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.
