  • Magni, Valentina; Allen, Mark B.; van Hunen, Jeroen; Bouilhol, Pierre (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)
    We present three-dimensional numerical models to investigate the dynamics of continental collision, and in particular what happens to the subducted continental lithosphere after oceanic slab break-off. We find that in some ...
  • Karlsen, Krister Stræte; Conrad, Clinton Phillips; Magni, Valentina (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    First‐order variations in sea level exhibit amplitudes of ∼200 m over periods that coincide with those of supercontinental cycles (∼300–500 Myr). Proposed mechanisms for this sea level change include processes that change ...
  • Magni, Valentina (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    Mantle flow is a key feature that can affect melt production and composition in and around subduction zones. In this study, I use three-dimensional numerical models to investigate the role of mantle flow on subduction-related ...
  • Domeier, Mathew; Magni, Valentina; Hounslow, Mark W.; Torsvik, Trond Helge (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    Decades of geochronological work have shown the temporal distribution of zircon ages to be episodic on billion-year timescales and seemingly coincident with the lifecycle of supercontinents, but the physical processes ...
  • van den Broek, Joost Martijn; Magni, Valentina; Gaina, Carmen; Buiter, Susanne (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Microcontinents and continental fragments are pieces of continental lithosphere, formed by extension and breakup, followed by plate boundary relocations. Microcontinents or continental fragments affiliated with passive ...
  • Riel, Nicolas; Bouilhol, Pierre; van Hunen, Jeroen; Cornet, Julien; Magni, Valentina; Grigorova, Vili; Velic, Mirko (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    The magmatic processes occurring in the lowermost arc crust play a major role in the evolution of mantle-wedge-derived melt. Geological evidence indicates that mantle-derived magmas and in-situ products of lower crust ...
  • Magni, Valentina (Journal article / Tidsskriftartikkel / SubmittedVersion, 2017)
    The processes that form and recycle continental crust have changed through time. Numerical models reveal an evolution from extensive recycling on early Earth as the lower crust peeled away, to limited recycling via slab ...
  • Schliffke, Nicholas; van Hunen, Jeroen; Magni, Valentina; Allen, Mark B. (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)
    During continental collision, considerable amounts of buoyant continental crust subduct to depth and subsequently exhume. Whether various exhumation paths contribute to contrasting styles of magmatism across modern collision ...
