Magnetic Anomaly
Linked via "Euler Deconvolution"
Spectral Analysis and Depth Estimation
The geometry of an anomaly provides clues to the depth of its causative body. Deeper sources generally produce broader, lower-amplitude anomalies with smoother transitions than shallow sources. Mathematical techniques, such as Euler Deconvolution or spectral analysis, are routinely employed to estimate the optimal depth ($z$) of the magnetic sources.
A foundational concept in this analysis relates the half-width ($\omega_{1/2}$) of a magnetic anomaly to the depth ($z$) of a simple, ver…
