High‐Fidelity Cretaceous‐Paleogene Boundary Investigations: Records of Impact and Transport

Geochemistry, Geophysics, Geosystems, Volume 26, Issue 10, October 2025.
Abstract The Chicxulub impact on the Yucatán Peninsula triggered the end‐Cretaceous mass extinction 66 million years ago, but physical models still struggle to accurately describe ejecta generation and transport from this and other large meteorite impacts. To better constrain these processes, Kaskes et al.

Quantifying Serpentinization‐Driven Remagnetization From Ridge Axis to Subduction Zone Using Quantum Diamond Microscopy

Journal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract Diachronous ferromagnetic (sensu lato) mineral populations are often juxtaposed on micrometer‐to‐millimeter scales. This poses significant challenges for extracting reliable paleomagnetic information because standard methods measure bulk magnetic moments and cannot distinguish between magnetic minerals with overlapping demagnetization spectra.

Elastic Properties of Returned Samples From Asteroid (162173) Ryugu

Journal of Geophysical Research: Planets, Volume 130, Issue 10, October 2025.
Abstract The successful sample return from asteroid (162173) Ryugu by Hayabusa2 has contributed to our understanding of the solar system evolution. Over the course of the initial sample analysis, various measurements were conducted, such as mineralogical observation, chemical analysis, and mechanical property measurement.

Calcite Marbles as Records of Episodic Deformation During Exhumation of High‐Pressure Rocks (Syros Island, Aegean Region)

Tectonics, Volume 44, Issue 10, October 2025.
Abstract We present new calcite microstructural, petrofabric, and grain size data from high‐pressure marbles, integrated with microstructural observations from associated greenschist‐facies rocks, to investigate spatio‐temporal variations in deformation intensity during the exhumation of the Cycladic Blueschist Unit in southern Syros Island (Cycladic ...
