Genetic Mechanism of Tabular-Shaped Orebody of the Hailijin Sandstone-Type Uranium Deposit in the Songliao Basin: Constraints on the Clay Mineralogy of Ore-Bearing Sandstone

open access: yes, 2023
The Hailijin (HLJ) sandstone-type uranium deposit was newly discovered in the southwestern Songliao Basin in recent years. Different from the roll-front orebody of the sandstone-type uranium deposits with (phreatic oxidation) interlayer redox origin (or ...

Multifractal Characteristics of Uranium Grade Distribution and Spatial Regularities in a Sandstone Type Uranium Deposit in Xinjiang, China

open access: yesFractal and Fractional, 2023
Based on the analysis of the spatial distribution of uranium grade in 348 boreholes of a uranium deposit in Xinjiang, the enrichment and spatial variation of uranium ore in two stopes of the deposit are discussed by using multifractal theory. The distribution characteristics of uranium ore of the two stopes are studied by multifractal parameters: the ...

Uranium Deposits of Erlian Basin (China): Role of Carbonaceous Debris Organic Matter and Hydrocarbon Fluids on Uranium Mineralization

open access: yes, 2021
The relationship of sedimentary organic matter, oil-gas and sandstone-type uranium (U) deposits is the key problem of U-mineralization. Whether migrate hydrocarbons participate in U-mineralization is still a controversy.

Full-scale pore size distribution features of uranium-bearing sandstone in the northwest of Xinjiang, China

open access: yesRoyal Society Open Science, 2021
As an important nuclear fuel, uranium in sandstone uranium deposits is mainly extracted by in situ leaching. The porosity of sandstone is one of the important indexes determining in situ leaching efficiency.

Control of tectonic uplift and denudation on uranium mineralization in the eastern Junggar Basin

open access: yesMeitan xuebao, 2023
There is a close dynamic coupling relationship between tectonic and mineralization. Long-term research and observation have found that the formation and location of sandstone-type uranium deposits are obviously controlled by the formation of target layer

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

open access: yesYankuang 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.

Prediction of channel sandbody distribution in the lower section of Sifangtai Formation at the southern end of Chang Placanticline in Songliao Basin [PDF]

open access: yesE3S Web of Conferences, 2021
The channel sand bodies in the lower section of the Sifangtai Formation in the Songliao Basin are rich in uranium resources. The development of channel sand body distribution prediction is of great significance for guiding the exploration of sandstone ...
