Abstract
Comparison between 129I-radiogenic 129Xe and 244Pu-fissiogenic 136Xe components in terrestrial xenon suggests that the Earth's inner region accreted a few tens of millions of years earlier than the outer region from which the atmosphere evolved. The results also indicate that there has been no substantial mixing of the two regions since the Earth's accretion.
