Confirmation of the impact origin of the Late Ordovician Tvären impact structure (southeast Sweden) and emplacement of impactites in a marine setting

Meteoritics &Planetary Science, Volume 61, Issue 7, Page 1188-1212, July 2026.
Abstract The Tvären structure in southeastern Sweden has been listed as a confirmed marine‐target impact structure for decades. However, to date, no measurements and/or indexed data of planar deformation features in quartz grains from the structure have been published or any other unequivocal evidence of impact.

Unusual occurrence of Cochlichnus in aeolian sandstones: evidence for a stiletto fly larval origin

Papers in Palaeontology, Volume 12, Issue 3, May/June 2026.
Abstract Cochlichnus anguineus is an ichnotaxon recognized for its distinctive regular wavy morphology. It is a characteristic trace fossil typically associated with aquatic and marginal aquatic environments. However, in this study we examine its unusual occurrence in the aeolian sandstones of the Botucatu Formation (Lower Cretaceous, Paraná Basin ...

The Dissipation Regime of Turbulence on Mars Observed With Microphone Data From the Mars 2020 Perseverance Rover

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Turbulent winds are a regular occurrence in planetary boundary layers. Turbulence affects mixing, energy fluxes and forcing on the surface environment. Energy injected into an atmosphere generates eddies of many scales down to a size where molecular viscous forces dominate, termed the Kolmogorov length scale.

Palagonitization of Volcanic Rocks in Polar Climates: The Case of Deception Island (Antarctica)

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 12, December 2025.
Abstract A detailed study of palagonitization in rocks from Deception Island—one of Antarctica's most active volcanoes—has been performed to advance our understanding of this alteration process. A detailed petrographic (optical and SEM), mineralogical (XRD), and mineral and glass spot geochemistry (EDS and EMP) characterization has been conducted on ...

Dust, Sand, and Winds Within an Active Martian Storm in Jezero Crater

Geophysical Research Letters, 2022
Rovers and landers on Mars have experienced local, regional, and planetary‐scale dust storms. However, in situ documentation of active lifting within storms has remained elusive.
