Ridge Migration and Plate Boundary Readjustments at the Rodriguez Triple Junction

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The Rodriguez Triple Junction (RTJ) marks the intersection of the Indian Ocean's three principal mid‐ocean ridges and is a type locality for Ridge‐Ridge‐Ridge triple junctions. A local seismic network was deployed for 8 months to monitor seismicity around the RTJ and the adjacent Central Indian Ridge (CIR).

Late Carboniferous Paleomagnetism From North Qiangtang Block Reveals a Multibranched Paleo‐Tethys Ocean

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The North Qiangtang Block occupies a pivotal position within the eastern Tethyan realm, and its paleogeographic reconstruction is critical for constraining Tethyan geometry and evolution. However, its Late Paleozoic paleogeography and Paleo‐Tethyan Ocean–continent configuration remain controversial due to limited reliable age‐constrained ...

Geological Mapping and Structural Analysis of the Western Half of the Eminescu Quadrangle (H09), Mercury

Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.
Abstract We present the results of the first geological mapping of the western half of the Eminescu Quadrangle (H09) on Mercury. Multiple data sets from the NASA MESSENGER Mercury Dual Imaging System instrument were used to produce a geological map covering the area between 72°E and 108°E longitude and 22.5°N and 22.5°S latitude.

An Equivalent Source Method for Modelling the Lithospheric Magnetic Field Using Satellite and Airborne Magnetic Data [PDF]

, 2014
We present a technique for modelling the lithospheric magnetic field based on estimation of equivalent potential field sources. As a first demonstration we present an application to magnetic field measurements made by the CHAMP satellite during the ...

The United States Magnetotelluric Array and the National Impedance Map

Reviews of Geophysics, Volume 64, Issue 2, June 2026.
Abstract The United States Magnetotelluric Array (USMTArray) data set, collected in the years 2006–2024, consists of more than 1,700 long‐period magnetotelluric stations covering the entirety of the contiguous United States on a quasi‐regular 70 km grid.

A model of Earth’s magnetic field derived from 2 years of Swarm satellite constellation data [PDF]

, 2016
More than 2 years of magnetic field data taken by the three-satellite constellation mission Swarm are used to derive a model of Earth’s magnetic field and its time variation. This model is called SIFMplus.

Preliminary geological interpretation of long-wavelength magnetic anomalies over China and surrounding regions

Earth and Planetary Physics
Long-wavelength (>500 km) magnetic anomalies originating in the lithosphere were first found in satellite magnetic surveys. Compared to the striking magnetic anomalies around the world, the long-wavelength magnetic anomalies in China and surrounding ...

Generation of Channelized Mantle Flow Beyond the Rift Zone Accelerated by Thermal Heterogeneity and Rift Propagation

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract Rifting is a tectonic process that leads to extensive magmatic activity, continental breakup, and the formation of new oceanic crust. The interplay between rifting and dynamic mantle flow driven by thermal heterogeneity in the mantle along the rift‐axis can influence magmatism and deformation beyond the rift zone.

The CHAOS-4 geomagnetic field model [PDF]

, 2013
We present CHAOS-4, a new version in the CHAOS model series, which aims to describe the Earth's magnetic field with high spatial and temporal resolution. Terms up to spherical degree of at least n = 85 for the lithospheric field, and up to n = 16 for the

An alternative regularization approach for modeling the regional lithospheric magnetic field from satellite magnetic measurements by the spherical equivalent source method and its application in Africa

Earth and Planetary Physics
The equivalent source (ES) method in the spherical coordinate system has been widely applied to processing, reduction, field modeling, and geophysical and geological interpretation of satellite magnetic anomaly data.
