Late Jurassic Carbon Isotope Excursion (Middle Oxfordian Event) Paces With Astronomical Forcing in the Northwestern Tethys

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Marine carbonate carbon isotopes (δ13C), over orbital to multi‐million‐year timescales, provide critical insight into the carbon cycle connecting Earth's atmosphere, lithosphere, hydrosphere and biosphere. However, the influence of astronomical forcing on deep time carbon cycle dynamics remains poorly constrained.

Experimental Study of the Fluid Contents and Organic/Inorganic Hydrocarbon Saturations, Porosities, and Permeabilities of Clay-Rich Shale

Unlike conventional reservoirs, shale is particularly complex in its mineral composition. As typical components in shale reservoirs, clay and organic matter have different pore structures and strong interactions with fluids, resulting in complex fluid ...

Accretionary Prism and Forearc Deformation Driven by the Beata Ridge Indentation in Southern Hispaniola: Insights From the Offshore San Pedro Basin

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The Cretaceous–Eocene island arc of Hispaniola is currently shortened between the Bahamas carbonate platform to the north and the thickened crust of the Caribbean Large Igneous Province (CLIP) to the south. Within this transpressional setting, the 15–22‐km‐thick, ∼100‐km‐wide Beata Ridge (BR), the thickest portion of the CLIP, acts as a ...

Prioritizing Conservation of Trailing‐Edge Populations for Future Climate‐Resilient Forests

Global Change Biology, Volume 32, Issue 6, June 2026.
Climate change threatens warm‐ and dry‐edge tree populations that may harbor adaptive genetic variation important for future forest resilience. We identified trailing‐edge populations for frequent and widespread North American tree species using climate and forest inventory data, then prioritized conservation actions based on projected forest habitat ...

Bio‐mediated cementation of supratidal beach sediments associated with groundwater springs

Sedimentology, Volume 73, Issue 4, Page 1271-1285, June 2026.
ABSTRACT The formation of beachrock, sensu stricto, via carbonate precipitation in the intertidal zone is widespread throughout the tropics and subtropics. While cementation of supratidal beach sediments has also been noted in several locations, it has received much less attention.

Disentangling palaeoecological and outcrop controls on MISS occurrence in c. 1 Ga fluvio‐lacustrine facies of the Diabaig Formation, Scotland

Sedimentology, Volume 73, Issue 4, Page 883-913, June 2026.
ABSTRACT The c. 1 Ga Diabaig Formation of north‐west Scotland preserves diverse lacustrine and fluvial facies and abundant microbial and non‐microbial surficial sedimentary features. 172.6 m of section was logged across seven localities to assess the distribution of microbially induced sedimentary structures (MISS) relative to lithofacies, substrate ...

Microbially induced sedimentary structures in fluvial settings: the gas domes from the Bolzano Megacaldera (Permian, Italy)

Sedimentology, Volume 73, Issue 4, Page 914-944, June 2026.
ABSTRACT Gas domes serve as some of the earliest and most persisting indicators of life on Earth, yet their documentation in continental environments remains sparse. This study aims to bridge this gap by examining gas domes within the Permian fluvial succession of Monte Luco, located in the caldera of the Bolzano Supervolcano. These structures occur as

Pore Size and Wettability Control Dissolution Trapping Regimes of CO2 in Nano Porous Media

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract We simulate supercritical carbon dioxide (scCO2 ${\text{scCO}}_{2}$) dissolution in water in nano/submicron pore‐throats (14.3–21.5 nm) using a multi‐component, multiphase pseudopotential lattice Boltzmann model closed by a Peng–Robinson equation of state.
