EVOLUZIONE STRUTTURALE DEI BACINI NEOGENICI ESTENSIONALI SOVRAIMPOSTI ALL'OROGENE MAGHREBIDE NEI DINTORNI DELLE ISOLE EGADI

Abstract

Extensional basins are known to occur on top of the Apennine-Maghrebian fold and thrust belt that runs along Sicily and peninsular Italy. They formed mainly during the Plio-Quaternary, presumably in relation to the opening of the Tyrrhenian back-arc basin, while contraction was active at the thrust front and contractional structures are often present within their sedimentary fill. Two of these basins, named INVOl and INVO2 are located in the NW side of the Strait of Sicily and have been investigated, using a grid of multichannel seismic reflection profiles, in order to define their structural style.
