Deducing large scale-listric normel faults geometries from analysis of minor structures

A contribution to a seismotectonic model of the hinge zone between northern Sicily and southern Tyrrhenian by some seismological and structural const…
2013
An integrated research on the hinge zone between northern Sicily and its Tyrrhenian off-shore has been carried out, by means of structural, seismological and statistical analyses. The main structural features of the area are represented by both NWSE to W–E striking right-lateral and N–S to NE-SW striking leftlateral fault systems, responsible of uplifting (restraining) and subsiding (releasing) zones. Within this hinge zone the seismicity is mainly located between 10 and 20 km of depth and clustered according to the orientation of the outcropping fault systems. The brittle strain partitioning related to a right-lateral simple shear zone has been reconstructed in the onshore sector, while in…
3D structural modeling and restoration in fold-and-thrust belts: examples from the Kumeta and Busambra Mts., NW Sicily (Italy)
2018
The Sicilian Fold and Thrust belt (SFTB) is a structurally complex area where along-strike variations of structural styles, shortening amounts, exhumation rates and amounts of syn-tectonic sedimentation frequently occur. Moreover strong differential clockwise rotations around vertical axes affected the different tectonic units during their emplacement. This complexity, coupled with debatable or incomplete subsurface dataset (e.g., available 2D onshore seismic lines) allowed previous authors to propose different interpretations for the tectonic evolution of the SFTB since Cenozoic time. The study area, located in the Western sector of the SFTB comprises the Kumeta and Busambra ridges (derive…
