“…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).…”

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.

“…Schiattarella et al (2006) hypothesized in Tyrrhenian side of the Southern Apennines chain an extensional tectonics event younger than upper Tortonian and older than Pliocene. Besides proofs of Messinian extension are documented by the Stilo supradetachment basin (Calabria offshore) that records an increase in extensional rate and isostatic and flexural uplift (Milia and Torrente, 2015b). Within this geological framework we postulate that the low-angle normal faults present onshore of the SCM were possibly associated to the Messinian forerarc extension.…”

The Southern Campania Margin (SCM) represents a key area of the Central Mediterranean because it records all the rifting stages of the Tyrrhenian Sea. The interpretation of a seismic dataset calibrated with deep wells and outcrops, using seismic stratigraphy and structural geology methods in a dedicated Geographic Information System (GIS) environment, the seismic depth conversion, the generation of 2-D and 3-D models led to the reconstruction of a polyphased tectono-stratigraphic evolution of the SCM. During the early stage of Tyrrhenian opening a terrigenous transtensional Basin (Langhian-Tortonian Cilento Basin) formed on the Liguride accretionary prism adjacent to the Calabria crystalline terrane. In the SCM the Liguride thrust sheets tectonically overly the Apennine Platform units and both these nappes have been dismembered by Quaternary faults. Three rifting stages, not homogeneously distributed, affected the region since the Lower Pleistocene. They are associated to the deposition of a thick Quaternary succession (A, B and C units). During these Pleistocene stages there was an abrupt change of the extension direction (from NE-SW to NW-SE) accompanying a change of the nappe transport direction of the Southern Apennines. The construction of balanced sections using dedicated software, permitted us to recognize the true geometry of the faults and compute the amount of Quaternary extension of the SCM that results comparable to those calculated for other sectors of the Tyrrhenian margin and further extensional regions worldwide.

The direction of extension and the architecture of the Messinian basins of the Central Mediterranean region is a controversial issue. By combining original stratigraphic analysis of wells and seismic profiles collected offshore and onshore Calabria, we reassess the tectonic evolution that controlled the sedimentation and basement deformation during Messinian times. Three main deep sedimentary basins in the Calabria area record a Messinian succession formed by two clays/shales-dominated subunits subdivided by a halite-dominated subunit. The correlation with the worldwide recognized stratigraphic features permit to define the chronology of the stratigraphic and tectonic events. Three main rift basins that opened in a N-S direction have been recognized. On the contrary a fourth supradetachment basin opened toward the East. We found that the basin subsidence was controlled by two stages of activity of normal faults and that Messinian rift basins evolve in a deep-water environment. The overall pattern of extensional faults of the Central Mediterranean corresponds to normal faults striking parallel to the trench and normal faults striking at an oblique angle to the trench (Fig. 14). In particular in Campania and Calabria regions are present two rifts parallel to trench and an intervening rift orthogonal to the trench. We maintain that the recognized Messinian rift basins can be interpreted according to the “Double-door saloon tectonics”.
