M. Stampfli, Earth Sciences Institute (ISTE) Geopolis, UNIL, CH-1015 Lausanne The new plate tectonic reconstruction model developed at UNIL (which in 2010 was sold by UNIL to Neftex Petroleum Consultants Ltd) is supported by a database including a wide range of constraints. With the permission of Neftex, this paper presents the model as it was before the transfer of ownership to Neftex. The global plate tectonic model starting at 600 Ma contains more than one thousand “geodynamic units” (GDU) defined on their present day geological history, and assembled as building stones to form terranes. Using the synthetic isochrones methodology (Stampfli and Borel 2002), plates were reconstructed by adding/removing material, along plate limits. Plate velocities were closely monitored as they represent major constraints in the kinematics of the involved terranes and continents, in conjunction with paleomagnetic data. This was an iterative process where geological data were always
