AbstractThere is significant correlation between the tectono-stratigraphic record in the sedimentary basins round the Central North Atlantic and the seafloor spreading history of the North Atlantic. This has been taken as an indication that the formation of these basins can be related to the relative motion between lithospheric plates. Based on many criteria, plate kinematics of the North Atlantic have been derived for the rifting periods of these basins. Reconstructions of the North Atlantic based on these plate kinematic solutions show a progressive overlap between the reconstituted plate boundaries. These overlaps exist because the margins of the original plates stretched during rifting: present-day plate boundaries are therefore extended beyond their pre-rift locations. From the overlaps, it is possible to calculate the amount of extension during rifting and to restore the plates and their enclosed basins to their pre-stretched configurations. The paper discusses techniques for the de-stretching of plate margins and describes a set of reconstructions showing the configuration of these basins as they evolved. For the first time, the reconstructions give a pictorial presentation of the formation of these basins.
