Forward modeling of three-dimensional geological and potential-field data

In this paper we present the basis for an integrated geological and geophysical modeling system (Noddy), together with the results of modeling poly-deformed terrains from Australia. The modeling system produces three-dimensional models of geological structures resulting from the imposition of a sequence of deformation events, and subsequently calculates potential-field anomalies for these structures. The integration of geological and geophysical modeling allows both the generation of internally consistent geological models and also the modeling of complex geophysical behaviour, such as remanence vectors deflected around fold hinges. An atlas of the potential-field response of common structural settings is being developed in conjunction with this project, examples from which will be shown.
