Sandstone-type uranium mineralization coupled with extensional tectonics

Nuclear Engineering and Technology
While compressional tectonics has long been recognized as a significant factor in uranium mineralization, the role of extensional tectonics remains comparatively understudied. This investigation analyzes representative sandstone-hosted uranium provinces,

Relationship between sandstone-type uranium deposits and hydrocarbon in the northern ordos basin

IOP Conference Series: Earth and Environmental Science, 2017
The Ordos Basin is one of the largest proliferous basins and also one of the most important uranium-bearing basins in China. It is characterized by the coexistence of petroleum and uranium in the northern part of the basin. To understand the coexistence mechanism, more studies are called for on the genesis of sandstone-type uranium deposits in the ...

A Middle and Late Devensian sequence from the northern part of Kents Cavern (Devon, UK)

Journal of Quaternary Science, Volume 40, Issue 6, Page 925-943, August 2025.
Abstract 1920s/30s excavation of a Middle Devensian sequence in the northern part of Kents Cavern recovered important Late Middle and Early Upper Palaeolithic archaeological material, including Britain's oldest known Homo sapiens remains. Questions remain about this material, including how it came to be in the cave.

Experimental study of the influence of borehole parameters on prompt fission neutron uranium logging and its corrections

Nuclear Engineering and Technology
In prompt fission neutron uranium logging, borehole environmental parameters affect the measured results and must be corrected. In order to explore the influence of borehole parameters on the interpretation of logging results, this paper builds a ...

Pore characteristics and seepage simulation of sandstone-type uranium ore in the 512 deposit, Xinjiang

地质科技通报
Objective In situ leaching is a uranium extraction process in which a solution reacts with uranium-bearing minerals in a saturated aquifer and then uranium in the flowing solution is extracted through exchange.

Hydrocarbons as ore fluids [PDF]

, 2017
Conventional wisdom holds that aqueous solutions are the only non-magmatic fluids capable of concentrating metals in the Earth’s crust. The role of hydrocarbons in metal concentration is relegated to providing geochemical barriers at which the metals ...
