Numerical modelling of the Wilson Cycle
Joya Tetreault, Reza Khabbaz Ghazian
The continuous movement of the tectonic plates, of which Earth’s outer shell is composed, causes regions of plate convergence and divergence. In this project, we investigate the dynamics of plate convergence, the end of convergence by continental collision, and the localisation of subsequent extension. Using dynamic forward models, we examine how the style of convergent margin dynamics is affected by internal (e.g. rheology) and external (e.g. plate velocities) factors, how terranes may be accreted, and how a convergent margin system changes once an ocean is closed and two continents collide.
