In this abstract it is shown how to apply the Tilt-Depth and Contact-Depth Methods to magnetic anomalies from thin dykes. Instead of using the derivatives of the magnetic field the method uses its Hilbert transform. The method is thus less sensitive to noise than the Tilt-Depth and Contact-Depth methods.
