Classification of uranium deposits

Ore Geology Reviews, 1988
Abstract Genetic ore deposit classifications are more informative about mineralization processes than purely descriptive classifications and therefore are more useful. However, descriptive classifications are empirical whereas the former are speculative.

Diagenetic controls on porosity evolution and pore type organisation in microporous carbonate rocks: Evidence for mesogenetic porosity formation

Sedimentology, EarlyView.
ABSTRACT Microporous carbonate rocks typically record complex diagenetic histories driven by microbial activity and fluid interactions within multiple diagenetic environments. The relative roles of meteoric and burial diagenetic processes in pore evolution remain debated, particularly within Cretaceous carbonate systems of the Middle East, as does the ...

Geochronology and geochemistry of the Fogang granitic batholith and its implications for uranium mineralization

Frontiers in Earth Science
The E–W-striking Fogang granitic batholith represents the largest composite batholith in Guangdong Province. To date, the only known uranium deposit, the Pajiang deposit, has been identified in the southwestern portion of the Fogang granitic batholith ...

Outcrop and subsurface characterisation of a mixed tidal and wave‐influenced coastline (Triassic Red Beds, SE Spain)

Sedimentology, EarlyView.
ABSTRACT Paralic depositional systems are complex and heterogeneous sedimentary environments, presenting challenges for predicting reservoir architecture and connectivity. Their stratigraphic and facies variability arises from the dynamic interplay between fluvial, tidal and wave processes, and their sensitivity to sea‐level fluctuations, sediment ...

A Triassic chronostratigraphic and palaeogeographic framework for the Utsira High area, northern North Sea: Reconstructing a basin‐scale drainage divide

Sedimentology, EarlyView.
ABSTRACT The Triassic succession of the northern North Sea comprises a series of interbedded sandstones, mudstones and conglomerates deposited under a fluctuating arid to semi‐humid climate regime, which are often difficult to correlate regionally due to differing lithostratigraphic schemes and poor age control. Despite existing regional studies on the

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 ...

Vein uranium deposits

Ore Geology Reviews, 1993
Abstract Vein uranium deposits are epigenetic concentrations of uranium minerals, typically pitchblende and coffinite, in fractures, shear zones and stockworks. The uranium minerals are either the sole metallic constituents in the veins or, in polymetallic veins, they are accompanied by other metals, such as bismuth, cobalt, nickel, arsenic, silver ...

Uranium resource of Europe: Development status, metallogenic provinces and geodynamic setting

Energy Strategy Reviews
Since the 21st century, the closure of domestic uranium mines in Europe has made it one of the world's leading importers of uranium. In recent years, a series of policy adjustments have led to an improving situation for enriched uranium supply, yet the ...

Uranium-polymetallic mineralization relationship and comprehensive mineralization model in the Xiangshan ore field, South China: constraints from H-O-S-Pb-Sr multi-isotope data

Frontiers in Earth Science
The Xiangshan ore field, recognized as China’s premier volcanic-hosted uranium deposit cluster, has recently revealed significant exploration breakthroughs through the discovery of vertically zoned Pb-Zn-Ag-Cu polymetallic mineralization beneath shallow ...

Reconnaissance study of watershed and cave sediment sources discharging from a karst spring, Iowa

Agrosystems, Geosciences &Environment, Volume 9, Issue 3, September 2026.
Abstract Springs discharging from karst landscapes provide sustainable flows to natural ecosystems and support productive fish hatcheries but sediment discharging from springs threatens the long‐term sustainability of hatcheries. In this study, we conducted a reconnaissance study to evaluate watershed and cave sediment sources discharging to Siewers ...
