Isotopes of the noble gas xenon are generated in the earth by the decay of other radioactive elements. How the different isotopes are distributed is an important clue to the puzzle of how the early Earth formed. In his research commentary, Kaneoka discusses results published in the same issue by [ Kunz et al. ][1] in which precision mass spectrometry was used to analyze samples of mid-ocean ridge basalt to extract various isotope ratios. The findings provide answers to controversial questions… Expand

The Xenon Record of Extinct Radioactivities in the Earth
TLDR
The occurrence of excess radiogenic xenon-129 in well gas suggests that any quantitative degassing of existing solid materials to form the atmosphere must have been limited to a very early period of the earth's history, approximately the first 108 years. Expand
Plutonium-fission xenon found in Earth's mantle
Data from mid-ocean ridge basalt glasses indicate that the short-lived radionuclide plutonium-244 that was present during an early stage of the development of the solar system is responsible forExpand
Xenon in CO2 well gas revisited
We have analyzed the rare gases in a CO2 well gas from Harding County, New Mexico, by mass spectrometry. We have reconfirmed the monoisotopic excess of 129Xe measured previously. The excesses ofExpand
Noble gas state of the ancient mantle as deduced from noble gases in coated diamonds
Cores and coats of five coated diamonds, one from Botswana and four from Zaire, were separately analyzed for their noble gases. Noble gases in the diamonds are essentially of a trapped origin,Expand
