  • Steinberger, Bernard; Torsvik, Trond Helge; Dubrovin, Pavel (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)
    We defined a new global moving hot spot reference frame (GMHRF), using a comprehensive set of radiometric dates from arguably the best‐studied hot spot tracks, refined plate circuit reconstructions, a new plate polygon ...
  • Van Hinsbergen, Douwe; Steinberger, Bernard; Gassmöller, René; Dubrovin, Pavel (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2011)
    A strong 50–35 Ma decrease in India‐Asia convergence is generally ascribed to continent‐continent collision. However, a convergence rate increase of similar magnitude occurred between ∼65–50 Ma. An earlier increase occurred ...
  • Buiter, Susanne; Steinberger, Bernard; Medvedev, Sergei; Tetreault, Joya L. (Journal article / Tidsskriftartikkel / SubmittedVersion; Peer reviewed, 2012)
    The Congo Basin is characterised by a near-circular shape, a pronounced negative free-air gravity anomaly, and a subsidence history that is slow and long-lived. The basin is often considered as an intracratonic basin, ...
  • Steinberger, Bernard; Werner, Stephanie; Torsvik, Trond Helge (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2010)
    The relation between gravity anomalies, topography and volcanism can yield important insights about the internal dynamics of planets. From the power spectra of gravity and topography on Earth, Venus and Mars we infer that ...
  • Torsvik, Trond Helge; Burke, K; Steinberger, Bernard; Webb, Susan J; Ashwal, Lewis D. (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2010)
    Diamonds are formed under high pressure more than 150 kilometres deep in the Earth’s mantle and are brought to the surface mainly by volcanic rocks called kimberlites. Several thousand kimberlites have been mapped on various ...
  • Steinberger, Bernard; Torsvik, Trond Helge (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)
    We present geodynamic models featuring mantle plumes that are almost exclusively created at the margins of large thermo‐chemical piles in the lowermost mantle. The models are based on subduction locations and fluxes inferred ...
  • Lee, Choon-Ki; Han, Shin-Chan; Steinberger, Bernard (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2011)
    The radial viscosity structure of the Earth is explored on the basis of the geoid observations. The variations of uncertainty in seismic tomography models are accounted for when finding the radial viscosity structure. The ...
  • Faccenna, Claudio; Becker, Thorsten W.; Lallemand, Serge; Steinberger, Bernard (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)
    We analyze the role of slab pull acting on the Pacific plate during its early Tertiary change in motion. Slab pull forces are estimated by integrating the negative buoyancy of a 700 km long slab along a revised subduction ...
  • Torsvik, Trond Helge; Van der Voo, Rob; Preeden, Ulla; Mac Niocaill, Conall; Steinberger, Bernard; Van Hinsbergen, Douwe; Domeier, Mathew; Gaina, Carmen; Tohver, Eric; Meert, Joseph G.; McCausland, Phil J. A.; Cocks, Robin L. M.; Dubrovin, Pavel (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2012)
    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 ...
  • Torsvik, Trond Helge; Steinberger, Bernard; Gurnis, M; Gaina, Carmen (Journal article / Tidsskriftartikkel / SubmittedVersion, 2010)
    We have developed an improved model of global digital palaeo-plate boundaries and plate motion to describe the distribution and history of plates since the Late Jurassic. From this history we computed net lithospheric ...
  • Biggin, Andrew J.; Steinberger, Bernard; Aubert, Julien; Suttie, Neil; Holme, Richard; Torsvik, Trond Helge; van der Meer, Douwe G.; Van Hinsbergen, Douwe (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2012)
    The Earth's internal magnetic field varies on timescales of months to billions of years. The field is generated by convection in the liquid outer core, which in turn is influenced by the heat flowing from the core into the ...
  • Torsvik, Trond Helge; Amundsen, Hans; Hartz, Ebbe Hvidegård; Corfu, Fernando; Kusznir, Nick; Gaina, Carmen; Dubrovin, Pavel; Steinberger, Bernard; Ashwal, Lewis D.; Jamtveit, Bjørn (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2013)
    The Laccadive–Chagos Ridge and Southern Mascarene Plateau in the north-central and western Indian Ocean, respectively, are thought to be volcanic chains formed above the Réunion mantle plume1 over the past 65.5 million ...
  • Conrad, Clinton P.; Steinberger, Bernard; Torsvik, Trond Helge (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2013)
    Viscous convection within the mantle is linked to tectonic plate motions and deforms Earth’s surface across wide areas. Such close links between surface geology and deep mantle dynamics presumably operated throughout Earth’s ...
  • Steinberger, Bernard; Torsvik, Trond Helge; Becker, Thorsten W. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)
    It is generally believed that subduction of lithospheric slabs is a major contribution to thermal heterogeneity in Earth's entire mantle and provides a main driving force for mantle flow. Mantle structure can, on the one ...
  • Steinberger, Bernard; Torsvik, Trond Helge (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2010)
    Earth's orientation relative to its spin axis is determined by its nonhydrostatic inertia tensor. We show here that the present‐day nonhydrostatic inertia tensor can be modeled by combining contributions due to large low ...
  • Burke, Kevin; Werner, Stephanie; Steinberger, Bernard; Torsvik, Trond Helge (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2012)
    The equipotential figures of Earth (residual geoid), and of Mars (areoid) are characterized by pairs of elevated and pairs of depressed antipodal equatorial regions. Elevated regions of the residual geoid lie vertically ...
