After thirty years of plate-tectonic theory, the reasons why supercontinents disintegrate and disperse to form smaller continental plates remain enigmatic. Possible causes range from abnormally hot mantle upwellings, or plumes, to changes in plate-boundary driving forces. The breakup of the Gondwanaland super-continent, which started about 180 million years ago, provides an excellent case history against which to test models. 
Cretaceous vertical motion of australia and the australian- antarctic discordance
A three-dimensional model of mantle convection in which the known history of plate tectonics is imposed predicts the anomalous Cretaceous vertical motion of Australia and the present-day distinctiveExpand
Mantle Plumes and Superplumes; Continental Breakups, Supercontinent Cycles and Ore Deposits
The theory of mantle plumes was developed over the last 30 years. The etymology of the word “plume” is from the Latin “pluma”, which means feather. In French the word for plume is “panache”, whichExpand
The breakup of Rodinia: did it start with a mantle plume beneath South China?
Abstract Mafic to ultramafic dykes and sills in South China, dated as 828±7 Ma old, are identical in age to the 827±6 Ma Gairdner Dyke Swarm in Australia, thought to be of mantle plume origin. TheseExpand

Gondwana breakup and plate kinematics: Business as usual
[1] A tectonic model of the Weddell Sea is built by composing a simple circuit with optimized rotations describing the growth of the South Atlantic and SW Indian oceans. The model independently andExpand
Large igneous provinces linked to supercontinent assembly
Abstract Models for the disruption of supercontinents have considered mantle plumes as potential triggers for continental extension and the formation of large igneous provinces (LIPs). An alternativeExpand
Abstract Episodic growth of continental crust and supercontinents at 2.7, 1.9, and 1.2 Ga may be caused by superevents in the mantle as descending slabs pile up at the 660-km seismic discontinuityExpand
On the cause of continental breakup: A simple analysis in terms of driving mechanisms of plate tectonics and mantle plumes
Abstract Earth’s continents can come together to form supercontinents and the supercontinents can break apart into fragments of varying size scattering around the globe through a hypothetical processExpand
Section 7. Episodic Growth of the Continental Crust
In the previous section I proposed that Archean granitoids, like those of the present day, formed mainly in subduction settings. Two questions can now be posed. First, was the tectonic process thatExpand
A review of Wilson Cycle plate margins: A role for mantle plumes in continental break-up along sutures?
Abstract The Wilson Cycle theory that oceans close and reopen along the former suture is a fundamental concept in plate tectonics. It was named after J. Tuzo Wilson who recognised that dissimilarExpand


Lithospheric uplift in eastern Gondwana: Evidence for a long-lived mantle plume system?
Recent work has demonstrated that modern drainage systems on rifted continental margins may be the product of ancient lithospheric doming in areas of flood-basalt magmatism. This uplift is thought toExpand
The role of mantle plumes in the development of continental drainage patterns
The geomorphology of three continental flood-basalt provinces supports a recent model for the generation of such provinces by melting of hot mantle plumes. Characteristic drainage patterns indicatingExpand
Tectonomagmatic controls on Gondwana break‐up models: Evidence from the Proto‐Pacific Margin of Antarctica
Geochemical and isotopic data are presented that suggest the existence of a large, Middle Jurassic subduction-related magmatic province common to both the Antarctic Peninsula and southern SouthExpand
Large-scale mantle convection and the aggregation and dispersal of supercontinents
The first time-dependent numerical simulations of continental aggregation and dispersal demonstrate a dynamic feedback between the motion of continental plates and mantle convection. Plate velocityExpand
Antarctica-New Zealand rifting and Marie Byrd Land lithospheric magmatism linked to ridge subduction and mantle plume activity
Mid-Cretaceous igneous rocks of central Marie Byrd Land, Antarctica record a rapid change from subduction-related to rift-related magmatism. This correlates with the final stages of subduction of theExpand
Plume-Generated Triple Junctions: Key Indicators in Applying Plate Tectonics to Old Rocks
Continental lithosphere-especially where stationary with respect to mantle plumes-is marked by plume-generated uplifts typically crested by volcanoes that rupture in three rifts at angles of aboutExpand
Magmatism and the causes of continental break-up
Several late-collision and intraplate features are not entirely integrated in the classical plate tectonic model. The Pan-African orogeny (730-550 Ma) in Saharan Africa provides some insight into theExpand

Mid-Mesozoic closure of Permo–Triassic Tethys and its implications
Data from the northern Tethyan domain indicate that Permo–Triassic Palaeo-Tethys closed between the late Triassic and the mid-Jurassic. This closure was caused by the collision with Laurasia of aExpand
Geophysical evidence for a causative process for fragmentation in western Gondwana
The existence and subsequent fragmentation of the Gondwana supercontinent are well established in the geological literature. Debate continues, however, on the exact prefragmentation geometry and theExpand
