Comment on ‘Isotopic anomalies of noble gases in meteorites and their origins: 2. Separated minerals from Allende’ by Roy S. Lewis, Jacques Gros, and Edward Anders

O. K. Manuel

Abstract

Correlations between elemental and isotopic ratios of noble gases in mineral separates of Allende are not consistent with the reported identification of a noble gas component trapped in ‘Q’ with 136Xe/132Xe = 0.310 and 20Ne/132/Xe = 10 ± 4. If Q trapped a noble gas component with 136Xe/132Xe = 0.310, then the correlations indicate that there was no Ne in this gas component. If Q trapped a noble gas component with 20Ne/132Xe = 10 ± 4, then the correlations indicate that Q contains no fission Xe.
