Two standard multivariate statistical computer analyses, i.e. cluster and stepwise discriminant analyses, are applied to classification of antarctic stony meteorites of 1 E chondrite, 11 H chondrites, 14 L chondrites, 4 LL chondrites, 8 C chondrites, 15 achondrites and 1 mesosiderite. Six cases by changing combinations of several variables of magnetic, chemical and petrographical components give basically the same classification of sample grouping, except for a few samples. Also it is worthy of special mention that only two parameters of I_s and I_s(α)/I_s make a good classification of sample grouping.
