Abstract: Analyses on eleven meteorites recovered from the Grove Mountains in Antarctica indicate：all themeteorites have chondritic textures and are identified as ordinary chondrites.In this paper，their petrography and mineralogical chemistry are studied，and their chemical groups-petrologic types are classified，including four Hchondrites，six L chondrites，and one LL chondrites．Especially GRV 020010(LL3)and GRV 021481(H3)are unequilibrated ordinary chondrites，and rare and vacant unequilibrated meteorites in Chinese meteoritic reserves．Moreover，their magnetic susceptibility is measured，and the role of magnetic susceptibility in the classification of chemical groups of meteorites is also discussed tentatively．
