Comparative geology suggests that the continents adjacent to northern, western, southern, and eastern Laurentia in the Late Proterozoic were Siberia, Australia-Antarctica, southern Africa, and Amazonia-Baltica, respectively. Late Proterozoic fragmentation of the supercontinent centered on Laurentia would then have been followed by rapid fan-like collapse of the (present) southern continents and eventual consolidation of East and West Gondwanaland. In this scenario, a pole of rotation near the… 

Transforming Siberia along the Laurussian margin

Paleozoic rotation of the Siberian craton along transform faults on the western Laurussian margin is a hypothesis that incorporates geologic and paleomagnetic evidence. The hypothesis could

Tectonic assembly of Gondwana

Are Neoproterozoic glacial deposits preserved on the margins of Laurentia related to the fragmentation of two supercontinents

Remarkably similar deposits representing two Neoproterozoic glaciations are present on the west and east sides of Laurentia. Although now located near the margins of Laurentia, these glaciogenic

The evolution of the late Paleoproterozoic Wernecke Supergroup, Wernecke Mountains, Yukon, from sedimentation to deformation

The Wernecke Supergroup of Yukon is a metasedimentary succession deposited between ca. 1.66 and 1.60 Ga on the northwestern margin of ancestral North America (Laurentia). U-Pb detrital zircon

The South Atlantic Meso-Cenozoic continental margins are located in regions characterized by a long-lived history of Proterozoic extension, structural inversion and compressional remobilization of

Positions of the East Asian cratons in the Neoproterozoic supercontinent Rodinia

Three major East Asian crustal blocks, the Tarim, North China and South China Blocks, have records of the Neoproterozoic rifting events that broke up the supercontinent Rodinia. A preliminary
