The Depositional Record, Volume 12, Issue 2, April 2026.During the Late Permian, the rise of the Gondwanides Belt trapped marine waters, giving birth to a vast megalake. This lake shifted between overfilled, balanced‐fill and underfilled stages that are recorded by high‐frequency accommodation changes, while meteorological seiches shaped the sedimentary dynamic and produced heterolithic beds.

U‒Pb ages and Hf isotopic composition of zircons in Austrian last glacial loess: constraints on heavy mineral sources and sediment transport pathways [PDF]
, 2015 Loess sediments in Austria deposited ca. 30‒20 ka ago yield different zircon age signatures for samples collected around Krems (SE Bohemian Massif; samples K23 and S1) and Wels (half-way between the Bohemian Massif and the Eastern Alps; sample A16 ...

Geochemical Disequilibrium at the Brittle‐Ductile Transition
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 4, April 2026.Abstract We investigate the microtextural, microchemical, and isotopic effects of late‐stage ductile deformation in quartzite mylonites and kyanite–muscovite–quartz veins from the Raft River shear zone (Utah). Quartz microstructures record pervasive disequilibrium, expressed by unannealed features including undulatory extinction, deformation lamellae ...

The making of pure quartzose sand in continental interiors: Paraná River (Brazil and Argentina)
Sedimentology, Volume 73, Issue 3, Page 802-837, April 2026.ABSTRACT As part of a comprehensive project on sedimentary processes in South America, this study focuses on sediment generation in the intracratonic Paraná Basin and monitors the evolution of sand composition along the Paraná River from central Brazil to the Río de la Plata estuary in Argentina.

Laser ablation U/Pb age patterns of detrital zircons in the Schlieren Flysch (Central Switzerland): new evidence on the detrital sources [PDF]
, 2018 The palaeogeographic attribution of the Schlieren Flysch and its counterparts in the Gurnigel Nappe is still a matter of debate. These Late Alpine deep-sea trench deposits show a variable tectonic thrust relationship with other nappes inferring either an

L'unité de la Boghen (Nouvelle-Calédonie, Pacifique SW): un complexe d'accrétion jurassique. Données radiochronologiques préliminaires U-Pb sur les zircons détritiques. [PDF]
, 2002 La datation des zircons détritiques de l'unité de la Boghen permet d'attribuer un âge post-liasique à cet ensemble, autrefois considéré comme le " socle anté-permien " de la Nouvelle-Calédonie.
