Isotopic composition and amounts of xenon extracted from eclogite, from old granite, and from CO_2-well gases have been measured. The Xe content of Bavarian eclogite is close to that of the earth (assumed to be outgassed), and this Xe exhibits no isotope anomalies. Xenon from several old granite samples from the central Transvaal contains substantial amounts of fissionogenic Xe from spontaneous fission of U^(238). Isotopic composition of this Xe is in agreement with values reported by Wetherill… CONTINUE READING
