Linking palaeo‐wildfire to depositional environmental and ecological dynamics of an Early–Middle Pennsylvanian fluvial‐tidal transition zone—Palynology and pyrolysis evidence

The Depositional Record, Volume 12, Issue 1, February 2026.
The Pennsylvanian landscape in the Forest City basin was characterised by low‐lying lycopod tree and fern swamp forests with persistently high groundwater tables and adjacent fluvial channel, floodplain and upland environments. The occurrence of abundant charcoal within a specific thin interval in the Cherokee Group indicates substantial wildfire ...

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

A Lithospheric Drip Triggered Green and Colorado River Integration

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract The integration of the Green and Colorado Rivers shifted the continental drainage divide of North America, marking a key event in the hydrological and biogeographical evolution of the continent. Sedimentological and stratigraphic evidence shows that for integration to occur, the Green River likely cut through the Uinta Mountains between 8 and ...

Detrital Zircon Data Support Stronger, Inland‐Tracking Hurricanes During the Miocene Climatic Optimum, Maryland USA

Paleoceanography and Paleoclimatology, Volume 41, Issue 2, February 2026.
Abstract Climate models run under warmer‐than‐modern conditions indicate that hurricanes pass closer to the US East Coast and show that a higher proportion of tropical cyclones achieve “major hurricane” strength with winds >209 km/hr. Empirical observations indicate that the dominant southward longshore current direction off the US East Coast is ...

Timing and Style of Tectonic Assembly and Exhumation of the McHugh Complex Within the Chugach‐Kodiak Accretionary Wedge, Alaska

Tectonics, Volume 45, Issue 2, February 2026.
Abstract Accretionary complexes are key archives of subduction zone processes, preserving records of forearc growth, deformation, and tectonic reorganization. The Chugach–Kodiak accretionary complex of southern Alaska records Jurassic to Cretaceous underplating at shallow to intermediate subduction conditions. The McHugh Complex, an imbricated sequence

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 ...

U/Pb Age of detrital zircons from sandstones of the upper emsian diamond takaty formation of the Western Urals

RUDN Journal of Engineering Research, 2015
The first results of U/Pb (LA-ICP-MS) dating of detrital zircons from quartz sandstones of the Devonian Takaty Formation are presented. The obtained ages span a range from 1857.5 ± 53.8 to 3054.0 ± ± 48.0 Ma.

Chemical Discrimination of Rutile From Different Metamorphic Source Rocks: Dealing With Hierarchical Data Structures in Random Forest Classification

Journal of Metamorphic Geology, Volume 44, Issue 2, Page 112-137, February 2026.
ABSTRACT Rutile provides a wealth of petrochronological information in metamorphic geology and due to its high stability during processes of the sedimentary cycle, rutile takes a special position in sedimentary provenance analysis. Besides being one of the classical minerals datable using the U–Pb system, rutile incorporates a broad range of trace ...
