Splitting vectors for the entire Antarctic continent compiled from a variety of studies. (Kubo et al. 1995; Kubo & Hiramatsu 1998; Muller 2001; Pondrelli et al. 2004; Bayer et al. 2007; Usui et al. 2007; Reading & Heintz 2008). Results plotted from the TAMSEIS array are limited to A quality observations. Results from other studies are limited to stations with multiple high-quality observations. The grey lines represent a possible extension of Pan-African aged mobile belt into the interior of East Antarctica.
