Archaeometric evidence attesting production of indigenous archaic pottery at Monte Polizzo (Western Sicily)
2012
Excavations at the proto-urban indigenous settlement of Monte Polizzo (western Sicily) have not yielded so far any evidence of in-situ ceramic production (i.e. kiln structures). However several archaeological concerns put forward to consider it as a likely production centre of pottery during the Archaic age. In this paper a first attempt to check the compositional correspondence between ceramic fabrics and local clay sources has been made. A comprehensive archaeometric investigation of native pottery, mainly composed of matte-painted table ware dated from the 7th to the 4th century BC, recovered from the Acropolis of Monte Polizzo has allowed the identification of five distinct ‘Paste Compo…
Timbrel vaults in Sicily: analysis of a little-known construction technique
2016
La ricerca di alternative al legno per la realizzazione di orizzontamenti ha condotto ad approfondimenti e sperimentazioni sulle strutture voltate, con risultati di grande originalità in grado di coniugare economia e leggerezza senza perdere in sicurezza; vengono qui analizzate le volte siciliane costituite da più fogli di mattoni sottili uniti con gesso (volte realine secondo la definizione locale). Già ampiamente documentata nella Spagna tardo-medievale, la tecnica venne introdotta saltuariamente in Sicilia a partire dalla fine del XV secolo, ed assunse un ruolo importante dalla metà del XVIII. Attraverso l’analisi diretta e delle documentazioni relative ai maggiori cantieri e dai prezzia…
First record of Aplysia dactylomela (Opisthobranchia: Aplysiidae) from the Egadi Islands (western Sicily)
2014
The alien mollusc Aplysia dactylomela is recorded for the first time from the Egadi Islands marine protected area (western Sicily). This species has been widely reported in the Mediterranean and has established populations in Sicily. The presence of a few specimens let us suppose that its occurrence in this area is a recent event and that soon new populations will be sighted in the whole Egadi Islands and on the western and southern coasts of Sicily.

Deep structural setting of the Rocca Busambra Ridge (central-western Sicily): a seismostratigraphic reconstruction

L'incremento della sostenibilità ambientale attraverso una corretta gestione dell'irrigazione.
2014
Lo scopo di questo lavoro è quello di mettere a punto, a partire dalle informazioni territoriali quali caratteristichemeteorologiche e pedologiche, uno studio capace di valutare la sostenibilità della gestione irrigua in tre ipotetiche parcelle sperimentali individuate nel territorio del sottobacino Iudeo-Bucari (TP). Sitratta di tre vigneti che rappresentano per caratteristiche morfologiche e gestionali l'intero sottobacino, ovvero una delle aree maggiormente vitate della Sicilia. Il fine è valutare la sostenibilità della gestione irrigua in termini di risparmio energetico, attraverso l'applicazione del modello di bilancio idrico FAO 56. Questo tipo di studio pone le basi per la redazione …
Seismotectonics of the active thrust front in southwestern Sicily: hints on the Belice and Selinunte seismogenic sources
2014
We present a seismotectonic model of the active thrust front in western Sicily, which includes the area hit by the 1968 Belice earthquake sequence. The ~40 km long South-WEstern Sicilian Thrust (SWEST) is formed by two aligned albeit non-parallel fault arrays, the Granitola-Castelevetrano Thrust System (GCTS) in the west and the Partanna- Poggioreale Thrust System (PPTS) in the east. The ~NE-SW trending, NW-dipping GCTS straddles from the Pelagian coastline to Castelvetrano, is ~18 km long and composed of two segments, with the northern, ~12 km long one showing geodetic and geologic evidence of active deformation (Barreca et al., 2014). The segment is marked by a sharp gradient in Different…
Mesozoic tectonics and volcanism from Tethyan rifted continental margins in western Sicily
2009
Tectonic and volcanic features from the Jurassic-Cretaceous carbonate successions of Rocca Busambra, Balatelle Mount and Vicari-Roccapalumba (central-western Sicily), are here described. These areas represent the easternmost outcrops of the Trapanese domain in Sicily. The Trapanese succession consists of shallow to deep-water Meso-Cenozoic deposits formed in a carbonate platform to pelagic plateau depositional setting. Detailed field work and structural analysis detected indicate the occurrence of paleofaults with different orientation, unconformity surfaces, lateral facies changes, resedimented materials and volcanic products (pillow lavas and tuffitic deposits). These data combined with f…
Architecture and Pliocene to Recent evolution of the offshore prolongation of the Granitola - Castelvetrano Thrust System (Sicily Channel)
2014
High-resolution, seismic profiles were recorded in the offshore of Mazara - Punta Granitola with the purpose of reconstructing the architecture and Pliocene to Recent evolution of the south-west prolongation of the Granitola- Castelvetrano Thrust System, identified as an active structure possibly related to destructive historical earthquakes (Barreca et al., 2014; Ferranti et al., this meeting). A number of seismic units were identified. The oldest one is interpreted as representative of the Lower Pliocene pelagic deposits known in the region as Trubi. Lower-middle Pleistocene calcarenites are widespread along the continental shelf (CS) between Mazara del Vallo while their top rapidly deepe…
