Kinematics of Burial Remagnetizations in Fold‐and‐Thrust Belts: A Case Study From the South Pyrenean Foreland Basin (NE Spain)

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract This study investigates two burial‐related remagnetizations in the Jaca–Pamplona foreland basin (Southern Pyrenees): one with dual polarity and a positive reversals test, and another with only reverse polarity. These components, labeled C3 and C4 based on their mean unblocking temperatures, were identified from a paleomagnetic analysis of 142 ...

Using Terrestrial Organic Matter to Reconstruct the Stable Carbon Isotope Composition of the Atmosphere

Paleoceanography and Paleoclimatology, Volume 41, Issue 4, April 2026.
Abstract Carbon fluxes to Earth's atmosphere are reflected in the carbon isotope composition of atmospheric CO2 (δ13Catm). δ13Catm is used to track past changes to the global carbon cycle and is a variable in many paleoclimate proxies. However, existing δ13Catm proxy records derived from marine carbonates are relatively low‐resolution prior to the ...

Extent and character of early tertiary penetrative deformation, Sonora, Northwest Mexico [PDF]

Reconnaissance field work has led to the recognition of extensive Early Tertiary gneiss and schist which are distinguished by weakly developed to highly conspicous northeast to east-trending stretching lineation commonly accompanied by low-dipping ...

Evolution of the East Antarctic Ice Sheet Since Glacial Inception From Seismic Stratigraphic Records in Vincennes Bay

Paleoceanography and Paleoclimatology, Volume 41, Issue 4, April 2026.
Abstract Seismic reflection data from Vincennes Bay, East Antarctica, provide the first insights into the Cenozoic evolution of the East Antarctic Ice Sheet (EAIS) in the Knox Coast. Long‐distance seismic horizon correlation allows age estimates for the seismic stratigraphic framework constructed for the continental shelf.

Rotation in the Southeastern Caribbean Arc (Grenadines) Accommodated by Back‐Arc Basin Inversion

Tectonics, Volume 45, Issue 4, April 2026.
Abstract The Caribbean tectonic plate is typically modeled as a rigid plate moving along discrete plate boundaries. Isolated exposures on islands have long shown that above the Lesser Antilles subduction zone, the plate experienced contractional, strike‐slip, and extensional deformation, but the importance of this deformation remained long unknown ...

Spatial and Temporal Evolution of Graben Formation During Rift Linkage Using Quantitative Geomorphology: Insights From Central Afar

Tectonics, Volume 45, Issue 4, April 2026.
Abstract Quantifying fault slip rates and resolving rift segment linkage mechanisms is important for understanding the evolution of magma‐rich rift systems and the broader processes of continental break‐up. In tectonically and volcanically active rifts, such as Afar, there is commonly a lack of quantitative, observational constraints on long‐term fault
