Isotope dilution analyses for fissiogenic ruthenium and molybdenum in samples from Oklo reactor zone 9 and in rocks from the periphery show pronounced fractionation between ruthenium, technetium, and molybdenum. The fractionation patterns demonstrate that neither the depletion nor the enhancement of these three elements could have been solely controlled by changes in the electrochemical environment.
