A review on the analysis of aeromagnetic anomaly and its geological and tectonic applications

地球与行星物理论评, 2022
Aeromagnetic anomaly has the obvious advantages of wide coverage, low cost and high lateral resolution in geological structure research, and has been widely used in concealed magmatic rock and faults detection, tectonic characteristics (e.g.

Analysis of Acoustic–Magnetic Fields Induced by Underwater Pressure Wave in a Finite-Depth Ocean

Remote Sensing, 2023
As underwater disturbances (natural or artificial) occur in the ocean, moving seawater crossing the geomagnetic fields will produce weak circular currents.

Technical procedures for aeromagnetic surveys in Antarctica during the Italian expeditions (1988-1992)

Annals of Geophysics, 1994
For most of Antarctica, the geophysical data now available are those of aeromagnetic surveys performed there from 1950 to 1960. Until 1984, the inaccurate positioning and insufficient monitoring of geomagnetic time variations allowed the investigation of

The Estimation of Magnetite Prospective Resources Based on Aeromagnetic Data: A Case Study of Qihe Area, Shandong Province, China

Remote Sensing, 2021
In the Qihe area, the magnetic anomalies caused by deep and concealed magnetite are weak and compared with ground surveys, airborne surveys further weaken the signals. Moreover, the magnetite in the Qihe area belongs to a contact-metasomatic deposit, and

High-Precision Source Positions Obtained by the Combined Inversion of Different-Order Local Wavenumbers Derived from Aeromagnetic Data

Remote Sensing, 2022
The aeromagnetic survey is a common remote sensing tool for detecting iron deposits. The local wavenumber of a magnetic anomaly is used to interpret the edges or positions of the sources, and can involve first- or second-order local wavenumbers.
