Gravity data, advanced processing

Abstract

This contribution outlines the theory and practice of a number of methods for rapidly processing gravity data that are in the form of a grid. The term “processing” here includes transformations, spectral estimation and modeling, and “deconvolution” to produce depth estimates. These are all widely used methods that are equally applicable to grids of aeromagnetic data. We also introduce the continuous wavelet transform which has many potential applications in gravity processing, few of which appear to have been widely used as yet. A more extensive review of the gravity method, with comprehensive reference list, can be found in Nabighian et al. (2005).
