Abstract:

Petrography, mineral chemistry and classification of 32 meteorites collected by the 15 th and 16 th Chinese Antarctic Research Expeditions (CHINARE) were summarized. These meteorites include 23 equilibrated ordinary chondrites, 6 unequilibrated ordinary chondrites, 1 Martian lherzolite, 1 eucrite, and 1 ungrouped iron meteorite. Possible meteorite concentrating mechanisms in Grove Mountains area, unusually low cosmic ray explosion age of GRV 98004 (H5), and ejection ages of Martian meteorites are discussed. In addition, several aspects in the future study of Grove Mountains meteorites are proposed.
