Differences in the abundances of refractory elements among the various groups of carbonaceous chondrites are reported. Samples of 19 carbonaceous chondrites, including two CI chondrites, nine CM chondrites, five CO chondrites and three CV chondrites, were analyzed for several refractory lithophiles (Ca, Al, Sc, La, Sm), refractory siderophiles (Os, Ir, Ru) and a normalizing element (Mg). The results confirm previous observations of a higher refractory lithophile abundance in CV chondrites than in CI chondrites, and also indicate CM and CO refractory lithophile abundances to be distinctly higher than those of CI chondrites, consistent with formation at different nebular locations. Refractory siderophile abundances are also found to differ among the groups, with the composition of the CI chondrites most nearly resembling that of the sun.
