Aeromagnetics

Geophysics, 1964
Abstract Many economically important mineral and petroleum discoveries can be directly or indirectly credited to the aeromagnetometer. Magnetic methods are most important for geological reconnaissance and mapping. Also, deep crustal and upper-mantle studies can be made from results. Spin-precession magnetometers, developed in the past

Study on the Aeromagnetic System between Fixed-Wing UAV and Unmanned Helicopter

Minerals (Basel, Switzerland), 2023
Based on the CH-3 and WH-110A unmanned aerial vehicle (UAV) platforms, we independently developed aeromagnetic systems for fixed-wing UAVs (FUAV) and modified unmanned helicopters (MUH), respectively.

Characteristics of the crystalline basement beneath the Ordos Basin: Constraint from aeromagnetic data [PDF]

Geoscience Frontiers, 2015
Aeromagnetic anomaly zonation of the Ordos Basin and adjacent areas was obtained by processing high-precision and large-scale aeromagnetic anomalies with an approach of reduction to the pole upward continuation.

Optical Filtering of Aeromagnetic Maps

Applied Optics, 1974
An optical processor has been used to filter aeromagnetic contour maps in order to obtain information on underground magnetic ore deposits. This was accomplished by directional filtering of the spatial Fourier transform of the contour map. The directional filtering yields maps of gradients having given directions.

Aeromagnetic Gradiometry And Compensation

5th SAGA Biennial Conference and Exhibition, 1997
Although the concepts of aeromagnetic gradiometry are not new, it is only in the past several years, with a handful of gradient-equipped aircraft becoming operational, that the benefits are being realized. The main applications to date are the following: • In a total field survey, a lateral gradiometer provides additional information about the field ...

Aeromagnetics with an Unmanned Airship

Proceedings, 2013
Unmanned aerial vehicles (UAVs) have a growing field of applications. Geomagnetic measurements in difficult terrain are one example where UAVs can be a useful tool. So far only a few case studies about ultra-light UAVs have been published. Most of them are based on the principle of rotary wings, e.g. helicopters or multicopters. The payload capacity of

Skeletonization of aeromagnetic data

Geophysics, 2004
Abstract Skeletonization is a syntactic pattern-recognition method that is applied to gridded data to produce an automatic line drawing, with an associated event catalog. Previous implementations of skeletonization have been tailored for seismic data. Here, we modify that technique to render it more suitable for other types of gridded

Aeromagnetics in Exploration: ABSTRACT

AAPG Bulletin, 1983
Uses for aeromagnetic surveys include the evaluation of prospect leads and prospects that are controlled by basement fault movements. The identification of basement faults is based on the interpretation of the significance of magnetic edges. Magnetic edges are of two general types: (1) contacts between rock types within the basement, and (2) faults on ...
