Sedimentary record of submarine gravity‐flow events in the southern Ryukyu forearc during the last 200 000 years: Archive of mega‐earthquakes and tsunamis

Sedimentology, Volume 72, Issue 7, Page 2323-2360, December 2025.
ABSTRACT Despite high convergence velocity, the southern Ryukyu subduction has relatively low and sparse instrumental seismicity, in contrast with the Yaeyama Islands, hit by huge tsunamis over the last few thousand years. This study explores the potential of deep marine sediments to record past large earthquakes and tsunamis.

Fe Oxidation State and Oxygen Isotope Composition of Diverse Metasomatized Peridotite Rocks

Terra Nova, Volume 37, Issue 6, Page 403-412, December 2025.
ABSTRACT Metasomatic fluids are thought to be oxidising agents that react with the surrounding mantle rocks, causing changes in the bulk Fe3+/∑Fe, their redox state, and affecting the partitioning of trace elements and the fractionation of O isotopes. Worldwide distributed metasomatized peridotites represent the ideal case study to investigate the role

New Li Lidar Observations and Model Simulations: A Window to Anthropogenic Signatures

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract We present Li lidar observations in the mesopause region above Kühlungsborn, Germany (54°N, 12°E). The lithium layer is mainly formed by meteoric ablation. But lithium has a much higher relative abundance in space debris compared with meteoroids, making it a good indicator of anthropogenic influence in the upper mesosphere.

Boulders on Bennu: Low Apparent Thermal Inertia Caused by Thermal Fatigue Fractures

Geophysical Research Letters, Volume 52, Issue 21, 16 November 2025.
Abstract Boulders covering the surfaces of asteroids Bennu and Ryugu have apparent thermal inertias substantially lower than their meteorite analogs. This has led to the inference that boulders on Bennu may be unlike any known meteorite. However, samples returned from Ryugu have a thermal inertia 3.5 times higher than the apparent thermal inertia ...

Evaluating the Effects of Thermal Processing on Nucleosynthetic Zinc Isotope Variations: Insights from Carbonaceous Chondrites Leachates

The Astrophysical Journal
Variations in the nucleosynthetic isotope compositions of meteorites have been suggested to result from variable destruction of some presolar grains through thermal processing.
