“…The development of the Central Mediterranean orogenic system was referred by several authors [e.g., Patacca et al ., ; Doglioni , ] to the southern Apennines thrust propagation toward the stable foreland. Previous works of the Central Mediterranean orogenic system analyzed separately its sectors, namely, Apulia foreland [ Doglioni et al ., ; Argnani et al ., ; Butler , ; Milia et al ., ], Southern Apennines accretionary prism [e.g., Lentini et al ., ; Cello and Mazzoli , ; Patacca and Scandone , ], and Tyrrhenian Sea back‐arc basin [e.g., Kastens and Mascle , , Sartori , , ; Milia et al ., , , ]. The recognition of significant strike‐slip faults that overprinted the accretionary prism and the Apulia slab records the collisional orogenic stage [e.g., Cello and Mazzoli , ; Monaco et al ., ; Catalano et al ., ].…”

“…Our tectonic reconstruction adopts the migration of the outer front of the southern Apennines from the late Messinian proposed by Vitale and Ciarcia [] and the architecture of extensional and strike‐slip faults of the Tyrrhenian region from Milia et al . [, , ] and Milia and Torrente []. In the end, our model includes original stratigraphic and tectonic data on the Apulia foreland and southern Apennines.…”

“…The Tyrrhenian Sea evolved from a fore‐arc extensional region in the lower Miocene and was characterized by a complex physiography with several subbasins [ Milia and Torrente , , ; Milia et al ., ]. Notably, the present physiography is principally a product of the Pliocene‐Quaternary back‐arc evolution that led to the formation of two large bathyal basins (Vavilov and Marsili basins) and several peri‐Tyrrhenian basins (Figure a).…”

“…The convergence of the Africa and Eurasian plates, during the migration of the Calabria subduction zone [e.g., Malinverno and Ryan , ; Jolivet and Faccenna , ; Wortel and Spakman , , and references therein], led to the opening of the central Mediterranean, which has been interpreted as a response to a continuum back‐arc extension from NW toward SE from the opening of Liguro‐Provençal basin to the Present Tyrrhenian Sea basin. However, if we consider the position of the middle upper Miocene volcanic arc off Sardinia, we can postulate that the coeval sedimentary basins developed in the central Mediterranean as fore‐arc extensional basins during the progressive collision with the African plate and before the Tyrrhenian Pliocene‐Quaternary high stretching back‐arc opening [ Milia and Torrente , ; Chen et al ., ; Milia et al ., ]. We believe that the entire Calabria terrane should be included within the early‐stage extensional Tyrrhenian rifting as the paleogeographic reconstruction of the Serravallian‐Tortonian Calabria‐Sardinia breakup suggests.…”

“…Notably, the present physiography is principally a product of the Pliocene‐Quaternary back‐arc evolution that led to the formation of two large bathyal basins (Vavilov and Marsili basins) and several peri‐Tyrrhenian basins (Figure a). Recent tectonostratigraphic analyses of the sedimentary basins of the southern Tyrrhenian Sea [ Milia et al ., , , , , ] reconstructed a polyphase extensional evolution with location of rifting and kinematic changes over time.…”

In the Central Mediterranean the Africa‐Eurasia convergence led to the development of complex orogenic systems and back‐arc basins. Throughout Pliocene‐Quaternary times the Southern Apennines accretionary prism migrated toward the Apulia foreland and, contemporaneously, the Tyrrhenian Sea back‐arc basin opened. In this study, we investigated the offshore of the southern Apulia foreland and the Southern Apennines. Using seismic reflection profiles and well data in a dedicated GIS software, we made a detailed stratigraphic analysis, reconstructed the structural pattern, and built 2‐D geological models of the main geological surfaces. The structure of the Apulia region formed during two main tectonic stages: lower Pleistocene complex extensional faulting developed in a transtensional regime and middle‐upper Pleistocene transpression/shortening. The Southern Apennines accretionary prism developed through the Pliocene‐early lower Pleistocene and was overprinted by late lower Pleistocene‐middle Pleistocene NW‐SE sinistral faults. Through linking new data from the accretionary prism and the foreland with previous information from the Tyrrhenian Sea back‐arc, we provide an original interpretation for the relationships between the various provinces that make the Central Mediterranean crustal puzzle and reconstruct the main phases of the evolution of its Pliocene‐Quaternary orogenic cycle. We recognized collisional stages of uncoupled plates, followed by late lower‐middle Pleistocene postcollisional stages of coupled continental plates. This Pleistocene plate reorganization of Central Mediterranean was probably due to the rupture of the Apulia/Ionian slab or to NNW intraplate shortening transmitted from Africa.

Transfer zones in an oblique back-arc basin setting: Insights from the Latium-Campania segmented margin (Tyrrhenian Sea)

New multichannel seismic reflection profiles were acquired to unravel the structure of a portion of the eastern margin of the Tyrrhenian basin. This extensional feature is part of an Oligocene to Present back‐arc basin in the hangingwall of the west directed Apennines subduction system. The basin provides excellent conditions to investigate the early stage processes leading to the development of rifted passive margins and to the emplacement of oceanic crust in an oblique setting. The interpreted post‐stack‐migrated seismic profiles highlight the geometry and kinematics of the Pontine escarpment that connects the Latium‐Campania continental margin to the Vavilov basin. The latter is the main feature of the area, related to the early Pliocene extension of the Tyrrhenian Sea. Several morphological variations are pointed out along strike, mirroring different structural settings of the margin itself: a steeper margin to the north corresponds to high‐angle possibly transtensional faults, whereas a smooth slope in the southern portion corresponds to several more distributed listric faults. This work contributes to the understanding of the interplay between extensional and transtensional tectonics along the margins of an oblique back‐arc basin.
