Velocity modeling and prestack depth imaging by GX Technology (GXT) show a previously unrecognized deformation mechanism in the area of our test lines, south-southwest of Sable Island. Shale, not salt, tectonics dominates the deformation of the late Cretaceous and Tertiary section on the upper to mid slope in this area.
A layer that resembles an allochthonous salt sheet results in the formation of minibasins1 and structural highs. However, the distinctively lower velocities indicate tha...
