Tectonic Evolution of the Mariana Trough

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract The Mariana Trough is an active back‐arc basin formed by subduction of the Pacific Plate beneath the Philippine Sea Plate and provides an ideal setting for investigating the evolution of back‐arc basins. In this study, we compile bathymetric, magnetic, and gravity data to reconstruct the formation history of the entire basin.

Cambrian Stage 3 Paleomagnetism of the South China Block: Implications for Early Paleozoic Gondwana Reconstructions

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract The paleogeographic position of the South China Block (SCB) during the early Paleozoic and its affiliation with Gondwana remain debated. We report new high‐quality paleomagnetic data from sandstone‐dominated Cambrian Stage 3 strata correlated with the Yu'anshan–Hongjingshao succession collected along the southwestern margin of the SCB ...

Décollement Rheology Controls Crustal Deformation on Early Mars

Journal of Geophysical Research: Planets, Volume 131, Issue 10, October 2026.
Abstract The circum‐Tharsis wrinkle ridge system represents one of the strongest tectonic imprints of early Mars, formed as the planet's largest volcanic province reshaped the lithosphere and redistributed stresses across thousands of kilometers. The coherent spatial pattern of these ridges suggests deformation governed by a laterally continuous basal ...

The global lithospheric field modeling based on MSS-1 and other satellites’ gradient data

Earth and Planetary Physics
We combine gradient data from the Macau Science Satellite-1 (MSS-1), CHAllenging Minisatellite Payload (CHAMP), Swarm-A, and Swarm-C satellites to develop a 110-degree lithospheric magnetic field model. We then comprehensively evaluate the performance of

Discrepancies and Transformation Between Space‐Based and Ground‐Based Dst Indices: Insights From Swarm and CSES

Space Weather, Volume 24, Issue 10, October 2026.
Abstract The Disturbance Storm Time (Dst) index is a critical metric primarily reflecting the intensity of symmetric part of the magnetospheric ring current. Although satellite magnetometry has enabled the calculation of a space‐based Dst index, such measurements exhibit a systematic bias when compared to the conventionally used ground‐based Dst. Using

Episodic Arc Behavior in an Accretionary Orogen: Insights From the New England Orogen, Eastern Australia

Tectonics, Volume 45, Issue 10, October 2026.
Abstract Detrital zircon U–Pb geochronology from Triassic–Jurassic basins in the New England Orogen (NEO) constrains sediment provenance and episodic continental arc evolution along the eastern Gondwanan margin. Dominant zircon clusters at 270–230 Ma and 340–300 Ma in these basins were likely sourced from contemporaneous magmatism in the NEO ...

A multisource geomagnetic field model incorporating ocean circulation-induced magnetic field

Earth and Planetary Physics
The movement of global ocean circulation in the Earth’s main magnetic field generates a measurable induced magnetic field (about 2 nT at geomagnetic satellite altitudes).

A Shallow‐Marine Ecosystem Before Initial Tibetan Plateau Uplift

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract The uplift of the Tibetan Plateau profoundly influences global atmospheric circulation, sediment transport, and biodiversity, but its pre‐uplift marine paleoenvironment remains poorly understood. Here we report the first discovery of an in situ benthic fossil assemblage from the Puga area in central Tibet, which was deposited on a shallow ...

Early Eocene Compressional Deformation in the Northeastern Tibetan Plateau Recorded by Magnetic Fabrics of the Longzhong Basin

Geophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Intracontinental deformation records how early Eocene India–Asia collisional stress propagated into continental interiors. How rapidly compression reached the far field, and whether coeval Paleo‐Pacific slab dynamics contributed, remain debated. The Longzhong Basin, ∼1,900 km north of the collisional zone, provides a key test.
