GeoArctic has significantly advanced deformable plate modelling with the development of the first palinspastic deformable-margin plate reconstruction software that accurately removes the effects of pre-breakup extension across conjugate margins to better evaluate basin formation and evolution.
The PlateDEF study for the North Atlantic covers the conjugate margins of Newfoundland-Ireland and East Greenland-Europe and sheds light on the deep water hyperextended basins around the margins
The PlateDEF study for Baffin-Labrador-West Greenland provides new insights into the complex interaction between rifting, strike-slip fault zones, and Cenozoic compression.
The PlateDEF plate study for the Circum-Arctic is based on years of work in the area, reinterpretation of all relevant public domain data, and new gravity and structural modeling.
The PlateDEF plate study for the Central Atlantic covers the conjugate margins of Newfoundland-Iberia, Nova Scotia-Morocco, and the US Eastern Seaboard-Northwest and West Africa.
PlateDEF models quantify and accommodate the amount and direction of crustal stretching and shortening for key tectonic events at convergent, extensional and transform margins using a proprietary palinspastic deformable-margin plate reconstruction software and method.
Exploration on deep-water continental margins brings increased awareness of the importance of plate kinematic modelling and deformable plate tectonic reconstructions as exploration tools. Rigid plate kinematic models do not adequately model the complex multiphase breakup history of the North and Central Atlantic and Arctic Oceans.
As continental crust is extended on rifted margins prior to breakup, there is plate overlap along these margins when plates are reconstructed using rigid plate kinematic models alone.
Shortening of the crust takes place on convergent margins resulting in underfit when the plates are reconstructed.
The accurate reconstruction and restoration of plate margins requires a new approach to plate kinematics and a new generation of plate reconstruction software.Read More
