Scientific paper

During subduction, relatively hot lithospheric slabs are expected to deform in a superplastic flow regime below a depth of about 300 km if olivine reacts to fine-grained spinel. This process reduces the flow strength of such slabs below the phase boundary so that they become aseismic at about this depth. In colder slabs temperatures are too low for superplastic deformation, and a high flow strength and seismic activity are maintained to a depth of 600-700 km.
