Tulukuevskoye
Eastern Transbaikalia (Streltsovskoye ore field), Russia
UraniumU
- Type
- Caldera-related volcanic-hosted uranium
A major deposit of the Streltsovskoye ore field, the second largest uranium district in Russia. Uranium occurs in caldera-related Mesozoic volcanic rocks (rhyolites, ignimbrites), as uraninite and coffinite in veins and brecciated zones with quartz, fluorite and carbonate. It is mined as an open pit.
δ238U in ‰ (per mil) Values of the same system
Standard : NBL CRM 112-A
| Value | Range | n | Mineral or matrix | Source |
|---|---|---|---|---|
| −1 / −0.13 ‰ | mineralised rocks (11 samples) High-precision MC-ICP-MS measurements with a 233U-236U double spike (reproducibility ± 0.07 ‰ at 2 standard deviations). Negative δ238U is characteristic of volcanic rocks undergoing oxidative alteration: oxidising fluids preferentially remove 238U, leaving the residual rock lighter. Distinct from the Athabasca (+0.2 ‰) and Olympic Dam (-0.3 ‰). | Golubev et al. 2019, Behavior of the 238U, 235U, and 234U Isotopes at Weathering of Volca… | ||
| −0.59 / −0.22 ‰ | fracture waters (22 samples) Fracture waters in contact with altered uranium minerals. Their δ238U is intermediate between the mineralised rocks (lighter) and the mobilised aqueous phase (heavier, exported downstream). Comparing δ238U and 234U/238U makes it possible to follow the direction of uranium migration. | Golubev et al. 2019, Petrology |
