Detailed Cretaceous reconstruction model for the South Atlantic Academic Article uri icon


  • Abstract The temporal resolution of plate reconstruction models linearily depends on the frequency at which the geomagnetic field flipped its polarity. Accordingly, past plate motions during the long period of the Cretaceous normal superchron (CNS, 83.5-120.6 Ma) is poorly resolved. Recent findings on the behaviour of the geomagnetic field during the CNS (Granot et al., 2012) provide two new time markers that may be used to define internal isochrons within the Quiet zones. Here we present preliminary results of the first attempt to utilize …
