Oklo: natural fission reactor program. Progress report, January 1-March 31, 1980
- comp.
The techniques to measure lead isotopic abundances in geologic material have been refined and tested with National Bureau of Standards lead isotope standards. The results from 28 analyses show that our measurements of /sup 207/Pb//sup 206/Pb and /sup 208/Pb//sup 206/Pb ratios are both reproducible and accurate. However, our data for the /sup 204/Pb//sup 206/Pb ratio indicate that our mass 204 background correction may be causing problems. The initial work to measure gadolinium isotopic abundances has been accomplished. Studies of rubidium and strontium isotopic ratios in the Oklo reactor zone 2 and adjacent areas indicate that fissiogenic rubidium and strontium are observed in solution when the samples adjacent to the reactor zone are leached for 20 minutes with 0.5 N HCl, while fissiogenic rubidium and strontium are observed in the insoluble residues of samples from reactor zone 2 that are leached in the same manner. Additional work will be done to see if some quantitative conclusions about rubidium and strontium transport at the Oklo site can be deduced.
