. It is a tough work to determine the chemical groups and petrography types. Traditional chemical classification of meteorites is destructive and needs a lot of time to prepare the sections, but also needs a mount of financial funds and human work to finish the fundamental classifications. So some researchers attempt to establish the magnetic susceptibility classification of meteorites, which is un-destructive and efficient. About 2300 ordinary chondrites recovered from Grove Mountain, Antarctica, have been classified under the organization of resource-sharing platform of polar samples and funded by Ministry of Science and Technology of the People’s Republic of China during 2003-2008. This paper will comparatively study the magnetic susceptibility and chemical classifications of the upper meteorites and assess its application in the future.
