Flexural bulges and foredeep basins: Dynamic tectonic control on shifting depocentres and condensed facies, Upper Cretaceous (Santonian), Western Canada Foreland Basin

The Depositional Record, Volume 12, Issue 4, September 2026.
Allostratigraphically defined mudstone packages show marked along‐strike thickness variation, interpreted to be related to shifting thrust activity in the orogen; loading cycles lasted about 750 kyr. Close to the orogen, the forebulge is mantled by shelly sandstone whereas far from the orogen, the forebulge is typified by organic‐rich mudstone ...

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 ...

Iron‐Based Catalysts on Tailored Alumina Supports for COx‐Free Methane Decomposition to H2 and Carbon

ChemistryOpen, Volume 15, Issue 9, September 2026.
Fe‐10ZrAl catalyst enables catalytic methane decomposition into COx‐free H2 and solid carbon. ZrO2‐modified alumina improves Fe particle stabilization, reducibility, and carbon growth behavior, giving the best performance among the tested catalysts with 76.5% CH4 conversion and 74.1% H2 yield at 800 °C.

Geophysical Investigation of a Thermal Field in Abu Dhabi, United Arab Emirates

Earth and Space Science, Volume 13, Issue 9, September 2026.
Abstract In the Abu Dhabi Emirate, near Madinat Zayed and Liwa, studies have identified high geothermal gradients and high‐heat‐flow areas. Assessing the geothermal potential in this region requires a detailed mapping of subsurface geological formations and their thermal properties.

Re‐Evaluating the Thermogenic Decarbonation During Large Igneous Provinces Emplacement Using Temperature‐Dependent Thermal Properties

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract Large Igneous Provinces emplacement drives mass extinctions through rapid carbon release, but the relative contributions of magmatic degassing versus thermogenic decarbonation remain debated. Here, we incorporate temperature‐dependent thermal parameters into models of contact metamorphism around intruding sills.

Depositional History of the Namibian Mud Belt Reveals Late Holocene Weakening of the Benguela Coastal Current

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 9, September 2026.
Abstract We investigate late Holocene changes in the northern Benguela Upwelling System using a multi‐proxy approach on shallow shelf deposits from the Namibian mud belt. Three sediment cores characterized by organic carbon‐rich, anoxic, and partly gas‐bearing sediments were retrieved along a sampling transect at 23°S in August 2019.

Persistent‐Homology‐Based Descriptors of Pore Heterogeneity for Generalized Permeability Prediction

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Characterizing pore‐structure heterogeneity is essential for understanding and predicting fluid transport processes in geological formations. However, it remains challenging because conventional descriptors capture only partial structural information, making it difficult to consistently distinguish complex pore structures across lithologies ...

Provenance Constraints on Early India–Asia Collision: Evidence From the Late Cretaceous–Early Cenozoic Sulaiman–Katawaz Basin Fill

Basin Research, Volume 38, Issue 5, September‐October 2026.
Integrated detrital zircon U–Pb, Nd–Sr isotopes and thermochronology record western Indian‐margin provenance reorganisation. Late Cretaceous–Palaeocene sediment supply was Indian‐affinity; Asian‐affinity input appeared across the Palaeocene–Eocene transition (~56.5–54.7 Ma), suggesting India–Asia collision was underway, while mixed provenance persisted

Thallium Isotopes Across the Smithian‐Spathian Boundary: Evidence for Anoxia Throughout Most of the Early Triassic

Geobiology, Volume 24, Issue 5, September/October 2026.
ABSTRACT Following the largest known Phanerozoic extinction, the end‐Permian mass extinction, the Early Triassic is often considered an interval of slow biotic recovery. During this time, the minor Smithian‐Spathian extinction occurred, further delaying the biotic recovery of this epoch.
