Anomaly crust fields from MAGSAT satellite measurements:their processing and interpretation

open access: yesAnnals of Geophysics, 2004
The space distribution of the magnetic anomaly field for the Pacific Ocean is obtained from data of the satellite MAGSAT. A number of long-wavelength magnetic anomalies of the region are identified. A spectrum analysis of a number of profiles of the

Reverse magnetic anomaly controlled by Permian Igneous rocks in the Iberian Chain (N Spain) [PDF]

open access: yesGeologica Acta, 2014
Two important reverse dipolar magnetic anomalies in the Iberian Chain (Spain) are located over Permian igneous rocks. A detailed study of one of them, the Loscos magnetic anomaly, where the geological structure is well constrained, reveals that the ...

A new magnetic anomaly map for Greenland based on a combination of equivalent source modeling and spherical harmonic expansion [PDF]

open access: yesEarth System Science Data
The Greenland Magnetic Map (GREENMAG) is a new compilation of magnetic anomaly data that covers the inland ice, ice-free coastal areas, and adjacent shelf regions of Greenland (https://doi.org/10.22008/FK2/LQN5YJ, Heincke and Szwillus, 2025). GREENMAG is

Joint analysis of the magnetic field and total gradient intensity in central Europe [PDF]

open access: yesSolid Earth, 2019
In the European region, the magnetic field at satellite altitudes (∼350 km) is mainly defined by a long-wavelength magnetic low, called the Central European Magnetic Low (CEML) here, located to the southwest of the Trans-European Suture Zone (TESZ)

Crustal magnetization and long‐wavelength aeromagnetic anomalies of the Minto block, Quebec [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 1999
Measured susceptibilities of >3500 samples from a 500×500 km area of the Minto block, Superior province, Quebec, have an average value of ∼0.03 SI (equivalent to induced magnetizations of ∼1.5 A/m). Charnockitic lithologies (igneous orthopyroxene‐bearing granodiorite, granite, diorite), that constitute large parts of the Minto region, yield the ...

Compatibility of high-altitude aeromagnetic and satellite-altitude magnetic anomalies over Canada [PDF]

open access: yes, 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 ...

Constraint on primordial magnetic fields in the light of ARCADE 2 and EDGES observations

open access: yesEuropean Physical Journal C: Particles and Fields, 2021
We study the constraints on primordial magnetic fields (PMFs) in the light of the Experiment to Detect the Global Epoch of Reionization Signature (EDGES) low-band observation and Absolute Radiometer for Cosmology, Astrophysics and Diffuse Emission ...

Rock magnetic properties of the Arunta Block, Central Australia, and their implication for the interpretation of long‐wavelength magnetic anomalies [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 1993
Rock magnetic and petrologic studies of a suite of deep crustal rocks from the Arunta Block of Central Australia reveal that the granulite grade rocks are in general much more magnetic than the amphibolite grade samples irrespective of bulk rock composition.
