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.

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 ...

First scalar magnetic anomaly map from CHAMP satellite data indicates weak lithospheric field

, 2002
Satellite magnetic anomaly maps derived by different techniques from Magsat/POGO data vary by more than a factor of 2 in the deduced strength of the lithospheric magnetic field.

MEME08: A global magnetic field model with satellite data weighting [PDF]

, 2008
A new data weighting scheme is introduced for satellite geomagnetic survey data. This scheme allows vector samples of the field to be used at all magnetic latitudes and results in an improved lithospheric model, particularly in the auroral regions ...

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 ...

Macau Scientific Satellite-1 Initial Magnetic Field Model

Eight months of vector magnetic field measurements from the Macau Scientific Satellite-1 (MSS-1), supplemented by higher latitude field intensity measurements from the Swarm satellites, are used to derive an MSS-1 Initial Field Model (MIFM).

CM5: A pre-Swarm magnetic field model based upon the comprehensive modeling approach [PDF]

, 2014
We have developed a model based upon the very successful Comprehensive Modeling (CM) approach using recent CHAMP, Ørsted, SAC-C and observatory hourly-means data from September 2000 to the end of 2013.

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 ...
