Detailed mapping of the Earth's lithospheric magnetic field provides key constraints on the composition, dynamics and history of the crust. This field can be mapped using satellite and near-surface measurements to build a model over a wide range of spherical harmonics.

Co-estimation of core and lithospheric magnetic fields by a maximum entropy method
Geophysical Journal InternationalSUMMARY Satellite observations of the geomagnetic field contain signals generated in Earth’s interior by electrical currents in the core and by magnetized rocks in the lithosphere. At short wavelengths the lithospheric signal dominates, obscuring the signal from the core. Here we present details of a method to co-estimate separate models

Correlation of Gravity and Magnetic Field Changes Preceding Strong Earthquakes in Yunnan Province
Applied Sciences, 2022 The annual variation trend of the gravity and lithospheric magnetic field for adjacent periods are analyzed by using the observation of rover gravity and geomagnetic fields in Yunnan from 2011 to 2021, which tend to be consistent every year during the ...

Tracing Recycled Crustal Materials in the Subcontinental Lithospheric Mantle Using Thallium Isotopes
Geophysical Research Letters, 2022 Here we report the first set of thallium (Tl) isotope data in alkaline rocks from the North China Craton to constrain the nature of recycled materials in the metasomatized subcontinental lithospheric mantle.

The Magnetic Field of the Earth's Lithosphere: The Satellite Perspective [PDF]
Eos, Transactions American Geophysical Union, 1999 During the planning stages of the World Magnetic Survey in the early 1960s, geologists and geophysicists had no inkling that crustal magnetic anomalies might one day be observed from space. The appearance of The Magnetic Field of the Earth's Lithosphere: The Satellite Perspective is a welcome testimony to how far that science has advanced.

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 ...
