Dynamics of slab rollback and induced back-arc basin formation

WebbSlab rollback can occur when one tectonic plate slides beneath another one. In geology, subduction is a process that occurs at certain regions, called destructive plate boundaries, where a tectonic plate moves under another tectonic plate. This process can lead to a … WebbAlthough ridge-push/slab-pull is the favoured mechanism for plate motion, it’s important not to underestimate the role of mantle convection. Without convection, there would be no ridges to push from because upward …
