Abstract Mechanisms that can explain the Mesozoic motion of Pangaea in a palaeomagnetic mantle reference frame may also be able to explain its breakup. Calculations indicate that Pangaea moved along a non-rigid path in the mantle frame between the late Triassic and early Jurassic. The breakup of Pangaea may have happened as a response to this non-rigid motion. Tectonic forces applied to the margins of Pangaea as a consequence of subduction at its peripheries can explain both the motion and… Expand
Paleozoic plate kinematics during the Pannotia–Pangaea supercontinent cycle
Abstract Three supercontinents have been suggested to have existed in the last 1 Gyr. The supercontinent status of Pangaea and Rodinia is undisputed. In contrast, there is ongoing controversy onExpand
Linking collisional and accretionary orogens during Rodinia assembly and breakup: Implications for models of supercontinent cycles
Periodic assembly and dispersal of continental fragments has been a characteristic of the solid Earth for much of its history. Geodynamic drivers of this cyclic activity are inferred to be eitherExpand
Switching from advancing to retreating subduction in the Neoproterozoic Tarim Craton, NW China: Implications for Rodinia breakup
Abstract Geodynamic drivers for the supercontinent cycle are generally attributed to either top-down (subduction-related) or bottom-up (mantle-related) processes. Compiled geochemical data and U–PbExpand
LIPs, orogens and supercontinents: The ongoing saga
Abstract Of nine large age peaks in zircon and LIP time series New paleogeographic reconstructions of supercontinents indicate that in the last 2 Gyr average angular plate speeds have not changed orExpand
A review of Pangaea dispersal and Large Igneous Provinces – In search of a causative mechanism
Abstract The breakup of Pangaea was accompanied by extensive, episodic, magmatic activity. Several Large Igneous Provinces (LIPs) formed, such as the Central Atlantic Magmatic Province (CAMP) and theExpand
Four-dimensional context of Earth's supercontinents
Abstract The supercontinent-cycle hypothesis attributes planetary-scale episodic tectonic events to an intrinsic self-organizing mode of mantle convection, governed by the buoyancy of continentalExpand
Revisiting the Mesoproterozoic
Abstract Many of the peculiar features of the Mesoproterozoic (1.6–1.0 Ga) are related to the assembly of the first supercontinent Nuna, and some may not be distinctive of this time period. A highExpand
Early Triassic development of a foreland basin in the Canadian high Arctic: Implications for a Pangean Rim of Fire
Abstract Following the amalgamation of Laurasia and Gondwana to form Pangea, some Triassic tectonic models show an encircling arc system called the “Pangean Rim of Fire”. Here we show that theExpand
Is there a Grenvillian orogen in the southwestern Tarim Craton?
Abstract The Rodinia Supercontinent assembled through global-scale Grenvillian (1300–900 Ma) orogeny, so identification and correlation of Grenvillian orogens is fundamental to the geologicalExpand
Comment on "Neotethyan subduction ignited the Iran arc and back-arc differently" by Shafaii Moghadam et al. (2020)
Shafaii Moghadam et al. (2020) contribute important new data on Late Cretaceous-Tertiary subduction- related magmatism in Iran, but their plate convergence model, wherein Neotethyan subduction beginsExpand


Role of tonalite-trodhjemite-granite (TTG) crust subduction on the mechanism of supercontinent breakup
Abstract The tonalite-trondhjemite-granite (TTG) crust has been considered to be buoyant and hence impossible to be subducted into the deep mantle. However, recent studies on the juvenile arc in theExpand
Supercontinents, mantle dynamics and plate tectonics: A perspective based on conceptual vs. numerical models
Abstract The periodic assembly and dispersal of supercontinents through the history of the Earth had considerable impact on mantle dynamics and surface processes. Here we synthesize some of theExpand
Two-stage rifting of Pangea by two different mechanisms
Two types of rifting may have characterized the two-stage breakup of Pangea—passive rifting during Early Jurassic rapid supercontinental motion and active rifting during Cretaceous supercontinentalExpand
The intraplate character of supercontinent tectonics
Abstract For several decades geoscientists have recognised intraplate tectonic activity far from plate margins, both from modern and ancient examples. This apparent disconnect with the drivers ofExpand
The making and breaking of supercontinents: Some speculations based on superplumes, super downwelling and the role of tectosphere
Abstract The mechanisms of formation and disruption of supercontinents have been topics of debate. Based on the Y-shaped topology, we identify two major types of subduction zones on the globe: theExpand
Breakup of a supercontinent between 625 Ma and 555 Ma: new evidence and implications for continental histories
Abstract A method developed recently for constructing tectonic subsidence curves in early Paleozoic miogeoclines has produced new evidence for the breakup of a late Proterozoic supercontinent.Expand
Plumes, orogenesis, and supercontinental fragmentation
Abstract A time–space relationship between large igneous provinces (LIPS), present day hot spots, and the fragmentation of Pangea has been documented over several decades, but the cause ofExpand
How the closure of paleo-Tethys and Tethys oceans controlled the early breakup of Pangaea
Two end-member models have been invoked to accommodate the Mesozoic dispersal of the supercontinent Pangaea. In one end-member, the opening of the Atlantic Ocean is inferred to have been balanced byExpand
Supercontinent model for the contrasting character of Late Proterozoic orogenic belts
Two fundamentally different types of orogenic belts may reflect the accretion and breakup of a Late Proterozoic supercontinent. Interior orogens (e.g., trans- Saharan fold belts) lie within theExpand
The opening of Sirte basin: Result of slab avalanching?
Abstract North Africa's Sirte basin opening is an enigmatic feature in the complex Meso-Cenozoic rearrangement of Mediterranean tectonics. New borehole data inversion constrains its deformationExpand
