“…It extends, parallel to the southern coast of Sicily, from the northeastern side of the Nameless Bank to the western border of the Hyblean Plateau, showing a maximum bathymetric depth of about 900 m bsl. The basin formation is related to the flexure of the carbonate substrate of the foreland, due to loading of the Gela Nappe (Catalano et al 1996).…”

In order to unravel the tectonic evolution of the north-central sector of the Sicily Channel (Central Mediterranean), a seismo-stratigraphic analysis of single-and multichannel seismic reflection profiles has been carried out. This allowed to identify, between 20 and 50 km offshore the central-southern coast of Sicily, a *80-km-long deformation belt, characterized by a set of WNW-ESE to NW-SE fault segments showing a polyphasic activity. Within this belt, we observed: i) Miocene normal faults reactivated during Zanclean-Piacenzian time by dextral strike-slip motion, as a consequence of the AfricaEurope convergence; ii) releasing and restraining bend geometries forming well-developed pull-apart basins and compressive structures. In the central and western sectors of the belt, we identified local transpressional reactivations of Piacenzian time, attested by well-defined compressive features like push-up structures and fault-bend anticlines. The reconstruction of timing and style of tectonic deformation suggest a strike-slip reactivation of inherited normal faults and the local subsequent positive tectonic inversion, often documented along oblique thrust ramps. This pattern represents a key for an improved knowledge of the structural style of foreland fold-and-thrust belts propagating in a preexisting extensional domain. With regard to active tectonics and seismic hazards, recent GPS data and local seismicity events suggest that this deformation process could be still active and accomplished through deep-buried structures; moreover, several normal faults showing moderate displacements have been identified on top of the Madrepore Bank and Malta High, offsetting the Late Quaternary deposits. Finally, inside the northern part of the

“…Onlap of Pleistocene sediments onto the thrust front suggests that no significant compressive deformation occurred after the lower In the external western Maghrebides (thrusts derived from the deformation of the Trapanese to Saccense domains), the earliest compressive tectonic episodes are assumed to be Tortonian in age [Catalano et al, 1996] and to continue during the Plio-Pleistocene as well [Vitale, 1990] [ 1980,1990], Grasso et al [1983,1987] Figure 3). These authors also referred the rapid uplift of recent deposits to the activity of the ramp anticlines.…”

“…In this continental subduction collisional complex, several tectonic and stratigraphic elements are differentiated ( Fig. 1; Catalano et al 1996Catalano et al , 2002Catalano et al , 2013 and references therein): 1) A complex consisting of a SE-vergent fold and thrust belt, which is composed of a "Tethyan" element (Sicilidi units) and an African element (Sicilian units); 2) The Sicilidi units are represented by repeated imbricate slice stack deriving from the deformation of Upper Jurassic-Oligocene basin carbonates and sandy mudstones located in the Sicilide facies domain; 3) The Sicilian units are characterized by allochthonous tectonic units deriving from the deformation of Permian-Miocene deepwater carbonates and bedded cherts deposited in the Imerese and Sicanian basins (Basilone et al 2014; and Mesozoic-Miocene shelf-to-pelagic carbonates located in the Panormide, Trapanese, Saccense, and Iblean-Pelagian carbonate platform or seamount facies domain; 4) upper Oligocene-middle Miocene turbiditic deposits (Numidian flysch) cover the Sicilide, Imerese, and Panormide rock successions; lower-upper Miocene deformed foreland marls cover the Sicanian, Trapanese, and Saccense rock successions; OligoceneQuaternary foreland open shelf carbonates cover the Iblean-Pelagian rock successions; 5) A thick pack consisting of middle Miocene-Pleistocene foreland, wedge-top and foredeep basin deposits (terrigenous, evaporitic, and clastic carbonate rocks), which largely form the Gela Thrust System; 6) A deepseated and buried foreland, slightly deformed, crops out only in the south-eastern end of Sicily and in the floor of the Sicily Channel.

“…The tectonic evolution of the western Sicily belt was a progressive accretion of thrust sheets (Catalano et al 2000) and duplex formation (Catalano et al 1996), combined with the clockwise rotation of the allochthonous blocks (Oldow et al 1990;Speranza et al 2003).…”

This paper proposes a morphoevolutionary model for western Sicily. Sicily is a chain-foredeep-foreland system still being built, with tectonic activity involving uplift which tends to create new relief. To reconstruct the morphoevolutionary model, geological, and geomorphological studies were done on the basis of field survey and aerial photographic interpretation. The collected data show large areas characterized by specific geological, geomorphological, and topographical settings with rocks, landforms, and landscapes progressively older from south to north Sicily. The achieved results display: (1) gradual emersion of new areas due to uplift, its interaction with the Quaternary glacio-eustatic oscillations of the sea level, and the following production of a flight of stair-steps of uplifted marine terraces in southern Sicily, which migrates progressively upward and inwards; in response to the uplift (2) triggering of down-cutting processes that gradually dismantle the oldest terraces; (3) competition between uplift and down-cutting processes, which is responsible for the genesis of river valleys and isolated rounded hills in central Sicily; (4) continuous deepening over time that results in the exhumation of older and more resistant rocks in northern Sicily, where the higher heights of Sicily are realized and the older forms are retained; (5) extensional tectonic event in the northern end of Sicily, that produces the collapse of large blocks drowned in the Tyrrhenian Sea and sealed by coastal-marine deposits during the Calabrian stage; (6) trigger of uplift again in the previously subsiding blocks and its interaction with coastal processes and sea level fluctuations, which produce successions of marine terraces during the Middle-Upper Pleistocene stages.
