“…In fact, palaeomagnetic data from Sicily indicate that large CW rotation affected the Mesozoic to Pliocene sediments stacked within the fold-and-thrust belt (Channell et al 1990;Speranza et al 1999Speranza et al , 2003. A CW rotation of about 708 occurred between Langhian and Late Tortonian, whereas 308 CW rotation affected the thrust-and-fold belt between Messinian and early Pleistocene.…”

The evolution of the southern Tyrrhenian subduction has been possibly controlled by distinct episodes of slab break-off as indicated by a critical review of the geological literature and by the analysis of purposely acquired multichannel seismic profiles. Within the proposed interpretation the first episode occurred from 8.5 to 4.0 Ma and affected the segment of the slab located in the Sardinia Channel, causing the abandonment of the Adventure thrust front in western Sicily. The second episode occurred between 2.5 and 1.6 Ma, affecting the segment of slab located north of Sicily, and was preceeded by rifting in the Strait of Sicily. The space and time location of these episodes appear controlled by discontinuities pre-existing within the subducted African plate that trend at high angle to the advancing subduction front. These discontinuities delimit segment of subducted slab that can be affected by slab break-off and can act as wayouts for magma and mantle derived He. The major of these discontinuities, the Malta Escarpment, has been reactivated in the Quaternary as a trench-perpendicular tear (STEP faults). Ultimately, the hierarchy in strength of these trench-perpendicular features could have affected the timing and amount of trench retreat and backarc opening.

“…Thrust sheets propagation was also accompanied by large clockwise rotations, as documented by paleomagnetic data (Channell, Catalano, & Argenio, 1980;Channell, Oldow, Catalano, & Argenio, 1990;Grasso, Manzoni, & Quintili, 1987;Speranza et al, 1999;Speranza, Maniscalco, & Grasso, 2003) and corroborated by structural analysis in central (Barreca & Monaco, 2009, 2013 and eastern Sicily (Monaco & De Guidi, 2006). The last stage of deformation is Figure 1.…”

Geological and structural surveys were undertaken in central-northern Sicily along the southern slope of the Madonie Mts., a portion of the Sicilian Fold and Thrust Belt. Collected data have allowed the compilation of a new map of this region at 1:30,000 scale. The map is the result of a classic field survey supported by a combined analysis of 1:33,000 aerial photographs, 1:10,000 ortho-photos, and the use of a high-resolution Digital Elevation Model.The cartographic product displays the distribution of the distinct sedimentary successions and the geometric setting of the major tectonic lineaments, providing further constraints on the geology of the area. The mapped rocks mostly consist of Neogene syn-tectonic sedimentary successions deposited within basins developed in a SE-migrating piggy-back/foredeep system. Thrust-top deposits are floored by a clayey substratum pertaining to a former oceanic domain.The tectonic setting has been reconstructed through the mapping of structural lineaments and compared to available seismic sections. The geometries and orientation of the observed/ measured faults and folds and the age of the sediments involved, suggest that since Miocene times the area experienced a multi-phased deformation with previously formed (middle Miocene) large flat thrusts and associated folds, re-deformed by a younger (Upper Miocene to Early Pliocene) and deep-seated thrust and folds system. Strike-slip deformation affected the area after the Early Pliocene with the nucleation of NW-SE-oriented right-lateral faults whose propagation produced vertical axis rotations with a general re-orientation of previously formed structures.
