description

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 images also that high angle faults affected the Trapanese Unit (TP) locally producing a back-verging younger structural high. The tectonic strain associated to high angle faults, within the TP units, is transferred along the oldest thrust plane to the upper structural layers moving northward to the innermost sectors.
