Pleistocene strike-slip tectonics in the Pollino Mountain Range (southern Italy)

In this area the Apennines belt is characterized by two main structural horizons, composed of a multilayer allochthonous complex (Liguride Complex) and of a rigid substratum given by a carbonate unit. The different rheology of the involved structural horizons controlled geometries and deformation style of the structures developing along the wrench zone. Two different patterns have been recognized prevalently affecting the carbonate unit (lower horizon structures) and the allochthonous terranes (upper horizon structures). In the studied area strike-slip tectonics were active in the Middle Pleistocene, induced by the last stages of the collisional processes occurring between the Apulian Block and the Apennines domain. Successively, strike-slip structures have been locally reactivated by still active extensional tectonics with T axes normal to the structural trend of the chain. -from Author
