摘要
The present paper has two aims: first, to re-evaluate the rotation of the Hyblean Plateau with respect to Africa in the light of updated African paleopoles; second, to obtain information about the block rotation pattern, possibly associated with the Scicli-Ragusa strike-slip fault zone. Our results complement pre-existing data and firmly indicate that: 1) the Hyblean Plateau did not rotate with respect to Africa, even during the Pliocene-Pleistocene rifting of the Strait of Sicily; 2) the Scicli-Ragusa fault system did not induce significant block rotations around vertical axis and therefore, the horizontal displacement of this tectonic lineament has to be considered less than 3 km.
