Late Neoproterozoic and Early Cambrian palaeogeography: models and problems

  title={Late Neoproterozoic and Early Cambrian palaeogeography: models and problems},
  author={Sergei A. Pisarevsky and J. Brendan Murphy and Peter A. Cawood and Alan S. Collins},
Abstract We present two alternative sets of global palaeogeographical reconstructions for the time interval 615–530 Ma using competing high and low-latitude palaeomagnetic data subsets for Laurentia in conjunction with geological data. Both models demonstrate a genetic relationship between the collisional events associated with the assembly of Gondwana and the extensional events related to the opening of the Tornquist Sea, the eastern Iapetus Ocean (600–550 Ma), and the western Iapetus Ocean… Expand

Neoproterozoic glaciations in a revised global palaeogeography from the breakup of Rodinia to the assembly of Gondwanaland
Abstract This review paper presents a set of revised global palaeogeographic maps for the 825–540 Ma interval using the latest palaeomagnetic data, along with lithological information forExpand
Contemporaneous assembly of Western Gondwana and final Rodinia break-up: Implications for the supercontinent cycle
Abstract Geological, geochronological and isotopic data are integrated in order to present a revised model for the Neoproterozoic evolution of Western Gondwana. Although the classical geodynamicExpand
Chapter 8 Tectonic Events and Palaeogeographic Evolution of Southwestern Gondwana in the Neoproterozoic and Cambrian
Abstract A new geodynamic model is presented for southwestern Gondwana amalgamation. Rifting of Rodinia was a protracted process, advancing from the boundaries of the supercontinent toward its core,Expand
A diachronous opening of the Iapetus Ocean in the Neoproterozoic
<p><span>The late Neoproterozoic is a time interval of dramatic changes affecting the biosphere, the cryosphere and the lithosphere, including the final disaggregation of the supercontinent RodiniaExpand
Cambrian transgression and radiation linked to an Iapetus-Pacific oceanic connection?
The geologically abrupt appearance in the fossil record of almost all animal phyla is referred to as the Cambrian radiation or “explosion” of life on Earth. Also known as “Darwin’s dilemma,” becauseExpand
Neoproterozoic low latitude glaciations : an African perspective
The Neoproterozoic is one of the most enigmatic periods in Earth history. In the juxtaposition of glacial and tropical deposits the sedimentary record provides evidence for extreme climate change.Expand

Abstract The Neoproterozoic Eon is relatively poorly known from a petroleum perspective, despite the existence of producing, proven and potential plays in many parts of the world. In tectonic,Expand
Chapter 1 The Neoproterozoic and Cambrian: A Time of Upheavals, Extremes and Innovations☆
Abstract The Neoproterozoic stands out as a period of innovations and upheavals. The extreme palaeoclimatic, palaeoceanographic and biotic events that characterize the Neoproterozoic Era areExpand
Late Ediacaran paleogeography of Avalonia and the Cambrian assembly of West Gondwana
Abstract The latest Proterozoic tectonic evolution of Avalonia, one of the largest peri-Gondwanan terranes, bears on the issue of Gondwana amalgamation during the transition from Rodinia to Pangea.Expand
Neoproterozoic sedimentary rocks track the location of the Lhasa Block during the Rodinia breakup
Abstract Cimmerian terranes in Tibet are thought to be as old as Archean or as young as Neoproterozoic or even early Paleozoic in age. However, their Precambrian history and their role in theExpand


The Neoproterozoic Supercontinent: Rodinia or Palaeopangaea?
Abstract The Rodinia reconstruction of the Neoproterozoic Supercontinent has dominated discussion of the late Precambrian Earth for the past decade and originated from correlation of sedimentaryExpand
Neoproterozoic (∼600 Ma) aggregation of Western Gondwana: a tentative scenario
Abstract Gondwana resulted from accretion of fragments of the Rodinia supercontinent. However, precise times and circumstances of individual accretions are still disputed. Aggregation of WesternExpand

OVERVIEW: Neoproterozoic-Paleozoic geography and tectonics: Review, hypothesis, environmental speculation
The ever-changing distribution of continents and ocean basins on Earth is fundamental to the environment of the planet. Recent ideas regarding pre-Pangea geography and tectonics offer freshExpand
Endings and beginnings: Paleogeography of the Neoproterozoic–Cambrian transition

Origin of the Rheic Ocean: rifting along a Neoproterozoic suture?
The Rheic Ocean is widely believed to have formed in the Late Cambrian–Early Ordovician as a result of the drift of peri-Gondwanan terranes, such as Avalonia and Carolina, from the northern margin ofExpand
Linking accretionary orogenesis with supercontinent assembly
Abstract Age relations for assembly of Gondwana and Pangea indicate that the timing of collisional orogenesis between amalgamating continental bodies was synchronous with subduction initiation andExpand
