Scientific paper

Measurements are given of the Mg isotopic composition in samples of the Allende meteorite. It is shown that some inclusions rich in refractory elements contain Mg of isotopic abundance distinct from normal Mg. Measured Mg isotopic ratios were corrected for mass fractionation by normalizing to the terrestrial (normal) Mg-25/Mg-24. Relative to normal Mg, Allende samples show distinct isotopic anomalies which correspond to enrichment of Mg-24 or Mg-26 of up to 3 per mil or depletion of Mg-25 of up to 1.5 per mil. One sample shows a depletion of Mg-24 or Mg-26 by 1.7 per mil or an enrichment of Mg-25 by 0.85 per mil. These anomalies are smaller by a factor of ten than those found for the oxygen isotopes.
