Gondwana assembly: The view from Southern Africa and East Gondwana
TLDR
In this paper, the authors compile recent data regarding the timing and kinematics of tectonism for critical parts of southern Africa and East Gondwana, focusing on the period between ~ 650-500 Ma, and integrate these data into a regional framework.About:

A synopsis of events related to the assembly of eastern Gondwana
TL;DR: The assembly of the eastern part of Gondwana (eastern Africa, Arabian-Nubian shield (ANS), Seychelles, India, Madagascar, Sri Lanka, East Antarctica and Australia) resulted from a complex series of orogenic events spanning the interval from ∼750 to ∼530 Ma as mentioned in this paper.

Amalgamating eastern Gondwana: The evolution of the Circum-Indian Orogens
TL;DR: In this paper, the authors integrated Neoproterozoic palaeomagnetic solutions from the various blocks that made up eastern Gondwana, with the large amount of recent geological data available from the orogenic belts that formed as eastern gondwana amalgamated.
Journal ArticleDOI
Linking accretionary orogenesis with supercontinent assembly
Peter A. Cawood,Craig Buchan +1 more
TL;DR: The age relations for assembly of Gondwana and Pangea indicate that the timing of collisional orogenesis between amalgamating continental bodies was synchronous with subduction initiation and contractional orogens within accretionary orogens located along the margins of these supercontinents as mentioned in this paper.

Gondwanaland from 650–500 Ma assembly through 320 Ma merger in Pangea to 185–100 Ma breakup: supercontinental tectonics via stratigraphy and radiometric dating
TL;DR: Gondwanaland lasted from the late Neoproterozoic-Cambrian amalgamation of African and South American terranes to Antarctica through 320 Ma merging with Laurussia in Pangea to breakup from 185 to 100 Ma (Jurassic and Early Cretaceous).
Journal ArticleDOI
Proterozoic basement provinces of southern and southwestern Australia, and their correlation with Antarctica
TL;DR: The Pinjarra Orogen as mentioned in this paper truncates the western margin of the Yilgarn Craton and Albany-Fraser Orogen, and contains allochthonous 1100-1000Ma gneissic blocks transported along the craton margin during at least two stages of Neoproterozoic transcurrent movement.

ARC Assembly and Continental Collision in the Neoproterozoic East African Orogen: Implications for the Consolidation of Gondwanaland
TL;DR: The most important, rapid, and enigmatic changes in our Earth's environment and biota occurred during the Neoproterozoic Era (1000-540 million years ago; Ma).
Journal ArticleDOI
Did the breakout of laurentia turn gondwanaland inside-out?
TL;DR: 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.

Pacific margins of Laurentia and East Antarctica-Australia as a conjugate rift pair: Evidence and implications for an Eocambrian supercontinent
TL;DR: In this article, a geometrically acceptable computer-generated reconstruction for the latest Precambrian juxtaposes and aligns the Grenville front that is truncated at the Pacific margin of Laurentia and a closely comparable tectonic boundary in East Antarctica, along the Weddell Sea margin.

Southwest U.S.-East Antarctic (SWEAT) connection: A hypothesis
TL;DR: In this paper, 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.

TL;DR: An integrated continent-wide survey of the geology and geochronology of Africa, giving a balanced view of the history of the continent and the tectono-thermal events that have affected it throughout Precambrian time and into the Phanerozoic is presented in this paper.
