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 fresh opportunities to examine possible causative relations between tectonics and environmental and biologic changes during the Neoproterozoic and Paleozoic eras. The starting point is an appreciation that Laurentia, the rift-bounded Precambrian core of North America, could have been juxtaposed with the cratonic… 

Animated History of Avalonia in Neoproterozoic-Early Palaeozoic

Current debate regarding the configuration and breakup history of the late Precambrian supercontinent Rodinia has focused on the development of Grenville-aged orogenic belts and the evolution of

Neoproterozoic Extension on the Scottish Promontory of Laurentia: Paleogeographic and Tectonic Implications

The Hebridean shield, the northwest foreland of the Caledonian Orogen of Scotland, is a small fragment of Laurentia detached during the Cenozoic opening of the North Atlantic Ocean and is now part of

Early Cambrian palaeogeography and the probable Iberia–Siberia connection

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,” because

Neoproterozoic-early Palaeozoic tectonostratigraphy and palaeogeography of the peri-Gondwanan terranes: Amazonian v. West African connections

Abstract Within the Appalachian–Variscan orogen of North America and southern Europe lie a collection of terranes that were distributed along the northern margin of West Gondwana in the late

Global Tectonic Setting and Climate of the Late Neoproterozoic: A Climate‐Geochemical Coupled Study

Whereas the snowball Earth hypothesis seems to account for most of the major features of the Neoproterozoic glacial records, the causes that drove the Earth into a snowball state remain largely open

The Laurentian record of Neoproterozoic glaciation, tectonism, and eukaryotic evolution in Death Valley, California

Neoproterozoic strata in Death Valley, California, contain eukaryotic microfossils and glacial deposits that have been used to assess the severity of putative snowball Earth events and the biological

Paleomagnetic constraints on timing of the Neoproterozoic breakup of Rodinia and the Cambrian formation of Gondwana

Paleomagnetic data from East Gondwana (Australia, Antarctica, and India) and Laurentia are interpreted to demonstrate that the two continents were juxtaposed in the Rodinia supercontinent by 1050 Ma.

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 the

In terms of plate tectonic theory, and by analogy with modern continental margins, the Appalachian orogen evolved through a sequence of interrelated sedimentation-deformation-metamorphism patterns
