This paper describes an investigation of the use of aeromagnetic crossover misfits as a source of geological information. The misfits occur when, at a crossover point of an aeromagnetic survey, the separate measurements of the Earth’s magnetic field are not the same. Misfits are mainly the result of time-dependent field changes and, in this paper, are analysed as indicators of electromagnetic i...

A high-resolution aeromagnetic survey over the Cape Roberts Rift Basin: Correlations with seismic reflection and magnetic susceptibility log data" (2007). Related Publications from ANDRILL Affiliates. Paper 21. Summary A high-resolution aeromagnetic survey (altitude 125 m asl, spacing 500 m , area 800 km 2) was carried out in 1994 offshore of Cape Roberts by the GITARA (German ITalian Aeromagne...

Quantitative analysis of geoscientific data to determine the areas most likely to contain mineral deposits is becoming increasingly common in the mining industry. The approach is based on characterising areas known to contain deposits and seeking similar areas elsewhere. This paper presents an automatic image processing technique for the prospectivity analysis of Archaean lode gold deposits, wh...

Frequency is a key physical parameter in potential field theory. Accordingly, Fourier transforms play an important role in aeromagnetic processing and many common enhancements are efficiently implemented in the Fourier domain. However, the trade-off for accurately measuring the frequency content of a signal is a complete absence of spatial localisation in the Fourier domain. Fourier-based enhan...

Every day, mining corporations grow and develop over Egypt’s Eastern Desert in search of gold, silver, other metals. Mineral resources Egypt are a powerful tool for increasing national income. In this study, we interested mineral exploration, such as gold porphyry deposits, using aeromagnetic data, applying various processing techniques First Vertical Derivative, Total Horizontal Gradient, Anal...

By analysing potential field data in the wavelet domain and performing a multi scale edge detection we can automate what is commonly called 'worm analysis', i.e., the traditional visual inspection of gravity and aeromagnetic data in order to detect shallow faults, lineaments, contacts etc. More importantly, with the use of an appropriate wavelet, defined by the physics of the problem, informati...
