With the recent availability of continental-scale gravity data sets, a useful method to make regional comparisons becomes important. Isostatic gravity residuals remove unwanted crust-mantle effects from the Bouguer data and allow comparisons of large-scale geologic features, regardless of their elevation. Features such as the Andes Foreland and the Altiplano Basin can be imaged better for exploration purposes.
