Abstract

The evolution of the accretionary Paleoproterozoic Svecofennian orogen encompasses three evolutionary phases: accretion, plateau and collapse. During the plateau phase the upper and middle crust have been laterally spreading towards thinner areas. Several kinematic indications suggest that the collisional crustal architecture was rearranged and a new super-infrastructure was developed during lateral spreading and flow of the crust. We will show examples of post-collisional spreading with the help of seismic reflection data, seismic anisotropy maps, lineation maps, analogue models and structural observations.
