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.

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 ...

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.

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 ...

Tectonics, Volume 45, Issue 4, April 2026.Abstract Our understanding of subduction initiation remains limited by the difficulty of making direct observations of geologically recent examples. In the geologic record, supra‐subduction zone ophiolites are often interpreted to record syn‐initiation slab rollback and upper plate extension. Unfortunately, many ophiolites are decoupled from records of
