Differentiating induced versus spontaneous subduction initiation using thermomechanical models and metamorphic soles
Abstract
The mechanism of subduction initiation is a key to modern plate tectonics. Here, using numerical modeling and geological observations, the authors find that the majority of active and paleo subduction zones with metamorphic soles likely formed during induced subduction initiation that involved a young overriding plate.
