Davie fracture zone and the movement of Madagascar
Abstract
A curvilinear feature extending over 21° of latitude can be recognised in the western Indian Ocean. Its structure and relationship to Madagascar suggest that it is a fracture zone that may have controlled the motion of Madagascar as the island drifted southwards to its present position. The pole of rotation defined by the fracture zone does not allow a good fit between the late Palaeozoic to early Mesozoic palaeomagnetic poles for Africa and Madagascar [3] if the latter was in a position against Kenya at the time. The likely presence of the fracture zone needs to be reconciled with the palaeomagnetic results.
