Bathy-morphological analysis of submarine canyons across the north-western Sicily continental slope

2016

We present here the results of the morpho-bathymetric analyses of the main submarine canyons along the upper slope off the north-western Sicily. This region developed during the Neogene as the transition area between the Sicilian fold and thrust belt and the Tyrrhenian basin realm. Along the upper slope, a dense network of submarine canyon develops from 80 m water depth up to more than 2000 m, showing a large variability of sizes and morphology. In this area submarine canyons play a crucial role related to the along-slope sedimentary transport and are among the most distinctive features of the submarine seascape. This study is based on a quantitative analysis of a high resolution multibeam …

GENESIS AND GEOMORPHOLOGICAL EVOLUTION OF DEEP-SEATED GRAVITATIONAL SLOPE DEFORMATIONS: AN EXAMPLE OF DATING IN WESTERN SICILY

2010

The study area lies in the westernmost part of the Sicani Mountain range where a superposition of SE-trending, stacked, geological bodies crops out. this structure is the result of transpressive tectonic phases of Miocene and Lower Pliocene age. The neo-autochthon outcrops are made up of clay–marly deposits of the Middle–Upper Pliocene, and of calcarenites of Pleistocene age. The extensional Quaternary tectonic phases later dissected and dismembered the original structure, thus involving the calcarenites that show clear, mainly NE–SW oriented dislocations. Such calcarenites, which have a total thickness of about 80 metres, overlap the Belice marly-arenaceous formation. This determined favou…

Deep-seated gravitational slope deformations in western Sicily: Controlling factors, triggering mechanisms, and morphoevolutionary models

2014

Abstract A study of deep-seated gravitational slope deformation (DSGSD) phenomena affecting areas of various geological and geomorphological settings in western Sicily is described. Western Sicily is underlain by a thin-skinned imbricate wedge of Meso–Cenozoic carbonate and siliciclastic rocks that formed by the stacking of several thrust nappes over the Iblean foreland. Locally, the original thrust sheets are folded and cut by high-angle faults. Large areas of western Sicily now display high relief energy due to Plio-Pleistocene block-faulting and uplifting, and the Quaternary morphogenetic phases are characterised by incision, thereby triggering widespread DSGSDs. To identify controlling …

Tra Palermo e Solunto: insediamenti, ambiente, paesaggio, viabilità e risorse in età antica

2020

This paper describes the hinterland between Palermo and Solunto (north-western Sicily). The focus is the distribution of settlements, linked to the geomorphological context, the potential resources and the ancient route system. The analysis ranges from the Archaic to the Middle Ages, when some relevant sites – both from an economic and strategic point of view – are part of the properties of the Teutonic Order. Some important routes cross the area, both in the SW direction, towards Monte Iato, and in the SE direction, towards the area of influence of the Greek colony of Himera. The analysis is carried out using toponymy and historical cartography, associated with the few archaeological data …

Prevalence of sexually transmitted infections and enteric protozoa among homosexual men in western Sicily (south Italy)

2012

Introduction. In recent years an increase in the number of sexu- ally transmitted infections (STIs) in men who have sex with men (MSM) has been reported in different industrialised countries. Because few epidemiological data on the STIs/MSM population in Sicily are available, a survey was conducted to assess the preva- lence of STIs/enteric protozoa and risky sexual behaviours among MSM in western Sicily. Methods. In 2010, 74 MSM with median age of 30 years old, were recruited via networks. All participants to the study were interviewed by anonymous self-administered questionnaire in order to collect social/demographic information, clinic data and STI-related risky sexual behaviours. After …

Sequence stratigraphy of a mesozoic carbonate platform-to-basin system in Western sicily

2009

Abstract Sequence stratigraphic studies of the Triassic through Paleogene carbonate successions of platform, slope and basin in western Sicily (Palermo and Termini Imerese Mountains) have identified a sedimentary cyclicity mostly caused by relative oscillations of sea level. The stratigraphic successions of the Imerese and Panormide palaeogeographic domains of the southern Tethyan continental margin were studied with physical-stratigraphy and facies analysis to reconstruct the sedimentary evolution of this platform-to-basin system. The Imerese Basin is characterized by a carbonate and siliceous-calcareous succession, 1200–1400m thick, Late Triassic to Eocene in age. The strata display a typ…

Interventi su volte sottili di mattoni in foglio in Sicilia (Intervention on tiled vaults in Sicily)

2016

Recenti studi hanno confermato come la diffusione nella Sicilia occidentale delle volte sottili di mattoni in foglio (“realine”) sia avvenuta in maniera estesa dalla seconda metà del secolo XVIII ai primi decenni del Novecento, sia negli orizzontamenti e nelle scale dell'edilizia corrente, che con funzione portante e di soffittatura nelle architetture nobiliari. Per finalità di studio o professionali se ne sono analizzati i caratteri costruttivi, le costanti e le variabili, con verifiche su strutture che hanno superato indenni le prove del tempo. In laboratorio o nei cantieri sono state effettuate sperimentazioni accademiche ed interventi di recupero, con ricostruzioni parziali o totali e i…

The Harvesting Memories Project: Landscape Archaeology in the Castro/Giardinello Valley and Mt. Barraù (Corleone, Palermo)

2018

Il progetto Harvesting Memories è finalizzato allo studio delle interazioni tra dinamiche umane e fattori ecologici che nella lunga durata hanno contribuito alla formazione dei paesaggi rurali. L’area di studio è localizzata tra Corleone e Campofiorito (Palermo) nei pressi delle contrade Castro e Giardinello e lungo le pendici occidentali di Monte Barrù. Questo distretto dell’Alto Belice Corleonese ha rappresentato un asse di collegamento tra la costa meridionale della Sicilia e quella settentrionale fin all’epoca repubblicana con continuità anche nel Medioevo in cui è citato per la prima volta il toponimo Barraù/Barracù, dal nome arabo ra’s e ǧabal bū ‘r-raḫū, nella Jarida di Monreale del …
