Radiolysis and Fe‐Biotite Alteration: Questioning the Origin of H2‐Bearing Fluid Inclusions in the Yorke Peninsula Granites, South Australia

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Multiple drillings in the Yorke Peninsula, South Australia, recently confirmed the presence of natural hydrogen (H2) in shallow sedimentary units. While radiolysis and Fe‐oxidation in the basement are potential generation mechanisms, their respective contributions remain unconstrained.

Seismic attribute and well-log analysis for channel characterization in the upper San Andres and Grayburg formations of the Midland Basin, Texas

Energy Geoscience
The Permian Basin is one of the most prolific, and currently one of the most active, oil and gas basins in the USA. The Lower Permian strata in the Permian Basin have produced more than 14 billion barrels of oil (BBO), making it the largest volume of ...

Ediacara Obscura: Unveiling Hidden Magnetisations in the Fen Complex, Southern Norway

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.
Abstract Paleomagnetic directions found in Ediacaran (635–539 Ma) rocks are widely dispersed, which has led to conflicting hypotheses about tectonic regimes and geomagnetic field behavior during this period, and raised doubts about the fidelity of the paleomagnetic record.

Ostracods from freshwater and brackish environments of the Carboniferous of the Midland Valley of Scotland : the early colonization of terrestrial water bodies [PDF]

, 2012
The Mississippian Strathclyde Group of the Midland Valley of Scotland yields some of the earliest non-marine ostracods. The succession records shallow marine, deltaic, estuarine, lagoonal, lacustrine, fluvial and swamp environments representing a series ...

Post‐Eocene 90° CCW Rotation of Sardinia‐South Corsica: Paleomagnetic Evidence From Permian‐Cretaceous Sediments of Nurra (NW Sardinia)

Tectonics, Volume 45, Issue 5, May 2026.
Abstract The paleomagnetism of Miocene calc‐alkaline volcanics and sediments from Sardinia has firmly showed that the Corsica‐Sardinia microplate rotated 50°–60° counterclockwise (CCW) with respect to Europe between 21 and 15 Ma, during its drift from the Provencal margin. However, Permian to Eocene rocks from central‐south Sardinia revealed higher (up

Shifting the Paradigm: Redefining the Chronostratigraphy of the Triassic Rewan Group, Bowen Basin, Australia

Basin Research, Volume 38, Issue 3, May–June 2026.
New U–Pb zircon dating shows the Rewan Group was deposited between ~250 and 233 million years ago and that sedimentation shifted across the basin through time, with earlier deposition in the foredeep and later deposition in the back bulge. Testing multiple dating approaches and grain‐selection strategies improves confidence in these age estimates and ...

REVISIÓN DE ASTEROTHECA GOLONDRINENSIS HERBST, HELECHO PÉRMICO DE PATAGONIA, ARGENTINA

Publicación Electrónica de la Asociación Paleontológica Argentina, 2010
New specimens of Asterotheca golondrinensis Herbst found in the type area (Bajo de La Leona, Santa Cruz province) and in the Tepuel-Genoa Basin (Chubut province), allow a new definition of pinnular characters (margins are shown to be toothed).
