Littleham Cove (Devon)
East Devon (grouped with the Dartmoor area by the authors), United Kingdom
UraniumU, V
- Type
- Uranium-vanadium nodules (metatyuyamunite)
Vein-type uranium ore analysed by Keatley et al. (2021) for δ238U and δ234U (nuclear forensics). Metatyuyamunite with δ234U of -154.6 ‰, the most 234U-depleted of the study, and the largest δ238U shift on acid leaching (+0.17 ‰). Indicative coordinates (Littleham Cove).
