Geophysics - Subduction and slab detachment in the Mediterranean-Carpathian region

Seismic tomography models of the three-dimensional upper mantle velocity st ructure of the Mediterranean-Carpathian region provide a better understandi ng of the lithospheric processes governing its geodynamical evolution. Slab detachment, in particular lateral migration of this process along the plat e boundary, is a key element in the lithospheric dynamics of the region dur ing the last 20 to 30 million years. It strongly affects arc and trench mig ration, and causes along-strike variations in vertical motions, stress fiel ds, and magmatism. In a terminal-stage subduction zone, involving collision and suturing, slab detachment is the natural last stage in the gravitation al settling of subducted lithosphere.
