Unraveling the Evolution of Silicic Volcanism in a Distributed Volcanic Field: Insights From Harrat Khaybar, Western Saudi Arabia

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Distributed basaltic volcanic fields commonly host minor but significant silicic magmas, the origin of which remains debated. At Harrat Khaybar (western Saudi Arabia; ca. 1.7 Ma to present), volcanic activity erupted compositions range from alkali olivine basalt to trachyte and comendite.

Air–Water Greenhouse Gases Exchange in Surface Waters of Deception Island (South Shetland Archipelago, Antarctica): Assessment of Drivers of Spatial Variability

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 10, October 2026.
Abstract Greenhouse gases (GHGs) such as Carbon Dioxide (CO2), Methane (CH4), and Nitrous Oxide (N2O) play critical roles in global climate change. CO2 dominates due to its high concentration and long atmospheric lifetime, while CH4 and N2O also exert strong heat‐trapping effects despite shorter residence times. Deception Island, in the Southern Ocean,

Hydraulic Barrier Optimization Using Random‐Walk Particle Tracking in Heterogeneous Media: Effects of Dispersion, Particle Discretization and Algorithmic Initialization

Water Resources Research, Volume 62, Issue 10, October 2026.
Abstract Hydraulic barriers (HBs) are commonly used for solute plume containment in polluted aquifers. Their long‐term sustainability depends on minimizing the cumulative pumping rate, Qtot ${Q}_{\text{tot}}$, required to ensure plume capture. Lagrangian random‐walk particle tracking (RWPT) is an effective approach for simulating advective‐dispersive ...

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 ...
