New Constrains on Upper Mantle Flow at Regional Scales.
The regional mantle flow beneath the westernmost Mediterranean basin and its transition to 12 the Atlantic domain is addressed by inspecting the anisotropic properties of the mantle. More 13 than 100 new sites, from the Variscan core of Iberia to the northern rim of the Western 14 African Craton, are now investigated using the data provided by different temporary and 15 permanent broad-band seismic arrays. Our main objective is to provide a larger regional 16 framework to the results recently presented along the Gibraltar Arc in order to check the 17 validity of the different geodynamic interpretations proposed so far. 18 19
