摘要：

中国南极考察队于 1 998～ 2 0 0 0年两次对东南极格罗夫山地区进行了陨石回收工作 ,共回收 32块陨石 ,根据 1 5、1 6次队回收的陨石的分布范围、密度和岩石化学类型的差异性 ,初步确定格罗夫山阵风悬崖一带是一个新的陨石富集区。

Abstract:

Chinese Antarctic Scientific Expedition (CHINARE) has been to the Grove Mountains, East Antarctica twice from 1998 to 2000. Meteorites search and collection was one of its major missions. A total of 32 samples were recovered. On the basis of the distribution area, density as well as the diversity of the petrographic, mineralogic and chemical characteristics, we regard the Escarpment zone in the Grove Mountains as a new meteorites enrichment area.
