Global continental and ocean basin reconstructions since 200 Ma
Global plate motion models provide a spatial and temporal framework for geological data and have been effective tools for exploring processes occurring at the earth's surface. However, publishedExpand
Role of temperature‐dependent viscosity and surface plates in spherical shell models of mantle convection
Layered viscosity, temperature-dependent viscosity, and surface plates have an important effect on the scale and morphology of structure in spherical models of mantle convection. We find thatExpand
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
Next-generation plate-tectonic reconstructions using GPlates
Plate tectonics is the kinematic theory that describes the large-scale motions and events of the outermost shell of the solid Earth in terms of the relative motions and interactions of large, rigid,Expand
Evolving force balance during incipient subduction
Nearly half of all active subduction zones initiated during the Cenozoic. All subduction zones associated with active back arc extension have initiated since the Eocene, hinting that back arcExpand
A benchmark study on mantle convection in a 3-D spherical shell using CitcomS
As high-performance computing facilities and sophisticated modeling software become available, modeling mantle convection in a three-dimensional (3-D) spherical shell geometry with realistic physicalExpand
Constraining mantle density structure using geological evidence of surface uplift rates: The case of the African Superplume
We explore the hypothesis that southern Africa is actively being uplifted by a large-scale, positively buoyant structure within the mid-lower mantle. Using a new formulation in which dynamicExpand
The role of oceanic plateau subduction in the Laramide orogeny
The cause of the Laramide phase of mountain building remains uncertain. Conceptual models implicate the subduction of either ocean ridges or conjugates of the buoyant Hess or Shatsky oceanicExpand
Sharp Sides to the African Superplume
Using a fortuitous set of SKS phases that travel along its eastern side, it is shown that the boundary of the anomaly appears to be sharp, with a width less than 50 kilometers, and is tilted outward from its center. Expand
Phanerozoic marine inundation of continents driven by dynamic topography above subducting slabs
A spherical model of mantle flow constrained by the locations of trenches can be used to predict the dynamic topography of the Earth's surface, and hence the marine inundation of continents. For pastExpand
