Resumen:
Transitional Jurassic and Early Cretaceous virtual geomagnetic poles (VGPs) repositioned to absolute palaeoreconstructions, define two paths similar to those for revesals of the last 12 Myr. These paths roughly coincide with the regions of the present core mantle bpundary that lie below regions of the lower mantle with fast seismic wave velocities. Absolute reconstructions of South America for the Late Permian based on these regiosn are presented.
