Description
| - We image anisotropic structure of the upper mantle beneath the Northern Apennines based on body-wave data collected during the RETREAT experiment (2003-2006). Joint analysis of anisotropic parameters evaluated from independent data setsteleseismic P-wave travel times and shear-wave splittingallows us to identify regions of different fabrics both in the mantle lithosphere and in the sublithospheric mantle. We recognize three regionsthe Tyrrhenian, Adriatic, and Transitionwith their own anisotropic characteristics. The slab-parallel flow prevails in the sublithospheric mantle beneath the thin Tyrrhenian plate, while nearly slab-perpendicular orientation of the high velocities dominates on the Adriatic side of the region. The asthenospheric-flow pattern excludes a simple corner-flow model to fit the fabric of the upper mantle in the syn-convergent extensional tectonics and suggests the end of the subduction roll-back. We map fossil anisotropy with inclined symmetry axes within two domains of the thick continental Adriatic lithosphere.
