Lithospheric long-wavelength magnetic anomalies and their geological origins: A review

地球与行星物理论评
At the altitude of low-Earth-orbiting satellites, most details of lithospheric magnetic anomalies observed near surface are attenuated, and only slowly decaying long-wavelength magnetic anomalies can be detected.

An Ediacaran Metasedimentary Fragment With Northern Gondwana Affinity in the Southern East Kunlun Accretionary Belt, Northern Tibetan Plateau: Implications for the Dispersal of Peri‐Gondwanan Terranes

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract Precambrian supercontinent reconstructions largely rely on robust geological constraints. Among these, the basin affinities recorded by Precambrian sedimentary fragments preserved in orogenic belts provide critical evidence for resolving the paleogeographic configurations of microcontinents and continental blocks.

A Time‐Continuous Model of the 3D Ionospheric Current System and Associated Magnetic Fields in the Diurnal Variation Band

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract Ionospheric currents and their associated magnetic perturbations are difficult to predict due to the high variability of their driving mechanisms. In addition, the 3D structure of the currents is challenging to unravel due to the lack of direct observations within the current flow region, particularly in the E $E$‐layer.

Nighttime Westward Equatorial Electrojet Observed During the January 2026 Geomagnetic Storm

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract The equatorial electrojet (EEJ) is a narrow band of zonal electric current flowing in the E‐region ionosphere within approximately ±2° $\pm 2{}^{\circ}$ latitude of the magnetic equator. At night, the EEJ is generally considered very weak because of low ionospheric conductivity.

A Global Lithospheric Magnetic Field Model Derived From Multi‐Satellite Gradient Observations and Regional Aeromagnetic Data

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 10, October 2026.
Abstract Using gradient data from the Macau Science Satellite‐1 (MSS‐1), CHAMP, Swarm‐A, and Swarm‐C satellites, together with aeromagnetic model data from China, we built the China‐specific Global Gradient Lithospheric Magnetic Model (CGGLM). The new model reaches spherical harmonic degree 140 and uses the Iteratively Re‐weighted Least‐Squares method ...

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 ...

Advancements in low Earth orbit satellite magnetic field measurements and global geomagnetic field modeling

地球与行星物理论评
Low Earth orbit (LEO) satellites have emerged as a primary tool for global geomagnetic field detection and model refinement, owing to their wide coverage, high resolution, and absence of geographical limitations.

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
