In-situ Micro-scale Pb Isotope Identification Characteristics of Metallogenic and Non-metallogenic Pyrites in Sandstone-type Uranium Deposits

Yankuang ceshi, 2022
BACKGROUND Sandstone-type uranium deposits contain a large number of pyrites of different shapes and stages. It is difficult to accurately discriminate the pyrite formed before, during or after the metallogenic period solely by observation of pyrite ...

Marine Isotope Stage 4 glaciation in northern England, UK: Evidence from Victoria Cave, North Yorkshire

Journal of Quaternary Science, EarlyView.
ABSTRACT Victoria Cave, north Yorkshire, England, contains a long sequence of Pleistocene clastic sediments and calcite flowstones. Earlier work, using U–Th dating, established that the flowstone units formed in interglacial stages corresponding to Marine Isotope Stages (MIS) 13, 11, 9, 7 and 5.

Constraints of the sequence stratigraphic structure of uranium-bearing series on mineralization in Qianjiadian uranium deposit, Songliao Basin

地质科技通报, 2021
Understanding the stratigraphic structure of uranium-bearing rock series in sandstone-type uranium deposits and its constraints on uranium mineralization is the basis of understanding the uranium metallogenic regularity and mineralization. In this paper,

Alternative approaches to dryland reclamation enhance vegetation cover and soil stability at a former uranium mine

Restoration Ecology, EarlyView.
Abstract Introduction Conventional reclamation methods to recover dryland ecosystems after mineral extraction often have low success. Alternative reclamation techniques may help overcome the many challenges to establishing persistent native vegetation and stable soils.

Selenium in some oxidized sandstone-type uranium deposits [PDF]

, 1963
A report about selenium and other trace metals in samples from some oxidized sandstone-type uranium deposits that demonstrate that concentrations of as much as 0.1 percent selenium are not uncommon in the immediate vicinity of uranium concentrations.

Iowa Population Exposures to Metals and Metalloids in Well Water

Environmental Toxicology, Volume 41, Issue 7, Page 459-469, July 2026.
ABSTRACT Previous Iowa studies suggest low levels and chronic arsenic exposures are associated with prostate cancer. The rural Iowa population heavily relies on private wells for drinking water resources and thus is vulnerable to contaminants such as heavy metals found in well water.

Estimation of Filtration Properties of Host Rocks in Sandstone-Type Uranium Deposits Using Machine Learning Methods

IEEE Access, 2022
The nuclear decay of uranium is one of the cleanest ways to meet the growing energy demand. The uranium needed for power plants is mainly extracted by two methods in roughly equal amounts: quarries (underground and open pit) and in-situ leaching (ISL ...

Bayesian Inversion of Electrical Resistivity Tomography Data for Uranium Exploration Through a Localized Ensemble‐Based Approach

Geophysical Prospecting, Volume 74, Issue 4, May 2026.
ABSTRACT The electrical resistivity tomography (ERT) is a geophysical method commonly used in mining exploration to reconstruct the subsurface resistivity. The associated inverse problem is typically addressed using deterministic approaches that minimize an objective function and guarantee fast convergence.

Shear-Hosted Uranium Deposits: A Review

, 2020
A group of uranium deposits is described that is hosted within polyphase shear zones. The group is economically significant, collectively containing over 500,000 tonnes of uranium and several examples have been or are being mined.
