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.

The Hematite Question: Hydrogen‐Driven Magnetization of Hematite‐Bearing Sandstones and Insights for Natural Hydrogen Exploration

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Natural hydrogen is a promising clean energy resource, but locating subsurface accumulations remains challenging. Aeromagnetic anomalies are increasingly utilized as a rapid and cost‐effective tool for geological hydrogen prospection, particularly associated with magnetite formation during abiotic geochemical hydrogen generation through ...

Geomagnetic Survey Interpolation with the Machine Learning Approach

Russian Journal of Earth Sciences, 2022
This paper portrays the method of UAV magnetometry survey data interpolation. The method accommodates the fact that this kind of data has a spatial distribution of the samples along a series of straight lines (similar to maritime tacks), which is a ...

Robust Directional Analysis of Magnetic Microscopy Images Using Non‐Linear Inversion and Iterative Euler Deconvolution

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract In paleomagnetism, bulk measurements of entire samples have traditionally been used to characterize remanent magnetization. While effective, this approach provides only a general directional estimate and cannot resolve spatial variability or magnetization at the grain scale.
