Abstract: A new method for regional-residual magnetic field data separation, in wavelet domain, is suggested. The method is based on the discrete wavelet transform of either 1-D or 2-D data and the same transformation of an internal model for the regional field. The separation is controlled by the transformation of the model. The effectiveness of the

Regional - residual separation is a crucial step to obtain the residual field. The expressions “residual” and “regional” are used to make a clear distinction between anomalies related to shallow and deep sources. In many cases, the choice of regional depends on the residual anomalies to be interpreted (Beltrao et al., 1991).

The magnetic field produced by the regional susceptibility model is then used as the regional field, and the residual data are obtained by simple subtraction. The advantages of this method of separation are that it introduces little distortion to the shape of the extracted anomaly and that it is not affected significantly by factors such as topography and the overlap of power spectra of regional and residual …

&#; REGIONAL RESIDUAL SEPARATION OF MAGNETIC DATA This technique was specifically designed to enhance the magnetic response of intrusive sills that occur in the coal measures. A number of anomalous zones were identified by this technique and were interpreted to be caused by the presence of intrusive sills at depth.
