Workshop Announcement: Marginal Plateaus

This workshop, taking place in November 2017, will investigate marginal plateaus, from magmatic divergent margins to transform margins, and from the continental shelf to the pelagic and contouritic setting.

The aims of this workshop are to compare the numerous marginal plateaus in the world, and to bring together specialists from different Earth science fields, in order to investigate:

  • The nature of the basement (thinned continental crust, magmatic crust) and how it was deformed or emplaced,
  • The relationships between marginal plateaus, hot spots and magmatic divergent margins,
  • The structure of transform margins that are associated with marginal plateaus,
  • The control of inherited structures on the polyphased evolution of those domains,
  • The evolution of subsidence (and uplift), from the initial magmatic rifting to the secondary rift stage and transform opening, and, finally, to the post-rift sag stage,
  • The influence of the topography of marginal plateaus on the local and global circulation of intermediate and deep oceanic waters,
  • The specific sedimentary systems that develop in those deep-current dominated settings.

Keynote speakers:

  • Lies Loncke – University Perpignan, France: Marginal plateaus: definition and scientific challenges
  • Walter Roest – IFREMER, Brest, France: An overview of the scientific exploration of the Demerara plateau
  • Asbjorn Breivik – University of Oslo, Norway: Why is the Vøring Plateau a plateau?
  • Gavin Elliott – Lukoil, United Kingdom: An overview of the Hatton-Rockall plateau
  • Dave McCarthy – British Geological Survey, Edinbourgh, United Kingdom: The Falkland plateau
  • Arne Døssing – Technical University of Denmark: The Alpha ridge
  • Scott Bryan – Queensland University, Brisbane, Australia: Large ignous provinces, continental break-up and marginal plateaus
  • Christophe Basile – University Grenoble-Alpes, France: Transform margins along marginal plateaus
  • Javier Hernandez-Molina – Royal Holloway University, London, United Kingdom: Contourite terraces vs marginal platforms: conceptual implications

Contributions:

  • We welcome contributions on all topics related to marginal plateaus, either based on case studies, on synthetic studies or on modelisation.
