Unraveling the lithospheric magnetic field masked by the Earth’s main field by estimating the magnetization and magnetic crustal thickness using a statistical approach

Physics of the Earth and Planetary Interiors
International audienceDetailed mapping of Earth’s lithospheric magnetic field provides important insights into the composition, dynamics, and geological history of the crust.

Magnetic susceptibility anomalies of lithosphere beneath eastern Europe and the Middle East

Geophysics, 1986
Abstract Standard inversion methods for inverting aeromagnetic anomalies into magnetic susceptibility contrast in the crust are based on the assumption that the core field is constant over the region considered. This assumption, however, does not hold over regions of a few thousand kilometer extent. An inversion technique is developed

CHAMP, Ørsted, and Magsat Magnetic Anomalies of the Antarctic Lithosphere

2003
We processed CHAMP, Orsted and Magsat mission data for the Antarctic using advanced spectral correlation theory to separate spatially and temporally static components from the dynamic ones. Ignoring measurement noise and processing errors, the dynamic components include strong external field effects, whereas the static components reflect lithospheric ...

The potential contribution to long wavelength magnetic anomalies from the lithospheric mantle

Physics of the Earth and Planetary Interiors, 2019
Abstract Long-wavelength magnetic anomalies (LWMA) are broad scale variations of the magnetic field that are usually observed at high altitudes with amplitudes ranging up to about 20 nT. The source of these anomalies has typically been assumed to reside within the crust with negligible contributions from the lithospheric mantle.

Induced magnetization of the oceanic lithosphere and ocean‐continent magnetization contrast inferred from Magsat anomalies

Journal of Geophysical Research: Solid Earth, 1993
A petromagnetic forward model of induced magnetization of Iceland Plateau is presented. Magnetic susceptibilities of Icelandic rocks from the literature are placed in a vertical stratigraphic context according to a model of igneous and metamorphic layering of the Icelandic crust that is compatible with seismic and other geophysical data. Curie isotherm

Application of the data on the lithospheric magnetic anomalies in the problem of recognizing the earthquake prone areas

Izvestiya, Physics of the Solid Earth, 2016
For the first time, an attempt is made to apply the data on the lithospheric magnetic anomalies of the Earth for determining the areas prone to strong earthquakes by means of the pattern recognition algorithms. The Caucasian region with the threshold magnitude of the strong earthquakes M0 = 6 is considered.

Long wavelength magnetic anomalies from the lithosphere: Indian shield and Himalaya

Tectonophysics, 1984
Abstract A few long-range airborne magnetic profiles flown at an altitude of 7.5 km a.s.l. across the Indian shield are analysed and interpreted in terms of magnetization in the lower crust. The wavelengths of the crustal anomalies are in the range of 51–255 km and this is used to separate them from signals originating at shallow depths.

Electrical Conductivity Anomalies in yhe Australian Lithosphere: Effects on Magnetic Gradiometer Surveys

Exploration Geophysics, 1991
The use of recording magnetometers to observe natural magnetic fluctuations across different parts of Australia is delineating areas where the fluctuations are anomalous. These areas are termed 'conductivity anomalies', as the fluctuation patterns must be due to regions in the lithosphere of high electrical conductivity, where the naturally induced ...
