In this paper we present an integrated crustal model across the southern Tyrrhenian continental margin that evolved from compressional to extensional tectonics. The seismic data set combined and constrained with surface geologic data and gravity modeling provides a three layers lithospheric model. In the Southwestern half of the velocity model, across the Tyrrhenian margin, the upper crust is characterized by lateral velocity and thickness variability caused by the transition from oceanic to transitional to thinned continental crust controlled by the opening of the Tyrrhenian back arc basin. Quite clear wide angle reflections (PiP) from the top of the lower crust are present in the receiver gathers, constraining the thickness of the upper crust. Thickness and velocity of the lower crustal layer are defined by prominent PmP phases which travel extensively through this layer. Pn first arrivals are observed only on few traces of the record sections and account for a \u00ABTyrrhenian\u00BB upper mantle velocity of 7.8 km/s The prolongation of the \u00ABTyrrhenian Moho\u00BB northeastward is constrained by PmP phases observed on some receiver gathers, where later phases are also evidenced. We interpreted these late arrivals as reflected phases of the crust/mantle boundary of the downgoing Adriatic slab. Pn phases observed on the Gargano stations, the more clear and complete of the entire data set, constrain an Adriatic upper mantle velocity of 7.9 km/s and are also consistent with a Tyrrhenian upper mantle of 7.8 km/s. The crustal model developed from the wide-angle data set was indipendently tested using Bouguer gravity anomalies. The crustal velocity model was used as a direct input for the gravity modeling. Being the available data compilation related to large scale gravity anomalies (average grid dimension of 3\u00D73 km), only three layers have been modeled (upper and lower crust, upper mantle), taking into account the Vp lateral variations."@en ; prodottidellaricerca:prodottoDi istituto:CDS028 , modulo:ID1963 ; pubblicazioni:autoreCNR unitaDiPersonaleEsterno:ID4236 , unitaDiPersonaleInterno:MATRICOLA39358 , unitaDiPersonaleInterno:MATRICOLA4397 , unitaDiPersonaleInterno:MATRICOLA2920 .
