Short summary
The borders between oceans and continents, called margins, can be convergent, divergent, or horizontally sliding. The formation of oceans occurs in a divergent context. However, some divergent margin structures display an accommodation of horizontal sliding during the opening of oceans. To study and understand how the horizontal sliding part occurring during divergence influences the margin structure, we performed 3D high-resolution numerical models evolving during tens of millions of years.
