英文摘要We have determined the concentrations of Be-10 and Al-26 in GRV 99027 recovered by the 16th Chinese Antarctic expedition team, which are 14.1 +/- 0.6 dpm/kg and 67.5 +/- 3.4 dpm/kg, respectively. From the concentration of Be-10, we calculate a cosmic-ray exposure age of 4.4 +/- 0.6 Ma for GRV 99027. The concentration of Al-26 is too high compared to the Be-10 exposure age, indicating extra production from solar ray. The exposure ages, petrologic and geochemical characteristics of mantle-derived Martian meteorites GRV 99027, LEW 88516, Y-793605, NWA 1950 and ALHA77005 are very similar, suggesting that these meteorites most probably were ejected from Mars in the same impact event.
