Abstract

A formula has been derived to provide depth estimates from a greater length of the magnetic power spectrum than by using the classic Spector-Grant formula.
Consequently magnetic depths have been profiled at intervals of 5 km across the
Northern Territory for up to three bodies at each sample of grid. Shallower bodies can be located using flightline data, the ubiquitous interference being addressed by seeking coherent patches in a spread of depth estimates across space and spectrum. Ground work for real-time calculation of interference is also set out. Modelling of detailed, heterogeneous bodies is done rapidly using 3-D Fourier convolution.
