摘　　要：We report the petrography, mineral chemistry and oxygen isotopic composition of GRV 99027, a new Mar-tian meteorite recently collected during the 16th Chinese Antarctic Research Expedition. This meteorite consists of two textural regions. The interstitial region is characterized by the presence of plagioclase and phosphate, and higher FeO contents of olivine and orthopyroxene, in comparison with the poikilitic region. All of the observations are similar to the three known Martian lherzolites. We classify GRV 99027 as the fourth sample of Martian lherzolite.We report the petrography, mineral chemistry and oxygen isotopic composition of GRV 99027, a new Mar-tian meteorite recently collected during the 16th Chinese Antarctic Research Expedition.
