Abstract

Using analytical formulas of the anomaly spectrums for magnetic field values along profiles parallel to the two horizontal axes of a rectangular prismatic body, a quantitative picture is obtained of the shift of the spectrum to the low frequency end with increase in either depth or horizontal dimension of the body, or in both. This constitutes a feasible method of separating effects of near-surface high-amplitude components from those of deep crustal sources in total-field aeromagnetic maps; separation of these effects, however, is not unique. The characteristics of amplitude and phase spectrums of anomalies due to prismatic bodies of different dimensions are discussed in detail.
