<Taras V. Gerya> coauthored three-dimensional <geodynamic modelling> of plume-triggered <subduction initiation>. The models combine a negatively buoyant plate, localized magmatic weakening and a sufficiently weak hydrated interface to test the onset of self-sustaining descent.<Plate tectonics on the Earth triggered by plume-induced subduction initiation by Taras V. Gerya and others>[Abstract: three physical conditions for sustained subduction]{ref}
The mechanism addresses how a strong outer shell can begin to fail and sink. Showing that this occurs under specified conditions establishes a possible route to plate motion, rather than dating the first terrestrial episode.
