New Mexico, Grants district (Laguna reservation), United States
UraniumU
- Type
- Tabular sandstone-hosted uranium
Ore from the Smithsonian Institution collection (Cowan and Adler, 1976 suite) analysed by Bopp et al. (2009); δ238U relative to IRMM REIMP-18A. Tabular sandstone deposit with δ238U of +0.38 ‰, about 1 ‰ above magmatic ores: fractionation during low-temperature U(VI) to U(IV) reduction (nuclear field shift). Indicative coordinates.
