Inversion of regional gravity gradient data over the Vredefort Impact Structure, South Africa

We present the results for 3D inversion of gravity gradiometry data over the Vredefort Impact Structure in South Africa. With the rapidly growing field of gravity gradiometry, an investigation into the extraction of information from multiple components is warranted. Though the gradient tensor has five independent components, any combination of the components can be used to invert for a structural representation of the subsurface. In an effort to understand how differing component combinations contribute to the resolution of the model, we use two measured and one calculated gravity gradient component from the Falcon system for inversion. This inquiry focuses on regional geologic features in the context of inversion with select gravity gradient components over the Vredefort impact structure in South Africa.
