Large-scale structural pattern as the result of the interplay between compression and extension during chain building: the case of the Sicily belt (central Mediterranean)

Molecular and isotopic composition of free hydrocarbon gases from Sicily, Italy

Chemical and isotopic data have been used as geochemical tracers for a genetic characterization of hydrocarbon gases from a total of eleven manifestations located in Eastern and Central-Southern Sicily (Italy). The molecular analysis shows that almost all the samples are enriched in methane (up to 93.2% Vol.), with the exception of four gas samples collected around Mt. Etna showing high mantle-derived CO2 content. Methane isotope signatures suggest that these are thermogenic gases or a mixture between thermogenic gases and microbial gases. Although samples from some mud volcanoes in Southern Sicily (Macalube di Aragona) show isotope signatures consistent with a mixing model between thermoge…

MODELLO IDROGEOLOGICO DEL CORPO IDRICO “FIUMARA DI CARONIA” (SICILIA SETTENTRIONALE)

L’Osservatorio delle acque del Dipartimento dell’Acqua e dei Rifiuti (DAR) della Regione Siciliana e l’Istituto Nazionale di Geofisica e Vulcanologia - Sezione di Palermo hanno attivato un accordo di collaborazione che prevede l’effettuazione di attività finalizzate alla redazione del “Piano di gestione delle Acque” della Regione Siciliana per numerosi bacini idrogeologici del territorio siciliano attraverso la definizione di modelli concettuali da sviluppare, previo approfondimento del quadro conoscitivo esistente, con l’effettuazione di indagini geologiche, idrogeologiche, geofisiche, idrogeochimiche ed isotopiche. In questo contesto, è stato analizzato il corpo idrico sotterraneo della f…

A regional-scale discontinuity in western Sicily revealed by a multidisciplinary approach: A new piece for understanding the geodynamic puzzle of the southern Mediterranean

The results of an integrated stratigraphic, structural, geophysical, and geochemical study reveal the presence of a crustal discontinuity in western Sicily that, at present, runs roughly N-S along a band from San Vito Lo Capo to Sciacca. The boundary between the two zones of this discontinuity is nearly orthogonal to the main thrust propagation of the Sicilian thrust-and-fold belt. The different Permian to Tertiary sedimentary evolution recorded by the two zones appears related to this discontinuity, with thick carbonate platforms in the western sector facing deepwater successions in the eastern one. The presence of Upper Triassic reefs, huge megabreccia bodies, and widespread submarine vol…
