Supercontinent cycles, true polar wander, and very long-wavelength mantle convection
TLDR
In this article, the authors show that mobile-lid mantle convection in a three-dimensional spherical shell with observationally constrained mantle viscosity structure, and realistic convective vigor and internal heating rate is characterized by either a spherical harmonic degree-1 planform with a major upwelling in one hemisphere and a major downwelling on the other hemisphere when continents are absent, or a degree-2 plan form with two antipodal major upswellings when a supercontinent is present, causing the cyclic processes of assembly and breakup of supercontinentsAbout:

TL;DR: A significant number of new palaeomagnetic poles have become available since the last time a compilation was made (assembled in 2005, published in 2008) to indicate to us that a new and significantly expanded set of tables with palaeOMagnetic results would be valuable, with results coming from the Gondwana cratonic elements, Laurentia, Baltica/Europe, and Siberia as mentioned in this paper.

The supercontinent cycle: A retrospective essay
TL;DR: In this article, the authors trace the development of ideas concerning long-term episodic orogeny and continental crust formation, such as those embodied in the chelogenic cycle, through the first realization that such episodicity was the manifestation of the cyclic assembly and breakup of supercontinents, to the surge in interest in supercontinent reconstructions.

Diamonds sampled by plumes from the core–mantle boundary

TL;DR: Torsvik et al. as mentioned in this paper used a plate-tectonic reconstruction for the past 540 million years to locate the positions of these cratons relative to the deep mantle at times when kimberlites were erupted.

Mesozoic─Cenozoic geological evolution of the Himalayan-Tibetan orogen and working tectonic hypotheses
Paul Kapp,Peter G. DeCelles +1 more
TL;DR: In this article, the authors synthesize the Triassic through Cenozoic geology of the central Himalayan-Tibetan orogen and presents their tectonic interpretations in a time series of schematic lithosphere-scale cross-sections and paleogeographic maps.

TL;DR: Sedimentary, igneous and metamorphic proxies along with palaeomagnetic data are reviewed to infer both the development of rigid lithospheric plates and their independent relative motion, and conclude that significant changes in Earth behaviour occurred in the mid- to late Archaean.

TL;DR: A brief synthesis of the current state of knowledge on the formation and break-up of the early Neoproterozoic supercontinent Rodinia and the subsequent assembly of Gondwanaland is presented in this paper.

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.
Journal ArticleDOI
Evidence for deep mantle circulation from global tomography
TL;DR: In this paper, P-wave travel times and improved earthquake locations were used for mantle-wide convective flow, and the use of body waves made it possible to resolve long, narrow structures in the lower mantle some of which can be followed to sites of present day plate convergence at the Earth's surface.

Geochronology of Neoproterozoic syn-rift magmatism in the Yangtze Craton, South China and correlations with other continents: evidence for a mantle superplume that broke up Rodinia
TL;DR: In this article, the authors showed that there were two major phases of widespread bimodal magmatism in South China during the Neoproterozoic, one starting before the continental rift but continued into the first two stages of the rifting.

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.
