“…Moreover, GPS data indicate that the convergence between Nubia and Eurasia is absorbed completely, or by a large extent (2.1 mm/a), in the seismic belt located in the southern Tyrrhenian Sea (Hollenstein et al 2003;D'Agostino & Selvaggi 2004;Serpelloni et al 2007), whereas there is no active shortening between the Hyblean plateau and the Aeolian Islands. These pieces of evidence have led to infer the onset of a new tectonic regime, with the young Tyrrhenian lithosphere that has possibly started being subducted to the south, underneath Sicily (Goes et al 2004;D'Agostino & Selvaggi 2004;Faccenna et al 2005).…”

“…Wortel & Spakman 2000), and S-wave propagation from intermediate to deep earthquakes located within the Tyrrhenian slab indicates that S-waves could not efficiently reach many stations located in the Southern Apennines and western Sicily, on either side of the slab, because they were attenuated when travelling through the asthenosphere (Mele 1998). Theoretical work and laboratory models strongly suggest that tears within the subducted lithosphere play a major role in the dynamic behaviour of subducted slab, particularly in controlling the extent and velocity of trench retreat, together with slab width (Dvorkin et al 1993;Kincaid & Griffiths 2003;Funiciello et al 2006;Schellart et al 2007). The conceptual implications of slab tears have been widely applied to the tectonic evolution of the Mediterranean, with the slab window imaged by tomography in the southern Tyrrhenian as a chief example (Carminati et al 1998;Wortel & Spakman 2000;Argnani 2000;Faccenna et al 2004;Goes et al 2004;Rosenbaum & Lister 2004).…”

Moreover, recent studies on SKS splitting in the central Mediterranean show some indication of the toroidal flow that is expected on the western side of the Tyrrhenian slab to compensate for its rollback (Civello & Margheriti 2004;Faccenna et al 2005: Baccheschi et al 2007.…”

The evolution of the southern Tyrrhenian subduction has been possibly controlled by distinct episodes of slab break-off as indicated by a critical review of the geological literature and by the analysis of purposely acquired multichannel seismic profiles. Within the proposed interpretation the first episode occurred from 8.5 to 4.0 Ma and affected the segment of the slab located in the Sardinia Channel, causing the abandonment of the Adventure thrust front in western Sicily. The second episode occurred between 2.5 and 1.6 Ma, affecting the segment of slab located north of Sicily, and was preceeded by rifting in the Strait of Sicily. The space and time location of these episodes appear controlled by discontinuities pre-existing within the subducted African plate that trend at high angle to the advancing subduction front. These discontinuities delimit segment of subducted slab that can be affected by slab break-off and can act as wayouts for magma and mantle derived He. The major of these discontinuities, the Malta Escarpment, has been reactivated in the Quaternary as a trench-perpendicular tear (STEP faults). Ultimately, the hierarchy in strength of these trench-perpendicular features could have affected the timing and amount of trench retreat and backarc opening.

Mantle dynamics in the Mediterranean

et al. 2014

The Mediterranean offers a unique opportunity to study the driving forces of tectonic deformation within a complex mobile belt. Lithospheric dynamics are affected by slab rollback and collision of two large, slowly moving plates, forcing fragments of continental and oceanic lithosphere to interact. This paper reviews the rich and growing set of constraints from geological reconstructions, geodetic data, and crustal and upper mantle heterogeneity imaged by structural seismology. We proceed to discuss a conceptual and quantitative framework for the causes of surface deformation. Exploring existing and newly developed tectonic and numerical geodynamic models, we illustrate the role of mantle convection on surface geology. A coherent picture emerges which can be outlined by two, almost symmetric, upper mantle convection cells. The downwellings are found in the center of the Mediterranean and are associated with the descent of the Tyrrhenian and the Hellenic slabs. During plate convergence, these slabs migrated backward with respect to the Eurasian upper plate, inducing a return flow of the asthenosphere from the back-arc regions toward the subduction zones. This flow can be found at large distance from the subduction zones and is at present expressed in two upwellings beneath Anatolia and eastern Iberia. This convection system provides an explanation for the general pattern of seismic anisotropy in the Mediterranean, first-order Anatolia, and Adria microplate kinematics and may contribute to the high elevation of scarcely deformed areas such as Anatolia and eastern Iberia. More generally, the Mediterranean is an illustration of how upper mantle, small-scale convection leads to intraplate deformation and complex plate boundary reconfiguration at the westernmost terminus of the Tethyan collision.
