Abstract
The CO3 carbonaceous chondrite Colony, a 1975 find, was examined by Fe-57 M ossbauer spectroscopy. In agreement with the literature this well-weathered meteorite showed a prominent quadrupole doublet consistent with paramagnet ic Fe3+ phases as well as a doublet for olivine and at least one ferromagne tic sextet. The ratio of Fe3+ to total Fe is consistent with a terrestrial age of 4 x 10(4) years.
