“…620 Ma to 550 Ma, are recognized along the eastern margin of Laurentia (e.g. Aleinikoff et al, 1995;Tollo et al, 2004;Kamo et al, 1989;Cawood et al, 2001). The latter pulse is conventionally regarded to have resulted in the separation of Laurentia and cratonic elements of west Gondwana (e.g.…”

“…The Late Neoproterozoic to Early Paleozoic cover records the transition from deep to shallow-water deposition along the Laurentian margin and is linked to two periods of crustal extension at 760 -680 Ma and ca. 565 Ma (Southworth et al 2009), with the latter resulting in the opening of the Iapetus Ocean (Aleinikoff et al 1995). The Late Neoproterozoic sequences include the Lynchburg Group of Virginia, which is broadly correlative with the Mount Rogers Formation of Virginia -North Carolina (felsic volcanic rocks within this formation are dated at ca.…”

“…570 Ma Catoctin and ca. 760 Ma Mount Rogers formations, Aleinikoff et al 1995) related to the rifting of Rodinia, although many of the youngest Cambrian zircons in Chopawamsic samples are younger than the majority of Rodinian rift rocks and only coeval with the youngest rift-related rocks, which are geographically and volumetrically limited (ca. 532 Ma Mt.…”
