Figure 3. Precambrian virtual geomagnetic pole positions (VGPs) from Antarctica with their 95 percent circles of confidence and ages shown after rotation of the antarctic poles around an Euler pole consistent with the SWEAT reconstruction. Abbreviations: COATS, southern Coats Land (Gose et al. 1997); BORG, Borgmassivet (Hodgkinson 1989); AHL, Ahlmannryggen (Peters 1989). Crosses indicate North American paleopoles which define the Laurentian APWP with generalized ages shown for the path. North America is shown in present-day coordinates with Antarctica and Australia restored to the SWEAT reconstruction at approximately 750 million years. The Grenville Province and its proposed continuation into Antarctica is indicated by dark shading (after Gose et al. 1997). (Ma denotes million years.)
