Sixty four chondrites (14 H, 25L, 17LL and 8C), 32 achondrites and 2 rare stony-iron meteorites from Antarctica were analyzed by the standard wet chemical analysis method. Analyses are reported for all but the achondrites, with those analyses being published elsewhere. Analyses of fresh and weathered parts of three chondrites indicate that abundances of most major elements are essentially the same between the two parts except for the proportions of Fe, FeO and Fe2O3. H chondrites and L and LL chondrites are distinct in several components (e.g. Na2O is separated at 0.85 wt percent). When iron and FeS are subtracted, all the ordinary chondrites have essentially the same composition. The composition of the eight carbonaceous chondrites indicate that they comprise both C2 and C3 types in equal number; they are distinctly lower in SiO2, Na2O and K2O and higher in MgO, A12O3 and CaO than the ordinary chondrites. The stony-iron meteorites analyzed are similar to lodranite.
