Cooling climate across last interglacial high stands on San Salvador and Great Inagua, The Bahamas

The Depositional Record, Volume 12, Issue 1, February 2026.
Temperature data comparison with last interglacial mollusc clumped isotope data from this study, as well as from Bermuda (Minnebo et al., 2024; Zhang et al., 2021). The ‘later’ and ‘earlier’ ages within MIS 5e refer to Reef II and Reef I, respectively, for Bahamas data.

Linking palaeo‐wildfire to depositional environmental and ecological dynamics of an Early–Middle Pennsylvanian fluvial‐tidal transition zone—Palynology and pyrolysis evidence

The Depositional Record, Volume 12, Issue 1, February 2026.
The Pennsylvanian landscape in the Forest City basin was characterised by low‐lying lycopod tree and fern swamp forests with persistently high groundwater tables and adjacent fluvial channel, floodplain and upland environments. The occurrence of abundant charcoal within a specific thin interval in the Cherokee Group indicates substantial wildfire ...

Stress and Rock Failure Near Salt Bodies: Insights From Field Observations, Kinematic Modeling, and Mechanical Analysis Near Arches National Park, Paradox Basin, Utah

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract Salt's inherent weakness and capacity for ductile deformation create significant mechanical contrasts that locally perturb the stress field in surrounding rocks, often leading to deviations from regional tectonic stresses. Variations in local stress are a critical factor for wellbore stability, seal integrity, and fluid flow in subsurface ...

Multi‐Method Geochronology and P‒T Modeling Unravels the Thermo‐Tectonic History of the Rudall Province, Western Australia

Tectonics, Volume 45, Issue 2, February 2026.
Abstract The Rudall Province (RP) is a Paleo‐Mesoproterozoic belt that records numerous overprinting tectono‐metamorphic events. Situated on the eastern edge of the West Australian Craton (WAC), the RP represents a key area for understanding the Proterozoic assembly and subsequent tectonic history of Western Australia.

Lithospheric Delamination Below the North American Midcontinent Ceased Subsidence in Cratonic Basins

AGU Advances, Volume 7, Issue 1, February 2026.
Abstract Cratonic lithospheres carry a long history of tectonic modifications that result in heterogeneous structures, as revealed by an increasing number of geophysical observations. The existence of cratonic basins indicates protracted periods of tectonic modification, causing subsidence within global continental interiors.

Assessing Pb Isotopic Equilibrium Between Apatite and K‐Feldspar

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 2, February 2026.
Abstract Quantifying common Pb, the non‐radiogenic Pb present in a mineral independent of in situ U decay, is essential for obtaining accurate U–Pb ages in common Pb‐bearing minerals such as apatite. However, constraining the amount and composition of common Pb, as well as the timing of its entrapment, remains a persistent challenge.

Reconstructing Late Pleistocene to Prehistorical Holocene Geomagnetic Field Variations From La Palma Lava Flows (Canary Islands, Spain): Unraveling Viscous Components

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 2, February 2026.
Abstract We present new vector paleomagnetic data from 13 radiometrically dated lava‐flows in southern La Palma (Canary Islands) spanning from 1 to 56 ka, which covers most of the Late Pleistocene to prehistoric Holocene volcanic record in the island.

Increased Glacier Melt Across Millennia to Hours Enhances Erosion and Sediment Export Processes

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 2, February 2026.
Abstract Glacial erosion and sediment evacuation are key in shaping polar and mountain landscapes and influencing downstream ecological and social systems. The glacier dynamics and hydrology responsible for these processes are closely linked to hydrological and climatic (hydro‐climatic) conditions.
