Permian-Cenozoic deep-water carbonate rocks of the Southern Tethyan Domain. The case of Central Sicily
2016
We present an integrated stratigraphy of the outcropping and buried Permian-Cenozoic deep-water carbonate successions, forming some of the tectonic units mostly buried beneath the Late Neogene sedimentary cover in the fold and thrust belt of Central Sicily. Three main successions, pertaining to the well known Lercara, Imerese and Sicanian domains, have been reconstructed on the basis of a detailed facies analysis, seismostratigraphic interpretation, bio -stratigraphy (mostly based on palynological data) and comparison between outcropping and subsurface deep-water sediments. The main results reveal a continuous sedimentation of the deep-water Southern Tethyan Sicilian succession since the Pe…
The buried Fold and Thrust Belt in Sicily: perspectives for future exploration.
2012
The study region is a part of the Sicilian-Maghrebian Fold and Thrust Belt (FTB), a segment of the Alpine collisional belt, recently described as a result of both post-collisional convergence between Africa and Europe and roll-back of the subduction hinge of the Ionian lithosphere. The region (extending in central Sicily from the Madonie Mountains. to the eastern corner of the Iblean-Pelagian foreland through the impressive NE-SW trending Tertiary clastic and evaporitic range of the Caltanissetta trough) is located in an area where the main thrust system disappears beneath a wedge of deformed Neogene deposits. Earlier studies have neglected the importance of the potential target for hydroca…
Fore-arc Deformation in the Paola Basin Segment (Offshore Western Calabria) of the Tyrrhenian‐Ionian Subduction System
2017
The 3D stratigraphic architecture and Late Neogene to Recent tectonic evolution of the Paola Basin (offshore western Calabria), a segment in the fore-arc of the Tyrrhenian‐Ionian subduction system, is reconstructed by using a grid of high-penetration reflection seismics. Oligocene to Messinian deposits are interpreted all along the profile. They tend to fossilize preexisting topography and reach the largest thicknesses between (fault controlled) basement highs. Plio‐ Quaternary deposits are found over the entire area and display variations in thickness and tectonic style. They are thicken up to 4.5 km in the depocenter of the basin, and decrease both in the east and west termination of the …

Francesco Fichera e il Palazzo delle Poste per Noto: studio grafico su un edificio mai realizzato
2022
Si può parlare di dialogo in architettura? Il disegno può essere considerato come la traduzione in forma grafica dei rapporti dialogici in architettura e tra architettura e città? Con questo scritto si tenterà si rispondere ai due quesiti appena formulati attraverso lo studio del caso di un edificio non realizzato dell’architetto catanese Francesco Fichera (1881-1950) per la città emblema del barocco siciliano, Noto: il Palazzo delle Poste e Casa Littoria nella centralissima piazza del Municipio. L’approfondimento sulla documentazione progettuale ritrovata e la successiva fase di ridisegno critico restituiscono una possibile chiave di lettura su un metodo compositivo fortemente ancorato a r…
Grafica multimodale
2010
Negli ultimi tempi la grafica si è evoluta in direzione digitale: il pixel ha sostituito la stampa, e i software hanno ridotto il corredo fisico tradizionalmente impiegato dai progettisti, dalla matita ai complessi macchinari tipografici. Ciò nonostante, anzi proprio per questo, non v’è stato alcun cambiamento di rotta; al contrario, s’è ripetuto quanto di più ovvio: la grafica ha risposto allo sviluppo tecnologico. Agli inizi del 20° sec. le avanguardie storiche hanno condotto una straordinaria sperimentazione (tipo-)grafica, imperniando, non a caso, la propria spinta creativa sulle nuove tecnologie. Le si ritrovano, qua e là, di riflesso, nel corso di questo saggio e in molta grafica odie…

The Monte San Nicola section (Sicily) revisited: A potential unit-stratotype of the Gelasian Stage
2022
The Monte San Nicola area (Southern Sicily) offers a spectacular exposure of open-marine sediments that were employed in 1998 for defining the Global Stratotype Section and Point (GSSP) of the Gelasian Stage (Upper Pliocene). After the lowering of the Pliocene/Pleistocene boundary to ca. 2.6 Ma in 2010, the Gelasian GSSP has been redefined as the base of both the Pleistocene Series and the Quaternary Period, which increased its importance and visibility within the scientific community. However, documentation on the Monte San Nicola reference section is still sparse. In the light of its renewed status, we decided to undertake a complete revision of the Gelasian Stage in its type area, in ord…
Geohazard assessment of the north-eastern Sicily continental margin (SW Mediterranean): coastal erosion, sea-level rise and retrogressive canyon head…
2022
Coastal dynamics are the result of several processes controlling the balance between sediment input and output over time. The beach system is not always able to maintain a neutral coastal balance due to natural and anthropogenic causes. We present an integrated marine geology, geomorphological and sea-level rise analysis in the coastal sector between Torre delle Ciavole and Capo Calavà (North-Eastern Sicily, Italy).This sector is characterized by high uplift rates and frequent seismicity (mainly generated by the very active Vulcano-Tindari Fault System), promoting the development of mass-wasting processes in the coastal and offshore sectors. A main erosive feature observed in the area is th…
