Quaternary marine and continental unconformity-bounded stratigraphic units of the NW Sicily coastal belt
In the coastal sector of NW Sicily, the regional correlation of relevant unconformities recognised within the Quaternary sedimentary successions allowed the mapping of seven unconformity-bounded stratigraphic units (UBSUs). The regional unconformities are marine or subaerial erosional surfaces, as well as non-depositional surfaces, locally marked by paleosoils. The erosional surfaces were produced from marine abrasion, surface water overland/concentrated flow, river erosion, karst solution, mass movement, or wind erosion. The main lithofacies of the Quaternary UBSUs consist of: (a) marine and coastal bioclastic calcarenites, (b) aeolian sandstones, (c) river deposits, (d) colluvial deposits…
The geographic information in the assessment of geohazard in the marine environment
Slope instability and erosion, mass transport, volcanic and tectonic activity, fast sediment accumulation fluid escape are the main processes responsible for the geohazard in marine environment. A major knowledge about the geological setting of the offshore areas and related processes can be crucial to assess and manage the potential geological risks. High resolution morphobathymetric surveys, yielded in the frame of the MaGIC project (Marine Geohazards along the Italian Coasts), integrated with previously acquired data, single-channel seismic reflection profiles, backscatter data and sediments sampling, allow to define the geomorphological, stratigraphic and structural features in the offs…
Mountain building in NW Sicily from the superimposition of subsequent thrusting and folding events during Neogene: structural setting and tectonic evolution of the Kumeta and Pizzuta ridges
We present a 1:25.000 scale geological map of the Kumeta-Pizzuta ridge in north-western Sicily (Italy), achieved by integrating stratigraphic, structural and geophysical data. In this area, the tectonic edifice results from the piling-up of deep-water-, carbonate platform- and pelagic platform-derived tectonic units (Imerese and Sicilide, Panormide and Trapanese domains, respectively) resulting from deformations of the former southern Tethyan continental margin. The structural setting shows interference of tectonic events, different types of structural styles and different scales of deformational patterns. Early overthrust of the Imerese on the Trapanese units (since the late Serravallian) …
VIGOR: Sviluppo geotermico nelle Regioni della Convergenza. Progetto VIGOR – Valutazione del Potenziale Geotermico delle Regioni della Convergenza, POI Energie Rinnovabili e Risparmio Energetico 2007-2013
Progetto MAGIC: “L’informazione territoriale nella valutazione del rischio geologico in ambiente marino”. . In: Workshop GIS Day: "GIStales: di dati, persone e strumenti”.
MaGIC è un progetto quinquennale (2007-2012) finanziato dal Dipartimento Nazionale della Protezione Civile per l'acquisizione di dati morfobatimetrici ad alta risoluzione. Lo scopo principale del progetto è quello di definire e rappresentare i principali elementi morfologici dei fondali marini, in particolar modo quelli derivanti da dinamiche morfo-sedimentarie che implicano mobilità e/o instabilità dei sedimenti e conseguenti situazioni di pericolosità per le infrastrutture e le aree costiere urbanizzate. I rilievi morfobatimetrici vengono realizzati con un sistema ecoscandaglio radiale multifascio (Multibeam echosounder systems) calibrato ad hoc nell’area di lavoro e corretto in velocità …
