Minimal Perturbation of the Global Mercury Cycle by the Paraná–Etendeka Large Igneous Province (PE–LIP) During the Onset of the Valanginian Weissert Event

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 7, July 2026.
Abstract The Valanginian positive carbon isotope excursion (Weissert Event, ca. 135 million years ago) documents a major global carbon cycle and climate perturbation. Radioisotopic dating suggests that this event was broadly contemporaneous with an interval of profoundly enhanced volcanic activity during the emplacement of the Paraná–Etendeka Large ...

Impact of Fluid Flow on Bacterial Carbon and Sulfur Cycling, Mineral Precipitation, and Transformation in Hydrothermal Sediments off the Coast of Milos

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.
Abstract Hydrothermal fluid flow not only shapes mineral deposition on the ocean floor but also creates ecological niches by altering temperature and energy availability. In these niches, microbial life thrives and has an additional, often unrecognized impact on mineral formation. In a newly discovered vent field at water depths of 100–200 m off Milos,

Redox‐Induced Transformations of Iron Oxides Enhance Soil Organic Carbon Stabilization in an Estuarine Soil

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.
Abstract We investigated temporal changes in operational Fe pools and their association with soil organic carbon (SOC) fractions in an estuarine soil affected by the deposition of iron‐rich mine tailings over 6 years in Southeast Brazil. Sequential Fe extractions revealed a 56% decrease in Fe extracted with citrate–bicarbonate–dithionite alongside a 50%

Low Chemical Weathering Intensity, Enhanced Erosion, and Euxinic Conditions Along the Norwegian Margin During the Paleocene‐Eocene Thermal Maximum

Paleoceanography and Paleoclimatology, Volume 41, Issue 7, July 2026.
Abstract The Paleocene–Eocene Thermal Maximum (PETM; ∼55.9 Ma) was a rapid global warming event marked by intensified hydrological cycling, enhanced continental weathering, and widespread ocean deoxygenation. Although the extent of anoxic basins during the PETM is relatively well documented, the contribution of high‐latitude continental weathering to ...

Drilling the Marathousa palaeo‐lake in Greece (Peloponnese): inferring the environmental context of a Middle Pleistocene archaeological site

Boreas, Volume 55, Issue 3, Page 866-884, July 2026.
The Megalopolis Basin is located in the central Peloponnese (Greece), a region that is situated along one of the primary Pleistocene biogeographical corridors for intracontinental hominin migration. The basin comprises several hundred metres of Plio‐Pleistocene sediments alternating between clastics and lignites.
