“…He argued that the subsequent behaviour of the plate was affected by a change in the structure of convective cells in the mantle. However, his arguments were based on old palaeomagnetic data, and the interpretation seems unlikely because it conflicts with the modern forward drift of the EAP and available palaeomagnetic data from the Siberian and Kazakhstan blocks, which indicate long-term clockwise rotation before the Permian (Filippova et al, 2001;Sennikov et al, 2004;Smethurst et al, 1998;Van der Voo, 1988). Hence, it is not quite correct to consider the drift of the EAP as historically inherited (Zemtsov, 2007).…”
