| Abstract: | Re-examination of all known xenon isotopic data for the carbonaceous chondrites Renazzo, Mokoia, and Groznaya reveals that these meteorites contain (26±7), (33±1), and (36±4)·10–12 (ccSTP136fXe/g) of244Pu fission xenon, respectively. These meteorites started to retain their xenon more than 4,800 million years ago at about the same time as did the carbonaceous chondrites Allende, Murray, and Murchison. |
