I depositi quaternari nei fogli CARG della Sicilia nord occidentale: implicazioni climatiche, ambientali e tettoniche

Quaternary deposits within the National Geologic Maps of Northwestern Sicily: climatic, environmental and tectonic implications. In Northwestern Sicily, Quaternary continental, coastal and marine deposits outcrop. The occurrence of deposits enclosing lower and upper unconformity surfaces allowed to define several unconformity-bounded stratigraphic units (synthems). These units have been mapped in the several National Geologic Maps prepared in the frame of the CARG Project. Stratigraphic features of the Quaternary deposits and their relationship with marine/fluvial terraces, other landforms and tectonic structures suggest the presence of small and isolated sedimentary areas placed on structu…

Submarine Slope Failures Along the Northern Sicilian Continental Margin (Southern Tyrrhenian Sea) and Possible Implications for Geo-Hazard
2013
Mass wasting and downslope movements are common processes that have contributed to shape the northern Sicilian continental margin (southern Tyrrhenian Sea) since the Late Quaternary. Nevertheless, processes controlling their evolution are still partially unknown and a variety of geologic factors can be responsible for their formation. In this work we present an overview of the main mass wasting features (submarine canyons, landslides, debris flows) observed and mapped in different sectors of the northern Sicilian margin. The margin is characterized by a narrow, steep continental shelf (1-2°) and a very irregular and steep (6-8°) upper slope. The main aims of this work are: (1) to outline th…

un antico sistema di drenaggio sotterraneo. i "cunicoli borbonici di Petralia Sottana (Sicilia)
2017
Lo studio riguarda un intervento geotecnico in sotterraneo realizzato diversi secoli fa la cui esecuzione ha influenzato positivamente le condizioni di stabilità dei versanti contigui a una linea di impluvio che, attraversando il centro storico del comune di Petralia Sottana, ne minacciava la sicurezza.
Toward an update of the structural model in Italian submerged areas: contributions from the EMODnet Geology Project
2016
The European Marine Observation and Data Network (EMODNet) Project aims at the collection of as many existing data as possible on European Seas to be represented on digital maps at the 1:250,000 scale, accessible via web through a dedicated portal. It is articulated into different Lots concerning Bathymetry, Geology, Biology, Chemistry, Physics, Physical Habitats, Human activities. The Geology Lot is realized by a Consortium in which the Geological Survey of Italy is partner. EMODnet Geology requires the compilation of a number of layers subdivided into Work Packages (WP), referring to seafloor sediments grainsize, sedimentation rates, Quaternary geology, pre-Quaternary geology and stratigr…
