The Neoproterozoic Throssell Range Group, Western Australia: A Peri‐Marginal Continental Basin in Rodinia and Its Implications for the Centralian Superbasin

Basin Research, Volume 38, Issue 1, January–February 2026.
This study of recent exploration drillcore reveals two sequences separated by a disconformity. Basal alluvial fan to shallow marine lithofacies suggest reactivation of basement faults, and a distinct upwelling signature points to a flooded margin, controlled by differential subsidence of diverse Proterozoic lithosphere.

Sedimentary Environment, Tectonic Setting, and Uranium Mineralization Implications of the Yimin Formation, Kelulun Depression, Hailar Basin, China

Journal of Marine Science and Engineering
The sandstone-type uranium deposit of the Kelulun Depression is the first industrially valuable uranium deposit discovered in the Hailar Basin. This study performed a systematic examination of 17 sandstone samples from the Yimin Formation in the Kelulun ...

Localized and Transient Oxygenation of Shallow Oceans of Southwestern Laurentia at the Ediacaran–Cambrian Boundary

Geobiology, Volume 24, Issue 1, January/February 2026.
ABSTRACT The Ediacaran–Cambrian boundary, which precedes one of the most significant biotic diversification events in Earth's history, is associated with a global negative carbon isotope excursion termed the BAsal Cambrian carbon isotope Excursion (BACE).

Nanoscale relationships between uranium and carbonaceous material in alteration halos around unconformity-related uranium deposits of the Kiggavik camp, Paleoproterozoic Thelon Basin, Nunavut, Canada [PDF]

, 2016
International audienceConcentrations of 7% U and 1% Cu were identified in massive, brecciated, and amorphous carbonaceous materials (CM) characterized by strongly negative values of carbon stable isotopes (δ13C = − 39.1‰ relative to PDB).

Restoring the Missing Late Cretaceous Arc of Iran

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract Persistent arc magmatism archives fluid transport and mantle partial melting in subduction zones. However, arc magmatism often exhibits different magmatic records along the strike, as seen in the Tethyan orogenic belt. During Neo‐Tethys subduction under Iran, there was pulsed arc magmatism with Middle Jurassic and Eocene magmatic flare‐ups ...

The Cenomanian–Turonian boundary interval in the Western Canada Foreland Basin: Stratigraphy, geochemistry, geochronology and sea‐level changes recorded in expanded and condensed clastic successions

The Depositional Record, Volume 11, Issue 5, Page 1200-1258, November 2025.
Shallow‐marine mudstone of the Cretaceous Kaskapau Formation in the British Columbia foredeep preserves a 185 m thick record of OAE2. The organic carbon‐isotope and osmium‐isotope excursions can be correlated in detail with other Cenomanian–Turonian boundary sections around the world.

The Spatial and Temporal Evolution of Mixed Carbonate‐Clastic Mud‐Dominated Basin Fill Successions: The Middle to Late Devonian Shelf Margin, Western Canada

Basin Research, Volume 37, Issue 6, November/December 2025.
The spatial interplay between updip clastic and carbonate depositional systems and downdip detrital and biogenic mud dominated depositional systems are mapped temporally using the sequence stratigraphic method to predict the occurrence of aquifers, petroleum reservoirs and organic‐rich deposits. ABSTRACT Middle to Upper Devonian strata preserved in the

Determination of Trace Rhenium in Sandstone-type Uranium Deposits by Inductively Coupled Plasma-Mass Spectrometry with Magnesium Oxide Sintering

Yankuang ceshi, 2016
The average content of uranium in sandstone-type uranium deposits is 635 μg/g, whereas the content of rhenium is 0.3-1.9 μg/g. Because of low rhenium content, now precise determination of low Re in high U ores remains unresolved.
