Carbon Isotope Abundance in Meteoritic Carbonates

Robert N. Clayton 1

1 Enrico Fermi Institute for Nuclear Studies, University of Chicago, Chicago 37, Illinois

The C13/C12 ratio in the carbonate minerals of Orgueil, a carbonaceous chondrite, is 6 percent greater than the ratio in any known terrestrial carbon. The effect may be produced by a chemical isotope fractionation involving processes not common on earth, or it may be the result of incomplete homogenization of substances with different histories of nucleosynthesis.
