Abstract

This paper presents a multi-deconvolution method for interpretation of potential-field data. The multi-deconvolution method used information from isolated anomalies and data transformations to produce functions forming a peak or a through above the center of a potential-field source. The proposed method can be applied to a wide range of potential field anomaly data as well as their total gradient (TG) and local wavenumber (LW) data. It allows the determination of the source depth and physical property of the source (susceptibility or density) from potential field data or their TG data if one assumes a source type. When applied to the local wavenumber of potential field data, it does not require information about the type of the source. Instead it enables the determination of both the depth and information about the nature of the source. The potential advantages of the method to estimate source parameters from gravity and magnetic data are illustrated using theoretical and field examples. The practical utility of the method is demonstrated using high-resolution data over dike-like bodies from Egypt.
