UraniumU
- Type
- Sandstone-hosted uranium (authors' classification)
Uranium ore sample from the Queen's University collection analysed by Uvarova et al. (2014) for δ238U and δ234U. Two drill-core uraninites (324-42.5 and AE7) referred to Pankka and Vanhanen (1992), without deposit name. Coordinates not published.
