Figure 1. The behavior of the geomagnetic field and the plate movement rates for the last 160 Ma (a-c) and 640 Ma (d): (a) the number of the geomagnetic field reversals for 1 million years; (b) the contribution of direct magnetic polarity for 1 million years. The figures are plotted in the geomagnetic polarity time-scale [Cande and Kent, 1992], specified by E. A. Molostovskii, et al. (2004); (c) the average velocity (V) of the continental plate motion and the dispersion of the plate motion rates (dV); the averaging window is 10 million years [Jurdy et al., 1995; Pechersky, 1998]; d) the number of the geomagnetic field reversals for 10 million years [Pechersky, 1998].
