    Description

    A major debate in plate tectonics concerns the driving mechanism for formation of extensional back-arc basins in the overriding plate along a convergent tectonic boundary, where a subducting plate is thrust into the mantle underneath an overriding plate. One hypothesis states that such extension results from sinking and rollback of the subducting plate. The physical validity of this hypothesis will be tested using both laboratory and numerical modelling techniques. The modelling will investigate overriding plate - subducting plate - mantle interaction in three-dimensional space and quantify the role of key physical parameters on the subduction process.
