UraniumU
- Type
- Sandstone-hosted uranium
Deposit of the low-temperature redox category in the study of uranium ore concentrates (yellowcake) from 40 mines. Uranium precipitated by low-temperature U(VI) to U(IV) reduction below the water table: concentrates richer in 238U (mean 137.887 ± 0.072, 2SD) and 235U/234U scattered by exchange with modern groundwater (Brennecka et al., 2010). Coordinates not given.
