摘要：

本文对我国南极陨石的收集、分类和研究工作进行了回顾和阶段性的总结。4次格罗夫山考察共发现陨石样品9834块,其中已完成和计划2008年完成分类的陨石共2431块。在正式公布的684块已分类陨石中,鉴定出2块火星陨石、2块灶神星陨石、6块橄辉无球粒陨石、5块中铁陨石、1块橄榄陨铁、1块铁陨石以及10块碳质球粒陨石等特殊样品,并对其中的部分样品开展了深入的研究。建议拓展南极陨石的收集,持续开展陨石的分类工作,并提出我国南极陨石研究的重点方向。

Abstract:

Ice field exploration,classification and studies of meteorites from Grove Mountains,Antarctica,are reviewed.A total number of 9834 meteorites have been collected during 4 times of the explorations in this region.2431 meteorites out of the collection will be classified by the end of 2008.Of 685 meteorites published in the Meteoritical Bulletin Database,there are 2 martian meteorites,2 eucrites,6 ureilites,5 mesosiderites,1 pallasite,1 iron,and 10 carbonaceous chondrites.Comprehensive studies on these rare types are also summarized in this paper.We suggest continuing Antarctic meteorite searching and classifying projects,and propose key research topics of the Antarctic meteorites.
