- Unconformity-related uranium
Unconformity-related uranium deposit in the northwest of the Athabasca basin, studied for internal variation of the 238U/235U ratio.

| −0.295 / 0.295 ‰ | uraninite and pitchblende A high-precision study of 50 samples, with a long-term reproducibility of ± 0.07 ‰. Shea Creek shows an internal variation of 0.59 ‰ (0.295 ‰ half-range around the mean), one of the largest in the study. It reflects local redox conditions and the timing of the passing mineralisation front. | Uvarova et al. 2014, 238U/235U isotope ratio variations in minerals from hydrothermal ura… |
