Rethinking Collinearity in Self‐Organizing Maps: Evidence From Geophysical Data Classification

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 2, April 2026.
Abstract This study examines the impact of collinearity on unsupervised machine learning algorithms (UMLAs), specifically Self‐Organizing Maps (SOMs), for detecting lithological boundaries in geophysical data. Using a multi‐scale experimental framework that includes bivariate isotropic clusters, geologically complex Noddy simulations, and real‐world ...

Transformation of Fe-bearing minerals from Dongsheng sandstone-type uranium deposit, Ordos Basin, north-central China: Implications for ore genesis

American Mineralogist, 2022
Abstract Iron-bearing mineral assemblages and their distribution patterns directly reflect the redox environment in sediments, which plays a decisive role in the migration and precipitation of U. The Dongsheng sandstone-type U deposit hosted in fluvial and/or deltaic sandstones of the lower member of the Middle Jurassic Zhiluo Formation ...

Integrating Deep Learning and Distance‐Based Clustering to Optimize the Field Scale In Situ Uranium Leaching System in Heterogeneous Reservoirs

Water Resources Research, Volume 62, Issue 3, March 2026.
Abstract Utilization of the integrated simulation‐optimization models for supporting decisions of the in situ leaching (ISL) design of uranium (U) mining is often hampered by the physicochemical heterogeneity within the sandstone reservoirs. Nevertheless, the conventional way suffers from a high conceptual uncertainty due to almost ubiquitous ...

The Neoproterozoic Throssell Range Group, Western Australia: A Peri‐Marginal Continental Basin in Rodinia and Its Implications for the Centralian Superbasin

Basin Research, Volume 38, Issue 1, January–February 2026.
This study of recent exploration drillcore reveals two sequences separated by a disconformity. Basal alluvial fan to shallow marine lithofacies suggest reactivation of basement faults, and a distinct upwelling signature points to a flooded margin, controlled by differential subsidence of diverse Proterozoic lithosphere.

Explainable Quantitative Analysis of Uranium Spectral Gamma‐Ray Logging With Fuzzy Multitarget Regression Model

Applied Computational Intelligence and Soft Computing, Volume 2026, Issue 1, 2026.
Current machine learning algorithms have achieved remarkable success in quantitatively interpreting spectral gamma‐ray logging for uranium exploration. However, several challenges remain: (1) Existing models typically neglect intervariable dependencies among multiple output variables and (2) they generally lack interpretability. To address these issues,

Digital Mapping of Soil Vanadium Across Australia

European Journal of Soil Science, Volume 76, Issue 6, November–December 2025.
ABSTRACT Vanadium (V) is increasingly recognised as a critical mineral due to its potential for decarbonisation technologies. Australia holds an estimated quarter of global V resources, yet there is limited knowledge of how these resources are distributed across the country.

Joint Inversion of Electromagnetic and Direct Current Resistivity Data Using Trust Regions. Application to Uranium Exploration in the Athabasca Basin

Geophysical Prospecting, Volume 73, Issue 8, October 2025.
ABSTRACT The Athabasca Basin (Saskatchewan, Canada) is a world‐class uranium mining province hosting high‐grade high‐tonnage deposits. Electromagnetic data and direct current resistivity data are essential tools to detect deep geoelectric structures associated with mineralization.

Geomechanics of Flooding‐Induced Microseismicity—Implications for Post‐Mining Environments

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 9, September 2025.
Abstract Seismicity related to mining has gained considerable public attention in the last decades and is one of the reasons for mine closures in Germany. The seismicity in the Ruhr coal mining district of Germany has been monitored by different regional and (temporal) local networks and is classified as purely mining‐induced without evidence for ...

Mineralization at Different Structural Levels in the Crust

Acta Geologica Sinica - English Edition, Volume 99, Issue 4, Page 1042-1058, August 2025.
Abstract Metallogenic research on structural levels can reveal vertical patterns of mineralization and facilitate the deep exploration of economic minerals. However, research focusing on the correlation between structural levels and mineralization remains limited.
