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… Expand

Topics from this paper

The tectonic context of the Early Palaeozoic southern margin of Gondwana
Abstract The oceanic southern margin of Gondwana, from southern South America through South Africa, West Antarctica, New Zealand (in its pre-break-up position), and Victoria Land to EasternExpand
Paleozoic Laurentia-Gondwana interaction and the origin of the Appalachian-Andean mountain system
Laurentia, the rift-bounded Precambrian nucleus of North America, may have broken out from a Neoproterozoic supercontinent between East and West Gondwana. Several lines of evidence suggest that theExpand
Proterozoic–Early Paleozoic evolution in western South America—a discussion
Abstract The hypothesis of exotic terranes in Peru, Bolivia, Argentina and Chile generated discussions on the mode of transfer and extent of accretional events that may have occurred in the southernExpand
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 couldExpand
Tectonic assembly of Gondwana
Abstract The Paleozoic assembly of Pangea, with Gondwana as its southern half, completed the last full cycle of growth and dispersal of supercontinents during earth history. This assembly apparentlyExpand
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 glaciogenicExpand
The position of the Amazonian Craton in supercontinents
Abstract This paper examines the extensive regions of Proterozoic accretionary belts that either formed most of the Amazonian Craton, or are marginal to its southeastern border. Their overallExpand
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 zirconExpand
From Collision to Extension: the Roots of the Southeastern Continental Margin of Brazil
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 ofExpand
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 preliminaryExpand


Pan-African microplate accretion of the Arabian Shield
The late Proterozoic Arabian Shield is composed of at least five geologically distinct terranes (microplates) separated by four ophiolite-bearing suture zones. Three ensimatic island-arc terranesExpand
Cambrian-Ordovician paleogeography of Baltica
Recent paleomagnetic data and existing paleontological evidence show that Baltica occupied temperate southern latitudes during Cambrian and Early Ordovician time, but was inverted with reference toExpand
Precambrian tectonic evolution of part of Gondwana, southwestern Australia
Southwestern Australia has a long dynamic Precambrian history of crustal fragmentation and aggregation by continental collision and accretion. This interpretation contrasts with the widely heldExpand
Pacific margins of Laurentia and East Antarctica-Australia as a conjugate rift pair: Evidence and implications for an Eocambrian supercontinent
Evidence supports the hypothesis that the Laurentian and East Antarctic-Australian cratons were continuous in the late Precambrian and that their Pacific margins formed as a conjugate rift pair. BothExpand
Model for the evolution of the Avalonian-Cadomian belt
The inception and termination of the ca. 670-550 Ma Avalonian-Cadomian orogenic cycle are interpreted in terms of the amalgamation and breakup of a late Precambrian supercontinent. Synorogenic,Expand
Southwest U.S.-East Antarctic (SWEAT) connection: A hypothesis
A hypothesis for a late Precambrian fit of western North America with the Australia-Antarctic shield region permits the extension of many features through Antarctica and into other parts of Gondwana.Expand
Isotope and geochemical constraints on Proterozoic crustal evolution in south-eastern Africa
Proterozoic exposures south of the imbricate thrust terrane in the eastern sector of the Namaqua-Natal Belt of southern Africa are dominated by granitoid plutons intrusive into older supracrustalExpand
Abstract The main stages of the geotectonic evolution during the Precambrian of the Siberian platform are older than those in the other blocks of eastern Asia. Upper Proterozoic orogenic stages tookExpand
Definition of the lapetus rift-drift transition in western Newfoundland
The change from a sequence of terrestrial and marine clastic sedimentary and volcanic rocks that show rapid lateral variability of thickness and facies to an overlying, essentially sheetlike, mainlyExpand
Proterozoic supercontinent, its latest Precambrian rifting, breakup, dispersal into smaller continents, and subsidence of their margins: Evidence from Asia
Several large cratons and numerous smaller blocks, all with Precambrian sialic crust, are seen clearly in the present-day structure of Asia. The outer parts of larger Precambrian terranes and entireExpand
