We present a technique for the integrated forward modelling of the three-dimensional structure and geophysical response of multiply deformed terrains. This technique allows information collected by field geologists and geophysicists to be reconciled by developing a simplified kinematic structural history of the area. The deformation history of the area is modelled using a succession of structural episodes, such as folding, shear zone activity, and intrusive events. The interaction of these episodes with a starting stratigraphy allows the prediction of the geometry of the final structures. By specifying geophysical rock properties for units in the initial stratigraphy we can also predict the potential field anomalies for gravity and magnetics. The accuracy of the model can be gauged by comparing the predictions with the observed structural and geophysical data. This approach points to a new methodology for the reconstruction of the geometry of structures in the Earth's crust, and has potential as a tool for both training and regional interpretation.
