“…The possibility that the Grenville-age grains are recycled from the Neoproterozoic Brigham Group of southeast Idaho is rejected because there are thick Cambrian and younger strata overlying the group (Yonkee et al, 2014), rather than an unconformity to Permian rocks, as would be expected if it had been uplifted in Pennsylvanian time.…”

“…After the early Cambrian appearance of the Transcontinental Arch, which blocked transport of sand grains from eastern Laurentia, detrital zircon age populations in western North America show eastern and southern derivation from the Paleoproterozoic and Mesoproterozoic (1800-1650 and 1500-1400 Ma, respectively) YavapaiMazatzal provinces in Cambrian and Devonian time and the Paleoproterozoic (>1800 Ma) Peace River Arch in Alberta, Canada, in Ordovician time (Ketner, 1968;Smith and Gehrels, 1994;Gehrels et al, 1995;Balgord et al, 2013;May et al, 2013;Gehrels and Pecha, 2014;Yonkee et al, 2014). After the Late Devonian, 1250-950 Ma detrital zircons from the complex Grenville Orogen are present in sandstones of the thrust belt, having been recycled through the Appalachian (e.g., Gehrels et al, 2011) and/or Ellesmerian-Caledonian orogenic belts (e.g., Patchett et al, 1999Patchett et al, , 2004Beranek et al, 2010).…”

“…Overall, its first-order rifting history seems to consist of two major phases (Figure 5a). The second phase of dislocation started along the eastern margin of Laurentia, WAC-Amazonia, and Baltica from around 620 to 530 Ma (Aleinikoff et al, 1995;Cawood et al, 2001;Colpron et al, 2002;O'Brien & van der Pluijm, 2012;Prave, 1999;Yonkee et al, 2014).

Large polar motions are observed in the apparent polar wander paths of several continents during the Ediacaran. Among various hypotheses proposed in the literature, one consists of the occurrence of two successive fast and large true polar wander (TPW) episodes, from 615 to 590 Ma and then between 575 and 565 Ma. In this study, we explored the effect of the reactivation of a girdle of subduction to produce such TPW. First, we performed a reconstruction of the main continents between 615 and 520 Ma including Laurentia, Baltica, west and central Gondwana, and Australia‐Antarctica. We then implemented this paleogeography into a simple mantle dynamic model to calculate the TPW during the Ediacaran. Our results show that the reactivation of a girdle of subduction surrounding the continents along with a reduced effect of the return flow rising from the lower mantle can produce two TPW episodes consistent with the paleomagnetic observations. This mechanism is possible if the sinking velocities associated with the girdle of subduction drastically decrease between 635 and 730 Ma. Such a large geodynamic event is consistent with the detrital zircon age distribution of the Neoproterozoic supporting a low subduction activity during the Cryogenian and a boost during the Ediacaran. Decrease of subduction‐related stress induced on the lithosphere may have interrupted the rifting of the supercontinent Rodinia for 100 Ma. Finally, the weakening in subduction magmatism might have strongly reduced the CO2 flux into the atmosphere and played a major role in driving the Neoproterozoic global‐scale glaciations.

“…As noted above, the western margin of Laurentia -whether adjacent to Australia -Antarctica or South China -is of central importance to Rodinia's breakup history. Several recent stratigraphic studies and syntheses have contributed to refined correlations across the southwestern Laurentian margin through the interval of its development (Macdonald et al 2013;Mahon et al 2014;Yonkee et al 2014). Smith et al (2015) present integrated stratigraphy and detrital-zircon geochronology to demonstrate that the pre-Cryogenian Beck Springs Dolomite and adjacent units were not deposited on a broad, coherent continental margin as had been characterized by some previous workers.…”

The supercontinent-cycle hypothesis attributes planetary-scale episodic tectonic events to an intrinsic self-organizing mode of mantle convection, governed by the buoyancy of continental lithosphere that resists subduction during closure of old ocean basins, and consequent reorganization of mantle convection cells leading to opening of new ocean basins. Characteristic timescales of the cycle are typically 500-700 myr. Proposed spatial patterns of cyclicity range from hemispheric (introversion) to antipodal (extroversion), to precisely between those end-members (orthoversion). Advances in our understanding can arise from theoretical or numerical modelling, primary data acquisition relevant to continental reconstructions, and spatiotemporal correlations between plate kinematics, geodynamic events and palaeoenvironmental history. The palaeogeographic record of supercontinental tectonics on Earth is still under development. The contributions in this special publication provide snap-shots in time of these investigations and indicate that Earth's palaeogeographic record incorporates elements of all three endmember spatial patterns.
