Dynamics of Post-Slab Breakoff in Convergent Plate Margins: A “Jellyfish” Model
Bhaskar KunduM. Santosh
The Earth9s subduction zones are characterized by a complex architecture of the subducting slabs, including necking, tearing, detachment from the surface plate, breakoff or ultimate slab loss, in contrast to...
