THE HYBRID MANTLE FRAME(250-0 Ma)

The Table above show how the Anchor Plate (Southern Africa, Plate Id. 701) is linked to the paleomagnetic/spin-axis frame (1) and to the Mantle Frame (0). The difference between the two frames is true polar wander (TPW). The hybrid mantle reference frame is using GMHRF-3 to 83.5 Ma, then a moving hotspot frame for the Indo-Atlantic to 120 Ma (Dubrovine et al., 2012; 2016), and finally a TPW-corrected longitude-calibrated (shifted 10.6°W) paleomagnetic frame before that time (Torsvik et al. 2012).
