Impacts of Transient Critical Zone Evolution on Landslide Susceptibility and Hazard Across the Utuado Batholith, Puerto Rico

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 9, September 2026.
Abstract Landscapes in humid climates often experience rapid chemical and mechanical weathering that can change groundwater fluxes, drainage pathways, and frictional strength via alterations in subsurface mineral composition and matrix porosity. These changes to hillslope critical zone structure and strength should control landslide susceptibility ...

Dissolved Organic Matter Composition and Mineral Characteristics Jointly Control Adsorption Processes

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 9, September 2026.
Abstract Adsorption of dissolved organic matter (DOM) onto mineral surfaces plays a critical role in the global carbon cycle, influencing carbon stability and sequestration across terrestrial and aquatic ecosystems. Currently, it remains unclear if mineral properties or DOM composition are more relevant for predicting adsorption.

Block and Bomb Field of the 1888–1890 CE Eruption at La Fossa Cone (Vulcano, Aeolian Islands): Constraints on Conduit Stratigraphy and Eruptive Dynamics

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract Vulcanian eruptions are classically associated with the launch of ballistic ejecta and particularly with the production of breadcrust bombs. Morpho‐textural analysis of these ejecta provides critical insight into the poorly constrained processes controlling the complex dynamics of Vulcanian activity.

Petrogenesis and Tectonic Implication of the Newly Identified Rhyacian and Orosirian Orthogneisses in the Northwestern Part of the Gyeonggi Massif (Soyeonpyeongdo and Ganghwado Areas), South Korea: Constrained From Whole‐Rock Geochemistry and Zircon U‐Pb‐Hf Isotopic Compositions

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract The Gyeonggi Massif is one of the major Precambrian basements in the Korean Peninsula where Paleoproterozoic orthogneiss and paragneiss were widely exposed. In this study, newly identified Rhyacian to Orosirian meta‐igneous rocks from the northwestern Gyeonggi Massif (Soyeonpyeongdo and Ganghwado areas) were investigated to elucidate their ...

The Distinction Between Sn‐Mineralized and Sn‐Barren Granites in Sn Isotopes

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract Tin mineralization is commonly associated with highly evolved granites. However, not all highly evolved granitic rocks are mineralized with Sn. Comparative studies of Sn‐fertile and Sn‐barren granites can deepen our understanding of the key processes that lead to Sn enrichment in magmatic‐hydrothermal systems.

Contrasting Effects of Phosphate on Arsenic Mobility and Human Exposure in Agricultural Soils

GeoHealth, Volume 10, Issue 9, September 2026.
Abstract Arsenic in agricultural soils may pose human health risks due to elevated concentrations and increased soil ingestion associated with dust generation. However, the actual exposure depends on the fraction of As that becomes bioaccessible under gastrointestinal conditions. This study evaluates As mobility, bioaccessibility, and associated health
