“…The Late Messinian and Zanclean-Piacenzian contractional/transpresional tectonic events resulted in generalized uplift, and associated slope oversteepening, both triggering gravity sliding towards the basin. In contrast, the phase of tectonic quiescence recorded in the Calabrian can be correlated with extensional episodes affecting the basin, concomitant with the spreading of the Tyrrhenian Sea and SE migration of the Calabrian Arc 19 . The reactivation of the gravitational phenomena, also involving the recent units, is likely to have been promoted by rapid regional uplift since the Middle Pleistocene (1cm /My), which may have increased the slope gradient of the sea oor towards the Ionian Sea 39,41 .…”

“…Slope instability was also promoted by another similar contractional/transpressional tectonic event between the Zanclean and the Piacenzian. This tectonic event was linked to a temporary pause of the Calabrian Arc migration, due to the convergence between the Calabrian accretionary system and the continental crust of the Apulian margin [34][35][36][37][38][39] , simultaneously with a temporary spreading interruption or slowdown in the Tyrrhenyan back-arc basin 19,41 . The Late Messinian and Zanclean-Piacenzian contractional/transpresional tectonic events resulted in generalized uplift, and associated slope oversteepening, both triggering gravity sliding towards the basin.…”

“…In the central Mediterranean region, an area subjected to large gravitational collapse is the Crotone Basin, a Neogene to Quaternary forearc depocenter located on the Ionian sector of the Calabrian Arc, in Southern Italy [14][15][16][17][18][19][20][21][22][23][24] . The stratigraphy of the Crotone Basin is closely linked to the Calabrian Arc kinematics, which recorded alternating phases of forward migration of the Arc, associated with basin subsidence, and collision between the Arc and the adjacent plates, associated with the formation of stratigraphic unconformities 19 (Figs. 1, 2 and Tab.…”

Seismic reflection (2D/3D), borehole and bathymetric data have led to the recognition of a new gravitational complex in the Squillace Embayment. Named as Squillace Complex, it has a NE-striking headwall connected to a basal detachment zone formed between Messinian evaporites and Tortonian shales. Its geometry changes to a W to E predominant movement in its toe region. The Squillace Complex is marked by the presence of sinuous and continuous seafloor scarps just a few kilometers offshore (minimum distance 1.5 km), which occur over a lobate-shaped elongated morphological high. Seismic-well ties show that the complex initiated its movement in the Zanclean and continued for ~ 2 Ma into the Gelasian, with an average rate of 1.6 mm /y. Movement ceased in the Calabrian but resumed soon later during Middle Pleistocene, until the present day, at a relative slower rate of 0.4 mm/y. The onset of gravitational collapse in the Squillace Complex is correlated with discrete contractional/transpressional events, under episodes of basin shortening and temporary stopping of Calabrian Arc migration, as well as during episodes of tectonic uplift after 0.45 Ma. Conversely, its arrest during the Calabrian is linked to slab rollback and subduction of the Ionian plate under the arc.

“…In all of the basins, the substrate units (dominantly crystalline) are sharply cut by a basal erosional unconformity and covered by a transgressive Serravallian/Tortonian Pre-Evaporitic Unit that reaches a maximum thickness of ca 300 m (in the Crotone Basin; Zecchin et al, 2018;Zecchin et al, 2020). This unit is made of conglomerates and sandstones grading upward into deeper marine Tortonian to Early Messinian clays covered by finely laminated diatomites (Rao et al, 2006).…”

The onset of the Messinian Salinity Crisis in the central Mediterranean recorded by pre‐salt carbonate/evaporite deposition

The Calcare di Base is a carbonate/evaporitic unit formed before the deposition of the massive halite bodies in the main depozones of the Mediterranean region, and has been at the centre of a fiery debate between different 'schools of thought' about its genesis, environmental conditions and timing of deposition. It crops out extensively in Southern Italy, across Neogene basins located on the Tyrrhenian and Ionian margins of northern Calabria, where it was studied through a detailed facies and stratigraphic analysis that revealed the presence of a continental/shallow-marine to slope system, active during the onset of the Messinian Salinity Crisis. During the Calcare di Base deposition, an arid climate regime with intermittent humid phases occurred with a precession forced cyclicity, facing an overall generally cold climatic period. During arid periods, stressed environmental conditions permitted the establishment of widespread microbial-mediated carbonate production, frequently associated with evaporitic (gypsum-dominated) deposition, along a sabkha-type environment with extensive salinas and hypersaline coastal lagoons grading seaward into a carbonate/evaporite shallow-marine shelf. This is testified to by microbial boundstones and dissolution breccias commonly associated with nodular gypsum and arenites affected by desiccation, typically forming metre-scale shallowing-upward peritidal cycles. Seaward, gravity flow deposits are interpreted as re-sedimented shelf limestones, defining a slope apron. Mixed carbonate/evaporite megabreccias and disorganized floatbreccias were deposited along the upper slope, whereas soft deformation with slides, slumps and channelized turbidites further developed along the lower slope to basin. During the humid climate episodes, that affected the platform system with a precession-forced cyclicity, the carbonate production was reduced together with the evaporitic deposition, leading to the widespread deposition of marlstones and fine to coarse siliciclastic deposits.

The knowledge of the territory that people inhabit, the awareness of the geological heritage value and its management are aimed both at the benefit of local socio-economic sustainable development goals and at promoting geopark-inclined geotourism through actions which identify potential geosites or enhance those already assessed. The objective of this study is focused on the geoheritage exploration of the Sila massif area, in southern Italy, in order to illustrate the high “geological diversity” like first step for inherent potential geotourism. The Sila landscape exhibits a rich geodiversity to give value, but it is poorly known to the public, although it has been and is the subject of many national and international scientific works. The focus of this work is to enhance the geological, geomorphological and landscape uniqueness of a Sila area, characterized by the presence of a wide range of weathering products and morphologies as a result of geological and geomorphological events and processes, in a variety of temporal and spatial scales, which have an influence on the development and evolution of reliefs and landscape, giving rise to the three geosites: Sila Spheroidal Boulder Field Geosite, Sila Sand Geosite and Sila Paleosols Geosite. These sites of geological interest were subjected to quantitative assessment in terms of the scientific, educational, touristic values and degradation risk of geosites.
