Pre-Earthquake Oscillating and Accelerating Patterns in the Lithosphere–Atmosphere–Ionosphere Coupling (LAIC) before the 2022 Luding (China) Ms6.8 Earthquake

Remote Sensing
The coupling processes among the lithosphere, atmosphere, and ionosphere (LAI) during the earthquake preparation phase are still an open scientific debate.

Discrimination of ULF signals from an underground seismogenic current

Earth, Planets and Space
A numerical model has been elaborated to calculate ULF electromagnetic fields in the ground-atmosphere–ionosphere system created by an underground horizontal current source of a finite length.

Geophysical Coupling Before Three Earthquake Doublets Around the Arabian Plate

Atmosphere
In this study, we analysed lithospheric, atmospheric, and top-side ionospheric magnetic field data six months before the three earthquake doublets occurred in the last ten years around the Arabian tectonic plate. They occurred in 2014, close to Dehloran (

A Curie Point Depth Model of the Conterminous United States Derived From a Prior‐Constrained Equivalent Source Inversion

Geophysical Research Letters
The Curie Point Depth (CPD) is a key thermal boundary in the deep lithosphere and is widely used to constrain its thermal structure. However, uncertainties in magnetization and the non‐uniqueness of inversion lead to considerable inter‐study differences.

Solar magnetic field reversal as seen at Ulysses [PDF]

, 2003
The rapid motion of the Ulysses spacecraft from high southern to high northern latitudes in 2000–2001 provided an excellent opportunity to make inferences regarding the solar magnetic dipole's behaviour around solar maximum.

Tectonic Rift-Related Manganese Mineralization System and Its Geophysical Signature in the Nanpanjiang Basin

Remote Sensing
The southeastern Yunnan region in the southwestern Nanpanjiang Basin is one of the most important manganese enrichment zones in China. Manganese mineralization is mainly confined to marine mud–sand–carbonate interbeds of the Middle Triassic Ladinian ...

A XENOLITH-BASED LITHOSPHERIC TRANSECT OF THE SLAVE CRATON, N.W.T., CANADA [PDF]

, 2012
During the last decade, the Canadian Slave craton has emerged as an important global diamond resource. Recent work on the sub-continental lithospheric mantle (SCLM) beneath this craton has yielded tantalising suggestions about its structure and ...

Magnetotelluric sounding and electromagnetic diagnostics of the magnetosphere and lithosphere: Possibilities of complementarity

Solar-Terrestrial Physics
Observations of ultra-low-frequency (ULF) variations in geomagnetic and electrotelluric fields at a network of ground stations are the experimental basis for several geophysical areas: magnetotelluric sounding (MTS) of the earth’s crust; hydromagnetic ...

Volcanic History of Rodrigues Island and Its Relationship With the Central Indian Ridge and the Réunion Hotspot

Geochemistry, Geophysics, Geosystems
Many intraplate volcanic chains are explained as hotspot trails formed by plate motion over mantle plumes, yet some deviate from this model. The Rodrigues Ridge, a volcanic lineament extending eastward from the Réunion hotspot track toward the Central ...
