North Western Sicily offshore in the frame of the marine CARG Project. Main rsults

Carte marine e rischi geologici

The investigations carried out by the "Gruppo di Geologia Marina" of the Palermo University in the framework of the CARG project, have been focused on the marine sectors between the Egadi Islands offshore and the Cefalù Basin (NW Sicilian offshore). The research activities have yielded new results on the following fields: (i) sedimentation and coastal dynamics, (ii) sea bottom cartography and mapping of submerged structures, (iii) morpho-bathymetry and geological risk assessment

Submarine Slope Failures Along the Northern Sicilian Continental Margin (Southern Tyrrhenian Sea) and Possible Implications for Geo-Hazard

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…

Potential Cyclic Steps in a Gully System of the Gulf of Palermo (Southern Tyrrhenian Sea)

Multibeam bathymetric data revealed the occurrence of atrain of bedforms along a gully system in the Gulf of Palermo, Southern Tyrrhenian Sea. The observed gullies, located in the westernmost sector of the Gulf of Palermo, incise the outer shelf at a depth of 120 m and converge at the Zafferano Canyon, connecting to the Palermo Basin at a the depth of 1300 m. Bedforms develop along these gullies and along the thalweg of the canyon, displaying an average wavelength of 200 m, with maximum values of 340 m. Their gully floor location combined with their wave length, upslope asymmetry and crescent shape point to a possible cyclic steporigin of these bedforms. Preliminary numerical modeling sugge…

Foglio 593, Castellammare del Golfo

Il Foglio 593 “Castellammare del Golfo” della Carta Geologica d’Italia in scala 1:50.000 è stato realizzato nell’ambito del Progetto CARG con i fondi della Legge 305/89, con una convenzione tra Servizio Geologico Nazionale (ora ISPRA) e la Regione Siciliana. Il Foglio “Castellammare del Golfo” ricopre un settore dell’ estremità nordoccidentale della Sicilia e comprende le aree marine del Golfo del Cofano, della Baia di San Vito e della porzione centro-occidentale del Golfo di Castellammare, e quelle emerse costituite dalla dorsale dei Monti di Capo San Vito, dall’ampio settore collinare di Monte Luziano e Monte Bosco, dal massiccio di Monte Inici e dai pianori della Piana di Castellammare, …
