Zusammenfassung |
In this study we present a new regional tomography model of the upper mantle
beneath Italy and the surrounding area derived from the inversion of travel times
of P and S waves from the updated International Seismological Centre (ISC) catalogue. Beneath Italy, we identify
a high-velocity anomaly which has the appearance of a long, narrow
"sausage" with a steeply dipping part down to a depth of 400 km and then
expanding horizontally over approximately 400 km. Rather than to interpret
it as a remnant of the former Tethyan oceanic slab, we consider that it is
made up of the infra continental lithospheric mantle of Adria, which is
progressively delaminated, whereas its overlying crust becomes progressively
accreted into the Apenninic tectonic wedge. |
