Sensitivity analysis of the lithospheric magnetic field at satellite altitude: the effects of the inducing field and the shape of the magnetic lithosphere

Earth and Planetary Physics
As a means of quantitative interpretation, forward calculations of the global lithospheric magnetic field in the Spherical Harmonic (SH) domain have been widely used to reveal geophysical, lithological, and geothermal variations in the lithosphere ...

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 ...

The CHAOS-7 geomagnetic field model and observed changes in the South Atlantic Anomaly

Earth, Planets and Space, 2020
We present the CHAOS-7 model of the time-dependent near-Earth geomagnetic field between 1999 and 2020 based on magnetic field observations collected by the low-Earth orbit satellites Swarm, CryoSat-2, CHAMP, SAC-C and Ørsted, and on annual differences of

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.

Thermal evolution of the North Atlantic lithosphere: New constraints from magnetic anomaly inversion with a fractal magnetization model [PDF]

Geochemistry, Geophysics, Geosystems, 2013
Using recently published global magnetic models, we present the first independent constraint on North Atlantic geothermal state and mantle dynamics from magnetic anomaly inversion with a fractal magnetization model. Two theoretical models of radial amplitude spectrum of magnetic anomalies are found almost identical, and both are applicable to detecting

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.

On the precursors to the 2011 Tohoku earthquake: crustal movements and electromagnetic signatures

Geomatics, Natural Hazards & Risk, 2016
We compare the precursory behaviour of crustal movements with electromagnetic signatures for the 2011 off the Pacific Coast of Tohoku earthquake. First, we present the Global Positioning System (GPS) data on the co-seismic variations and pre-seismic ...

Geochemical and Isotopic Constraints on Long‐Lived Source Enrichment and Mantle Evolution in Paleoproterozoic Cratonic Lamprophyres

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 6, June 2026.
Abstract The cratonic lithospheric mantle records complex metasomatic processes and is frequently tapped by alkaline magmatism, offering a unique opportunity to trace the progressive evolution of the mantle. In the present contribution, we investigate a newly identified calc‐alkaline lamprophyre field from the Neoarchean Jonnagiri Schist Belt, Eastern ...

A high-resolution lithospheric magnetic field model of China and surroundings by using CHAMP, Swarm, CSES-1, and MSS-1 satellite magnetic measurements and aeromagnetic anomaly data

Earth and Planetary Physics
The CUG_CLMFM3D series comprises high-resolution three-dimensional lithospheric magnetic field models for China and its surroundings. The first version, CUG_CLMFM3Dv1, is a spherical cap harmonic model integrating the WDMAMv2 (World Digital Magnetic ...
