Abstract The present paper aims to show, both from a stratigraphic and structural points of view, the main features of a wedge-top syntectonic basin which evolved recording polyphase and non-coaxial tectonics. The study area is the Scillato Basin ( SB ), a roughly N–S-oriented structural depression located in the central-northern sector of the Sicililian Maghrebides. There, an approximately 1300 m-thick upper Serravallian to upper Tortonian succession of clastic units outcrops as a portion of the Neogene syntectonic covers of the Sicilian fold and thrust belt. Within the outcropping succession the upper Tortonian Terravecchia Fm represents the main topic of this paper. A multidisciplinary a…

The “Camporeale Ridge” (NW Sicily): structural significance within deep-seated tectonics. The “Camporeale Ridge” is a morphostructural element cropping out in NW Sicily. Detailed structural and stratigraphic analysis carried out in the study area allows us to reconstruct a main E-W-trending anticline partially exposed along the ridge. Its development is due to the action of high-angle transpressive faults which bound both northwards and southwards site of the ridge. Seismic reflection profile crossing the study area images a tectonic stack made up of carbonates rocks (Trapanese Units, TP) overlain a numidian flysch and Neogene terrigenous units along a low angle thrust plane. The profile im…
