Continental 1
Wyoming, United States
UraniumU
- Type
- Sandstone-hosted roll-front uranium
Roll-front mineralisation in porous sediments, starting with the Laramide uplift and peaking in the Oligocene; young uraninite, poor in lead and REE. Uraninite 87Sr/86Sr measured by Balboni et al. (2016) for nuclear forensics: low ratios (below 0.7200) in low-temperature sandstone deposits, high in pegmatites, veins and breccia pipes. Coordinates not given.
87Sr/86Sr isotope ratio, no unit Values of the same system
Standard : NIST SRM 987
