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, EarlyView.
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.

Metallogenic Conditions and Prospecting Directions of Neogene Sandstone-type Uranium Deposits in Tarim Basin

Yuanzineng kexue jishu
The Tarim Basin is one of the main uranium-producing basins in northern China, but uranium deposits are primarily concentrated in the marginal areas of the basin.

Geological and geotechnical challenges on the Great Dyke of Zimbabwe and their impact on hardrock pillar design

Deep Underground Science and Engineering, EarlyView.
The Great Dyke of Zimbabwe is notable for its rich platinum group metal deposits but poses significant geological and geotechnical challenges due to its complex rock types and structural features. Traditional pillar design methods are insufficient for addressing these complexities; the study suggests incorporating advanced techniques such as machine ...

Petrography and geochemistry of sandstones from the middle Jurassic Zhiluo Formation in the northern margin, Ordos Basin: implications for provenance, tectonic setting, paleoweathering, paleoclimate, and sandstone-type uranium mineralization

Frontiers in Earth Science
This study aims to analyze the provenance of Middle Jurassic Zhiluo Formation sandstones exposed by drilling in the northern Ordos Basin (Bayingqinggeli area) and reconstruct the tectonic setting, paleoclimate, and paleoweathering conditions of their ...

A High-Resolution Atlas of Uranium-Neon in the H Band

, 2011
We present a high-resolution (R ~ 50 000) atlas of a uranium-neon (U/Ne) hollow-cathode spectrum in the H-band (1454 nm to 1638 nm) for the calibration of near-infrared spectrographs.

A rock brittleness index based on the postpeak energy release rate and damage surface characteristics for brittle hard rock

Deep Underground Science and Engineering, EarlyView.
This study examines energy evolution in rock rupture via triaxial direct shear tests, exploring the impact of confining pressure and temperature on fracture surface randomness. A novel energy‐based brittleness index is proposed, validated experimentally, and compared with existing methods for reliability and accuracy.

Validation of Bayesian modeling approach of uncertainty in organ doses using post-mortem measurements

Scientific Reports
The biokinetic and dosimetry models recommended by the International Commission on Radiological Protection do not incorporate dosimetric uncertainty. Recently, Bayesian approach—offering distribution of dose estimates rather than a single point value—has
