格羅夫山普通球粒隕石的磁化率和化學分類方法對比分析
[Abstract]:After five scientific expeditions to the Grove Mountains, China recovered 11,452 meteorite samples from this area. Antarctic meteorites are faced with a great deal of basic classification work after recovery and need to determine their chemical groups and rock types. Because the traditional chemical classification method is not only harmful to samples, but also time-consuming and energy-consuming, it needs a lot of financial and manpower support to complete the basic classification of meteorites. Therefore, the use of fast, non-destructive susceptibility classification to determine meteorite types is also being explored internationally. The basic classification of meteorites in China was funded by the sample sharing platform of the Ministry of Science and Technology. During 2003 and 2006-2008, the classification of meteorites was carried out four times, and more than 2,300 chemical groups and rock types of ordinary chondrites were determined. Impact strength and weathering degree. On the basis of basic classification work, this paper discusses the results of magnetic susceptibility analysis of these samples, and gives the applicable scope and application prospect of magnetic susceptibility classification.
