Scientific paper

The xenon isotopic composition measured in samples from various origins shows that variations relative to the atmospheric standard are common. Excesses in 129Xe and fissiogenic xenon, derived from the extinct radioactivities 129I and 244Pu respectively, are characteristic of mid-ocean ridge basalts, whereas 238U-fission xenon excesses are only found in granitoid samples or in samples which are contaminated by the continental crust. Hence, the xenon isotopes can be used as tracers in geodynamics. A model for the degassing of the terrestrial mantle is developed and reflections on the time interval between the formation of meteorites and the formation of the Earth are made.
