  • Eshagh, Mehdi; Steinberger, Bernhard; Tenzer, Robert; Tassara, Andres (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Based on Hager and O’Connell's solution to mantle flow equations, the stresses induced by mantle convection are determined using the density and viscosity structure in addition to topographic data and a plate velocity ...
  • O'Connor, John M.; Steinberger, Bernhard; Regelous, Marcel; Koppers, Anthony A.P.; Wijbrans, Jan R.; Haase, Karsten M.; Stoffers, Peter; Jokat, Wilfried; Garbe-Schönberg, Dieter (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)
    Estimates of the relative motion between the Hawaiian and Louisville hot spots have consequences for understanding the role and character of deep Pacific‐mantle return flow. The relative motion between these primary hot ...
  • Torsvik, Trond Helge; Steinberger, Bernhard; Ashwal, Lewis D.; Doubrovine, Pavel; Trønnes, Reidar G (Journal article / Tidsskriftartikkel / SubmittedVersion, 2016)
    Kevin Burke’s original and thought-provoking contributions have been published steadily for the past 60 years, and more than a decade ago he set out to resolve how plate tectonics and mantle plumes interact by proposing a ...
  • Osei Tutu, Anthony; Steinberger, Bernhard; Sobolev, Stephan V.; Rogozhina, Irina; Popov, Anton A. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Abstract. The orientation and tectonic regime of the observed crustal/lithospheric stress field contribute to our knowledge of different deformation processes occurring within the Earth's crust and lithosphere. In this ...
  • Osei Tutu, Anthony; Sobolev, Stephan V.; Steinberger, Bernhard; Popov, A.A.; Rogozhina, Irina (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
  • Doubrovine, Pavel; Steinberger, Bernhard; Torsvik, Trond Helge (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    Absolute reconstructions of large igneous provinces (LIPs) for the past 300 Ma reveal a remarkable spatial pattern suggesting that almost all LIPs have erupted over the margins of the two large‐scale structures in the ...
  • Bredow, Eva; Steinberger, Bernhard; Gassmöller, René; Dannberg, Juliane (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    The Réunion mantle plume has shaped a large area of the Earth's surface over the past 65 million years: from the Deccan Traps in India along the hotspot track comprising the island chains of the Laccadives, Maldives, and ...
  • Rolf, Tobias; Steinberger, Bernhard; Sruthi, U.; Werner, Stephanie C. (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
  • Steinberger, Bernhard; Zhao, Dapeng; Werner, Stephanie C. (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2015)
    Seismic tomography can be combined with constraints from geoid, topography and other surface observations to gain information about mantle structure and dynamics. This approach has been taken with much success for the Earth ...
  • Steinberger, Bernhard; Seidel, Miriam-Lisanne; Torsvik, Trond Helge (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Earth’s spin axis follows the maximum moment of inertia axis of mantle convection, with some delay due to adjustment of the rotational bulge. Here we compute this axis for geodynamic models based on subduction history, ...
  • Gassmöller, René; Dannberg, Juliane; Bredow, Eva; Steinberger, Bernhard; Torsvik, Trond Helge (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    Hotspot tracks are thought to originate when mantle plumes impinge moving plates. However, many observed cases close to mid‐ocean ridges do not form a single age‐progressive line, but vary in width, are separated into ...
  • Steinberger, Bernhard; Gassmöller, René; Trumbull, Robert; Weber, Michael; Sobolev, Stephan V. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)
    Southern Africa was part of Gondwanaland until the Mesozoic, when this supercontinent broke up into fragments that evolved into today’s southern continents. In particular, around 140 Ma, rifting started between southern ...
  • Chertova, Mariya V.; Spakman, Wim; Steinberger, Bernhard (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    The impact of remotely forced mantle flow on regional subduction evolution is largely unexplored. Here we investigate this by means of 3D thermo-mechanical numerical modeling using a regional modeling domain. We start with ...
  • Rogozhina, Irina; Petrunin, Alexey G; Vaughan, Alan P M; Steinberger, Bernhard; Johnson, Jesse V; Kaban, Mikhail K; Calov, Reinhard; Rickers, Florian; Thomas, Maik; Koulakov, Ivan (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2016)
    Ice-penetrating radar and ice core drilling4 have shown that large parts of the north-central Greenland ice sheet are melting from below. It has been argued that basal ice melt is due to the anomalously high geothermal ...
  • Konrad, Kevin; Koppers, Anthony A.P.; Steinberger, Bernhard; Finlayson, Valerie A.; Konter, Jasper G.; Jackson, Matthew G. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Mantle plumes upwelling beneath moving tectonic plates generate age-progressive chains of volcanos (hotspot chains) used to reconstruct plate motion. However, these hotspots appear to move relative to each other, implying ...
  • Torsvik, Trond Helge; Doubrovine, Pavel; Steinberger, Bernhard; Gaina, Carmen; Spakman, Wim; Domeier, Mathew (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    A conspicuous 60° bend of the Hawaiian-Emperor Chain in the north-western Pacific Ocean has variously been interpreted as the result of an abrupt Pacific plate motion change in the Eocene (∼47 Ma), a rapid southward drift ...
  • Yuan, Xiaohui; Heit, Benjamin; Brune, Sascha; Steinberger, Bernhard; Geissler, Wolfram H.; Jokat, Wilfried; Weber, Michael (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    Northwestern Namibia, at the landfall of the Walvis Ridge, was affected by the Tristan da Cunha mantle plume during continental rupture between Africa and South America, as evidenced by the presence of the Etendeka continental ...
  • Mulyukova, Elvira; Steinberger, Bernhard; Dabrowski, Marcin; Sobolev, Stephan V. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)
    We study segregation of the subducted oceanic crust (OC) at the core-mantle boundary and its ability to accumulate and form large thermochemical piles (such as the seismically observed Large Low Shear Velocity Provinces ...
  • Steinberger, Bernhard (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    Large-scale topography may be due to several causes, including (1) variations in crustal thickness and density structure, (2) oceanic lithosphere age differences, (3) subcrustal density variations in the continental ...
