1D Basin Modelling of Upper Jurassic to Upper Cretaceous Source Rocks in the Southern Pletmos Sub‐Basin, Outeniqua Basin, Offshore South Africa

Journal of Petroleum Geology, Volume 49, Issue 4, Page 1382-1411, October 2026.
ABSTRACT The Pletmos sub‐basin in the Outeniqua Basin, offshore South Africa, is divided by the Superior, Pletmos and Plettenberg faults into northern and southern depocentres. In this study, geological and organic geochemical data together with 1D basin modelling were used to investigate the burial, thermal and maturation histories, and the timing of ...

De‐Coupled Water and Nitrogen Translocation From Subsoil to Canopy of Temperate Forest Trees

Plant, Cell &Environment, Volume 49, Issue 10, Page 7676-7691, October 2026.
ABSTRACT Water and nitrogen (N) transport from soil to canopy play a central role in tree functioning, yet direct evidence for their timing and coupling in mature forests remains scarce. We report results from a paired dual‐isotope (2H, 15N) tracer experiment in a temperate forest, comparing water and nitrate uptake patterns across tree species ...

Reconfiguration of Mercury's Exosphere During Strong Space Weather Events

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Mercury is exposed to various space weathering processes, which alter the surface and cause emission of atoms and molecules into the exosphere. The exosphere thus allows remote insights into the surface composition and erosion processes, with the emission of refractory elements such as Ca and Mg typically being dominated by micrometeoroid ...

Diagenetic evolution and geochemical controls on carbonate platform development in the Middle Eocene Jahrum Formation, Zagros Basin

The Depositional Record, Volume 12, Issue 4, September 2026.
Integrated petrographic, mineralogical and geochemical workflow for reconstructing the diagenetic evolution of the Middle Eocene Jahrum Formation in the Zagros Basin. The diagram illustrates the methodological framework combining field observations, laboratory analyses (XRD, SEM‐EDS, stable isotopes, cathodoluminescence), pyrite framboid geochemistry ...

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 ...

Riverine nitrate and nitrification cannot be the only sources for nitrate assimilation in the Amazon River Plume margins

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract The Northern Amazon River Plume plays a crucial role in carbon sequestration and nitrogen cycling. This study quantified NO3− budgets along the plume during a period of high discharge, revealing NO3− uptake rates in excess of inputs from riverine sources and nitrification beyond 5°N.

Embodied, Enacted, and Multimodal: Exploring Science Teachers’ Metaphors in Authentic Classroom Contexts

Science Education, Volume 110, Issue 5, Page 1469-1496, September 2026.
ABSTRACT Over the past decades, science education research has extensively examined the role of metaphors in teaching and learning science. However, much of the existing research has focused on verbal manifestations of metaphors, thereby overlooking aspects of metaphors that may occur in non‐verbal form. This study reconceptualises metaphors as dynamic
