Determination of Conrad and Curie point depth relationship with the variations in lithospheric structure, geothermal gradient and heat flow beneath the central main Ethiopian rift [PDF]
Heliyon, 2022 Spectral analysis of the pole reduced magnetic anomaly data and inversion of complete Bouguer anomaly data are employed here as there is no previous published data regarding for the determination of the Curie point depth (CPD), Conrad depth (CD) and ...

A 2D Lithospheric Magnetic Anomaly Field over Egypt Using Gradient Data of Swarm Mission
Universe, 2022 The current work makes use of the geometrical configuration of the two lower-altitude Swarm satellites (Swarm A and C), moving side by side with a longitudinal distance of 1.4°, to estimate a two-dimensional (2D) model of the lithospheric magnetic ...

Lithospheric long-wavelength magnetic anomalies and their geological origins: A review
地球与行星物理论评At the altitude of low-Earth-orbiting satellites, most details of lithospheric magnetic anomalies observed near surface are attenuated, and only slowly decaying long-wavelength magnetic anomalies can be detected.

A high-resolution lithospheric magnetic field model over southern Africa based on a joint inversion of CHAMP, Swarm, WDMAM, and ground magnetic field data [PDF]
Solid Earth, 2018 We derive a lithospheric magnetic field model up to equivalent spherical harmonic degree 1000 over southern Africa. We rely on a joint inversion of satellite, near-surface, and ground magnetic field data.

Ørsted verifies regional magnetic anomalies of the Antarctic lithosphere [PDF]
Geophysical Research Letters, 2002 Initial magnetic measurements from the Ørsted satellite reveal lithospheric anomalies over the Antarctic that are similar to those obtained by Magsat. Accordingly, lithospheric anomalies can be extracted from the Ørsted data, despite the much greater operational altitude of Ørsted (650–865 km) relative to Magsat (350–550 km).
