The Gorgoglione Flysch within the scope of the evolution of the Lucanian Apennines

The Gorgoglione Flysch has been examined in the Basin of the Agri River where new stratigraphical and structural data have been collected. Sedimentologically, the Gorgoglione Flysch was deposited inside satellite basins of the mobile Apenninic belt connected with Middle-Upper Miocene foredeep deposits (External Flysch) which probably were deposited upon the internalmost collapsed Apulian carbonate sequences. The Gorgoglione Flysch represents the evolution through time of the earlier Albidona Flysch which was deposited within more internal Lower Miocene satellite basins. The Gorgoglione Flysch is relatively undeformed thus the geometries of the structures which have been sealed by the Flysch are still well preserved. Early structures originated during the migration of the Apenninic chain-foredeep-foreland system during the Lower Miocene when large decollement processes of the foredeep deposits occurred. The later structures are related to "out of sequences' thrust deformations. The Gorgoglione Flysch can be interpreted as deposited within an "episutural' basin, heralding the end of the propagation of the Apenninic thrust system and the onset of the later overthrust of Apenninic Chain upon the Apulian Platform carbonate sequences and to the thrust deformation which gave rise to the buried Apulian Chain. -from English summary
