East Antarctica magnetically linked to its ancient neighbours in Gondwana
Scientific Reports, 2021 We present a new magnetic compilation for Central Gondwana conformed to a recent satellite magnetic model (LCS-1) with the help of an equivalent layer approach, resulting in consistent levels, corrections that have not previously been applied ...

Eos, Transactions American Geophysical Union, 1983 A workshop on aeromagnetic data, sponsored by the National Geophysical Data Center (NGDC) of the National Oceanic and Atmospheric Administration, was held in Boulder, Colo., November 16–18, 1982, to evaluate the requirements for a national aeromagnetic database. The following recommendations were developed by J . R.

Inland extent of the Weddell Sea Rift imaged by new aerogeophysical data [PDF]
, 2013 The Weddell Sea Rift was a major focus for Jurassic extension and magmatism during the early stages of Gondwana break-up and underlies the Weddell Sea Embayment, which separates East Antarctica from a collage of crustal blocks in West Antarctica.

Thermal Structure Beneath the Tarim Craton and Its Tectonic Implications
Frontiers in Earth Science, 2021 The lateral distribution of the magnetic layer beneath the Tarim Craton and its environs was estimated from spectral analysis using the newest high-resolution aeromagnetic dataset of mainland China, which is enlarged by EMAG2. As a proxy, the Curie point

New Magnetic compilation and interpretation of the Bay of Biscay and surrounding continental shelves
BSGF - Earth Sciences Bulletin, 2021 Producing accurate structural maps is a pre-requisite to unravel the tectonic evolution of a region. For this purpose, magnetic anomaly maps are helpful data sets for the identification and mapping of geological features.

Aeromagnetic data processing using MATLAB
IOP Conference Series: Earth and Environmental Science, 2022 Abstract This study focuses on the evaluation of magnetic field variation in a two-dimensional plot in form of a contour map by carrying out interpolation on the magnetic field data and mapping regional structures to infer the direction of dykes.

Compatibility of high-altitude aeromagnetic and satellite-altitude magnetic anomalies over Canada [PDF]
, 2002 Results from equivalent-source distributions derived jointly from high-altitude (average 4 km) aeromagnetic and Magsat-derived (average 400 km) magnetic anomalies over Canada indicate that long-wavelength components (500–2500 km) in these fields are ...
