oa Towards Dynamic Restoration of Geologic Profiles

Restoration aims to achieve geometric consistency and kinematic compatibility between deformed and restored sections. Normal restoration does not take account of dynamics. Dynamic restoration requires achieving not only accurate geometric and kinematic restoration, but also requires that account be taken of strain variations (e.g. layer parallel shortening) with depth and due to the different rheological properties of the deformed units and material flow in and out of the restored profile. Models of compresional regimes (accretionary wedges) and salt structures are used to illustrate the significance of layer-parallel shortening and three-dimensional flow of material in dynamic restoration.
