【摘 要】Lherzolitic shergottites are a small group of martian meteorites, with only six of this group were reported.The first five, i.e. ALHA77005, Y-793605, LEW 88516, GRV99027 and NWA 1950 share similar petrology and geochemistry, probably ejected from a same igneous unit on the Mars [e.g., 1-5]. GRV 020090 was classified as the sixth rock . It may be unique, with a low abundance of olivine and high FeO-contents of Mg, Fe-silicates. In this work, we continue the study of GRV020090, in order to clarify its petrogenesis.
