“…The results are signals represented by "plateaus". Signum Transform outlines well borders of dykes and structures well, as it is practically independent of the sources' depth (Souza & Ferreira, 2012, 2015.…”

“…The causative source will have the value +1. It was suggested to use first-order vertical derivative of the magnetic anomaly, second-order vertical derivative or first-order vertical derivative minus total horizontal derivative as filtering function (Souza & Ferreira, 2015). Signum transform of second-order vertical derivative has given better results in this study.…”

“…However, like the TDR, this method depends on the inclination of magnetic field. Signum transform (ST) suggested by Souza and Ferreira (2015) is a simple derivative-based method for qualitative and quantitative interpretation of magnetic anomalies from dyke-like structures. The method is based on the normalization the filtering function by its absolute value.…”

“…For any magnetic anomaly M, which could be the firstor second-order vertical gradient or subtracting the total horizontal gradient from the first-order vertical gradient [33] as expressed in equation (5), the zeros should ideally be at a ± ;…”
