Abstract

We display airborne gravity gradient data using curvature attributes of the equipotential surface to derive geometric shapes that can be associated with structural and geologic features. Concepts used in differential geometry that describe all geometric aspects of a surface are applied to airborne gravity gradiometry data. Gravity gradient components are ideal for this application because they are related to curvature of the gravitational potential. We also emphasize that with gravity methods, the surfaces for which the curvature attributes are derived represent the succession of equipotential surfaces, which, under favorable circumstances, correspond to one or more geologic surfaces that dominate the signature of the airborne gravity gradiometry data.
