Revealing Transport, Dissolution, and Precipitation Behaviors in Electrokinetic‐Geochemical Reaction System at Pore‐to‐Core Scales

Water Resources Research, Volume 61, Issue 7, July 2025.
Abstract Net‐zero carbon targets drive the development of new underground activities such as hydrogen storage and in situ critical mineral recovery, all of which involve geochemical reactions between minerals and fluid/ion transport. Understanding these processes is key to optimizing efficiency and minimizing environmental impacts.

Ground zero soil sampling: Trinity, 1945

Geology Today, Volume 41, Issue 4, Page 137-146, July/August 2025.
At Trinity—the world's first nuclear weapons testing site—large quantities of soil were drawn into the fireball to redeposit either downwind as radioactive fallout or in the near‐field as a unique, anthropogenic silicate glass trinitite. Manhattan Project physicists and chemists came to see soils at the Trinity site as a useful medium to assess the ...

Geochemical and Documentary Topography of a Medieval Silver Valley: Detection of Workshops and Identification of Their Function

Archaeological Prospection, Volume 32, Issue 2, Page 345-374, April/June 2025.
ABSTRACT This paper presents the interdisciplinary investigation (archaeology, geochemistry, history) of a medieval silver and lead production site located in southern France, in the Minier valley (Occitanie, Aveyron, Le‐Viala‐du‐Tarn). In order to identify the production sites, in situ geochemical surveys were carried out using a portable X‐ray ...

Leaf Accumulation Capacity of Herbaceous Plants Growing on Fields Contaminated With Anthropogenically Induced Potentially Toxic Elements Under Natural Soil Conditions

Land Degradation &Development, Volume 36, Issue 2, Page 630-642, 30 January 2025.
ABSTRACT Estimation and knowledge of potentially toxic elements (PTEs) in soils and herbaceous plants are vital for ecotoxicological reasons. This study explored PTE accumulation in the aerial organ (leaf) of herbaceous plants in PTE‐contaminated soils in a linear transect of three localities close to the Litavka River in Pribram, Czech Republic.
