Résumé

The isotopic composition of thallium from six meteorites was measured, in order to determine whether any radiogenic Tl205 from the decay of 24?m.y. Pb205 was present. Although the Pb/Tl ratios of these meteorites differed by factors of 50, isotopic compositions of meteoritic and terrestrial thallium were equal to within 1 per cent. For Canyon Diablo, this implies a solidification time of ?3.0×108 years after nucleogenesis by the ‘sudden synthesis’ model, and ?1.0×108 years after the isolation of the solar system by the ‘continuous synthesis’ model. The bearing of these results on the I129 ? Xe129 ages of Reynolds is discussed.
