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.

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 ...

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 ...

Late Visean to Gzhelian foraminiferal assemblages from the Paleo-Tethyan seamount-type carbonates in the Changning-Menglian Belt, westYunnan, southwest China

, 2012
The Changning-Menglian Belt of West Yunnan, Southwest China is known as a closed remnant of the Paleo-Tethys. Carboniferous to Permian carbonates of mid-oceanic seamount origin from the central part of this belt is studied at the Yutangzhai Section for

The neodiapsid Thadeosaurus colcanapi from the upper Permian of Madagascar

Papers in Palaeontology, Volume 11, Issue 2, March/April 2025.
Abstract The enigmatic neodiapsid Thadeosaurus colcanapi (Lower Sakamena Formation, southwestern Madagascar), sole species of the genus Thadeosaurus, is revised here. The attribution of 12 of the 21 referred specimens is confirmed, spanning all ontogenetic stages, and the anatomy of Thadeosaurus is redescribed in detail with comments on ontogenetical ...

Late syn‐rift to early post‐rift basin fill dynamics of a mixed siliciclastic‐carbonate succession banked to a basement high, Hornsund, southwestern Spitsbergen, Arctic Norway

Basin Research, Volume 36, Issue 4, July–August 2024.
The depositional evolution of the ?Pennsylvanian – ?lower Permian Treskelodden Formation (Spitsbergen) is illustrated in the four conceptual block diagrams representing evolution from an alluvial/fluvial dominated environment in phase 1a and 1b (A, B), through a nearshore storm/tide dominated depositional environment in phase 2a + 2b (C), to a marine ...
