Enhancing event stratigraphic correlations in the ultra‐deep Japan Trench using XRF‐CS cluster‐based chemostratigraphy

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
Cluster‐based chemostratigraphy using XRF‐CS enables high‐resolution correlation of event deposits across contrasting depositional settings in the Japan Trench. This approach reveals previously unrecognised events and compositional heterogeneity, offering new insights into sediment provenance and earthquake‐triggered deposition, with implications for ...

Orbital and eustatic control of basin hydrology during the first stage of the Messinian Salinity Crisis

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
The paleo‐hydrology of the Sorbas Basin (SE Spain) and the wider Mediterranean region during the deposition of the Primary Lower Gypsum (PLG) stage of the Messinian Salinity Crisis, from ~5.97 to ~5.60 Ma, was affected by tectonics, precession‐forced climate oscillations, and eustatic sea‐level change.

Michel Serres: From restricted to general ecology [PDF]

open access: yes, 2017
Michel Serres's relation to ecocriticism is complex. On the one hand, he is a pioneer in the area, anticipating the current fashion for ecological thought by over a decade.

A critical role of heterotrophic bacteria in early diagenesis of carbonates through exopolymer degradation and calcium release

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
Exopolymeric substances (EPS) produced in the photic zone and surface sediments sequester calcium. Below the sediment surface, heterotrophic bacteria degrade EPS, releasing calcium resulting in carbonate precipitation. This process, which continues for millennia deep in the core, is an important sink for atmospheric carbon dioxide.

Microbial mediation and climatic control on dolomite precipitation in a hypersaline lake: Insights from Salinas Lake, southern Iberia

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
The cyclical nature of aridity and humidity led to the alternating deposition of dolomite‐rich and calcite‐rich sediments. During arid phases, the lake hydrology and growth of microbial mats under evaporative and hypersaline environment favors the precipitation of dolomite.

Silicate and Carbonate Weathering Perturbation at the Eocene‐Oligocene Transition Recorded by Mg Isotopes

open access: yesGeochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract During the Eocene‐Oligocene Transition (ca. 34 Ma), the Earth underwent a dramatic decline in atmospheric CO2, global cooling, a deepening of the carbonate compensation depth (CCD), and the formation of a permanent ice sheet on Antarctica. The expansion of Antarctic glaciers eroded the underlying bedrock and increased the weathering flux to ...

Slab‐Mantle Interaction During Subduction Initiation: Constraints From Trace Element and Sr‐Nd‐Pb Isotope Systematics of Boninite and Other Magmas and Metamorphic Sole in the Oman Ophiolite

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract The Late Cretaceous Oman ophiolite includes a series of volcanic rocks generated during the transition from spreading ridge to protoarc associated with subduction initiation. We analyzed major and trace elements and Sr, Nd, and Pb isotope compositions of lavas and dikes of the protoarc stage, especially boninites. We also analyzed amphibolites

Difference in Slip Patterns Between Two Prehistoric Giant Earthquakes Along the Southern Kuril Trench

open access: yesGeophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract This study reveals different slip patterns of tsunami sources between two prehistoric giant earthquakes along the southern Kuril Trench, based on an integration of geological data and numerical simulations. The most recent giant earthquake occurred in the 17th century and its predecessor was in the 13th–14th century.
