Ichnological insights into deoxygenation across the Cenomanian–Turonian Boundary Oceanic Anoxic Event 2 in the northern extent of Western Interior Seaway (west‐central Alberta)

Sedimentology, Volume 73, Issue 2, Page 355-390, February 2026.
ABSTRACT In‐depth ichnological and sedimentological analyses of the Cenomanian–Turonian boundary Oceanic Anoxic Event (OAE2) from the Western Interior Seaway of west‐central Alberta reveal a persistent physico‐chemically stressed setting. The interval is characterised by a dominantly diminutive and diminished ichnological assemblage, with familiar ...

Facies analysis provides new insights into event bed deposition in a hadal trench environment

Sedimentology, Volume 73, Issue 2, Page 441-477, February 2026.
ABSTRACT Hadal trenches preserve exceptional sedimentary archives of past geological events, yet their depositional processes remain poorly constrained. The Japan Trench captures complex earthquake‐triggered event beds that record repeated sediment‐gravity flows that deliver terrigenous and biogenic material into the trench, informing palaeoseismic ...

P‐T‐t‐d Evolution of Low‐Grade Metamorphic Xenotime, Eastern Alps (Austria)

Terra Nova, Volume 38, Issue 1, Page 65-76, February 2026.
ABSTRACT In situ LA‐ICP‐MS U‐Pb dating of xenotime was used to establish the age of low‐grade metamorphism in Permian metasediments of the Austroalpine Unit (Eastern Alps, Austria). Complexly zoned xenotime in chloritoid‐bearing metasedimentary samples possesses distinct MREE‐rich domains. In the eastern sample, this domain yielded a date of c. 135 Ma,

Satellite Data Trace Seasonal Freshwater Dispersion in Hudson and James Bays

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Freshwater dispersal controls stratification, circulation, and biogeochemical processes in Hudson and James Bay (HJB); however, limited field observations hinder understanding of how different freshwater types drive change. This study uses Aqua‐Moderate Resolution Imaging Spectroradiometer and Soil Moisture and Ocean Salinity‐Microwave Imaging

Mid‐Proterozoic Transient Oxygenation Events Linked to Enhanced Continental Chemical Weathering: Evidence From Carbonate Lithium Isotopes

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Potential drivers disrupting mid‐Proterozoic (∼1.8–0.8 Ga) environmental stasis remain poorly constrained. Here we examined carbonate Li isotopes from the ∼1.44 Ga Tieling Formation, North China, to evaluate the effects of continental chemical weathering on coeval oxygenation.

Isothermal Thermoluminescence Dating of Coral Reef Calcite: Implications for Sea‐Level Change

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Reconstructing past sea‐level changes is critical in Quaternary science. On remote oceanic reefs, aragonite‐to‐calcite alteration occurs during subaerial exposure, directly recording the timing of sea‐level fall. U–Th dating of coral calcite is challenging due to open‐system issues.
