Sedimentary facies and stacking patterns of fluvio‐deltaic and ‐estuarine deposits from the Palaeoarchean Moodies Group in the Stolzburg Syncline (Barberton Greenstone Belt, South Africa)

The Depositional Record, Volume 12, Issue 4, September 2026.
Drillcore BASE‐5B from the Stolzburg Syncline, Barberton Greenstone Belt, reveals a coarsening‐upward, river‐dominated fluvio‐deltaic succession transitioning upward to a fining‐upward, tide‐dominated‐estuarine succession. Abstract Investigating fluvio‐marine depositional environments from early geological times is of great importance, as they provide ...

Sedimentology and geochemistry of the recent sediments of the river system on Hurd Peninsula, Livingston Island, Antarctica

The Depositional Record, Volume 12, Issue 4, September 2026.
This study investigates the sedimentology and geochemistry of recent sediments from ephemeral river systems on Hurd Peninsula, Livingston Island, Antarctica. These systems are important for understanding sedimentary and geochemical processes in unique polar environments.

Morphological Changes and Alterations in Erosion–Accretion Patterns in a Semiarid Brazilian River

Earth Surface Processes and Landforms, Volume 51, Issue 9, September 2026.
Flow regulation by the Castanhão Dam significantly altered discharge dynamics and reduced sediment transport in the Jaguaribe River. Long‐term analysis (1958–2025) reveals attenuated flood peaks, decreased channel migration and progressive downstream stabilisation, highlighting persistent geomorphic adjustments in a regulated semiarid fluvial system ...

Numerical Modelling of Late Pleistocene to Holocene Earthquake‐Induced Progressive Rock Slope Damage in the Paraglacial Serpentine Valley, Prince William Sound, Alaska

Earth Surface Processes and Landforms, Volume 51, Issue 9, September 2026.
Numerical modelling of earthquake‐induced progressive rock slope damage in the paraglacial Serpentine valley, Prince William Sound, Alaska. Repeated seismicity generates rock mass damage that may have conditioned areas of the slope for failure during present‐day ice retreat.

Long‐Term Population Declines of Habitat‐Shifting Species in the City: A Living Planet Index Approach for Berlin, Germany

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
We applied two global biodiversity indices at a city scale and revealed significant declines in odonate and amphibian populations in freshwater systems over several decades. Our study demonstrates the effectiveness of both indices as a baseline for fulfil urban‐related biodiversity framework targets if suitable biodiversity time series are available ...

Geochemical and Geological Investigation of Skarn‐Type Pb–Zn Mineralization in Hastanetepe (Balya‐Balıkesir, Türkiye): An Approach Based on Fluid Inclusions, Sulphur Isotopes and Geochemical Data

Geological Journal, Volume 61, Issue 9, Page 2940-2957, September 2026.
Integrated petrographic, mineralogical and geochemical data from the Hastanetepe Pb–Zn deposit (Balya, Türkiye) reveal multi‐stage hydrothermal alteration and a magmatic sulphur source. Fluid inclusion and sulphur isotope results indicate a complex fluid evolution responsible for skarn‐type Pb–Zn mineralization along limestone–dacite contacts ...
