“…This is in disagreement with other studies which have documented the individuation of this narrow linear basin starting from the Late Pliocene-Early Pleistocene e.g. : [4,7,50,61,123,125,126]. The onset of the daily inversion of strong tidal currents between the Tyrrhenian Sea and the Ionian Sea occurred most probably later, because no tide-influenced facies are documented from deposits that are older than the Middle Pleistocene.…”

“…Plio-Pleistocene cool-water biocalcarenitic-dominated sediments, forming isolated or clustered coastal wedges, represent one of the most common types of deposits crop-ping out along the northeastern coast of Sicily (Southern Italy) [1][2][3][4][5][6][7][8][9]. These deposits are mainly formed by mixed siliciclastic and bioclastic fractions derived from the local bedrock units and skeletal fragments.…”

Biostratigraphic analyses carried out on siliciclastic/bioclastic deposits discontinuously cropping out along the Ionian flank of NE Sicily, indicate that they form two sedimentary events of Early and Middle Pleistocene, respec tively. Vertical facies successions, showing transgressive trends, suggest that sedimentation occurred within semi-enclosed marine embayments, where sublittoral coastal wedges developed on steep ramp-type shelves. Sediments accumulated in shoreface to offshore transitions along steep bottom profiles. This depositional scenario was strongly conditioned by the tectonic activity of the rift zone linking Western Calabria and Eastern Sicily. The effects of glacio-eustatism were also recognized. According to our reconstruction, the study area was controlled by a transfer fault system which affected the coastal margin producing major episodes of uplift and subsidence. Block-faulting was responsible for significant cannibalization and recycling of older deposits during the Middle Pleistocene. Such a tectonic setting can be considered the precursor scenario for the formation of the Messina Strait between Calabria and Sicily. This narrow, linear basin influences the hydrodynamic setting of sublittoral deposits along the Ionian coast of Sicily, giving rise to strong flood/ebb tidal currents. The uppermost part of the Middle Pleistocene succession recognized in the study area is indeed dominated by tide-influenced associations of sedimentary structures which most likely record the first stage of the opening of this ‘seaway’ of the central Mediterranean Sea.

“…The sandy matrix of the neptunian dyke parabreccias is texturally similar to coeval upper-shoreface sand, coarser than the host sandstone, which supports the notion of a contemporaneous derivation by wave action. The development of neptunian dykes signifies extensional strain and is typically associated with normal faults (Montenat et al, 1991;Cozzi, 2000). The hanging wall in the present case was likely fractured due to its internal relaxation stresses (Montenat et al, 2007).…”

“…The origin of neptunian dykes is widely attributed to seismic activity (Playford, 1980;Winterer and Bosellini, 1981;Lehner, 1991;Montenat et al, 1991;Cozzi, 2000), although similar features have also been reported from the surfaces of submarine slides (Winterer et al, 1991;Winterer and Sarti, 1994). The formation of open fissures is related to extension in cohesive or consolidated sediment (Moretti and Sabato, 2007), caused by such factors as a surficial stretching associated with the strain relaxation of fault scarps, slide extension gashes, diapir rising, or overloading (Montenat et al, 2007).…”

This study presents aggradation rates supplemented for the first time by carbonate accumulation rates from Mediterranean cold-water coral sites considering three different regional and geomorphological settings: (i) a cold-water coral ridge (eastern Melilla coral province, Alboran Sea), (ii) a cold-water coral rubble talus deposit at the base of a submarine cliff (Urania Bank, Strait of Sicily) and (iii) a cold-water coral deposit rooted on a predefined topographic high overgrown by cold-water corals (Santa Maria di Leuca coral province, Ionian Sea). The mean aggradation rates of the respective cold-water coral deposits vary between 10 and 530 cm kyr À1 and the mean carbonate accumulation rates range between 8 and 396 g cm À2 kyr À1 with a maximum of 503 g cm À2 kyr À1 reached in the eastern Melilla coral province. Compared to other deep-water depositional environments the Mediterranean cold-water coral sites reveal significantly higher carbonate accumulation rates that were even in the range of the highest productive shallow-water Mediterranean carbonate factories (e.g. Cladocora caespitosa coral reefs). Focusing exclusively on cold-water coral occurrences, the carbonate accumulation rates of the Mediterranean coldwater coral sites are in the lower range of those obtained for the prolific Norwegian coral occurrences, but exhibit much higher rates than the cold-water coral mounds off Ireland. This study clearly indicates that cold-water corals have the potential to act as important carbonate factories and regional carbonate sinks within the Mediterranean Sea. Moreover, the data highlight the potential of cold-water corals to store carbonate with rates in the range of tropical shallow-water reefs. In order to evaluate the contribution of the cold-water coral carbonate factory to the regional or global carbonate/carbon cycle, an improved understanding of the temporal and spatial variability in aggradation and carbonate accumulation rates and areal estimates of the respective regions is needed.
