Abstract

This paper presents a technique for the integrated forward modelling of the structure and geophysical response of multiply deformed terranes. This technique allows information collected by field geologists and geophysicists to be reconciled by the development of a simplified structural history of the area. The modelling is based on the deformation history of the area, in terms of a succession of structural events, such as folds, shear zones and intrusions. The interaction of these events with an assumed stratigraphic model results in the prediction of feasible structures. By specifying rock properties for the units in the initial stratigraphy, predictions can also be made as to the potential field anomalies for gravity and magnetics. The accuracy of the model can be gauged by comparing the predictions with the constraints provided by 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 research and training.
