Kasimovian (late Pennsylvanian) cornute rugose corals from Egypt: taxonomy, facies and palaeogeography of a cool-water fauna from northern Gondwana

Swiss Journal of Palaeontology, 2023
A strongly endemic Upper Pennsylvanian (Kasimovian) rugose coral association consisting of small, mostly non-dissepimented, simple structured and poorly diversified species is studied from the lower member of the Aheimer Formation (Western side of the ...

Late Carboniferous Paleomagnetism From North Qiangtang Block Reveals a Multibranched Paleo‐Tethys Ocean

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The North Qiangtang Block occupies a pivotal position within the eastern Tethyan realm, and its paleogeographic reconstruction is critical for constraining Tethyan geometry and evolution. However, its Late Paleozoic paleogeography and Paleo‐Tethyan Ocean–continent configuration remain controversial due to limited reliable age‐constrained ...

Examining Local Climate Variability in the Late Pennsylvanian Through Paleosols: An Example from the Lower Conemaugh Group of Southeastern Ohio, USA

Geosciences, 2012
Three temporally close stratigraphic sections were excavated in Glenshaw Formation of Athens County, Ohio. The described units are Upper Pennsylvanian (Gzhelian, 305–302 Ma) and located in the distal portion of the Appalachian foreland basin.

Records of organic carbon isotopic composition (δ13Corg) and volcanism linked to changes in atmospheric pCO2 and climate during the Late Paleozoic Icehouse [PDF]

, 2021
The Late Paleozoic Icehouse (LPI) provides a deep-time perspective for climate-glaciation-environment coevolution and offers potential insights into future climatic and environmental predictions.

Distal Marine Mercury Signals in Peak Late Paleozoic Ice Age: Implications for Aeolian Versus Volcanic Inputs

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract An investigation of the relationships among large igneous province (LIP), carbon cycling, and climate change is central to understanding Earth system. During Glacial III, the most intense phase of Late Paleozoic Ice Age, the influence of coeval LIP on the carbon cycle and climate remains debated.

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

New Zealand Geological Timescale 2025

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
New Zealand Geological Timescale 2025 (NZGT 2025) is the first comprehensive update and revision of the New Zealand Geological Timescale in a decade. The criteria used to establish age ranges of New Zealand Stages within the NZGT have been reviewed, calibrated, and revised where required against the 2023/04 International Chronostratigraphic Chart and ...

Choice of conodont Idiognathodus simulator (sensu stricto) as the event marker for the base of the global Gzhelian stage (Upper Pennsylvanian series, Carboniferous system)

, 2008
cc-by-ncWe propose that the level at which the conodont species Idiognathodus simulator (Ellison 1941) (sensu stricto) first appears be selected to mark the base of the Gzhelian Stage, because we believe that this is the optimal level by which this ...

Rupture and Relamination of Continental Lithosphere in a Subduction System (Variscan Orogeny, SW Iberia)

Tectonics, Volume 44, Issue 7, July 2025.
Abstract Relamination is closely connected to subduction zones. Despite the numerous high‐P metamorphic belts recognized on Earth, relamination remains a poorly documented process. We present a continental subduction zone where the exhuming high‐P rocks became a relaminant under the upper plate.

The Uplift of Armorica and the Bretonian Movements of the Variscan Orogeny‐New Insights From Detrital Zircons in the Early Carboniferous Terrigenous Rocks of the Laval Basin (Armorican Massif, France)

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 6, June 2025.
Abstract In the French Armorican Massif, the Bretonian phase of the Variscan orogeny has been defined by the Late Devonian (Famennian‐Frasnian) erosion gap, and the Early Carboniferous (Tournaisian) syntectonic terrigenous deposits of the l’Huisserie formation in the Laval basin in the Central‐North Armorican Domain, ascribed to the Armorica ...
