Lead was determined by the isotope dilution technique using a spike of stable lead. The results for two samples give a discordant age pattern generally observed on many young uraninites: Pb-207/Pb-206 age is higher than Pb-206/U-238 age. Pb-207/U-235 age agrees with the Pb-206/U-238 age for three samples. It is concluded that the Pb-206/U-238 age is the most probable and that discordant ages result from uncertainties concerning the original lead.
