Description:
A diffuse fragmentation of the Nubia-Eurasia tectonic
boundary, due to the propagation of distinct extensional belts,
has characterised the post-collision evolution of the region. In
this frame, the Hyblean Plateau was affected, since about 1.5
Ma B.P., by the propagation of the the roughly N-S trending
Siculo-Calabrian Rift Zone (SCRZ in Fig.1a; MONACO &
TORTORICI, 2000), an extensional belt that extends from the
onshore of southern Calabria to the SE Sicily. In the Hyblean
plateau the propagation of the rift zone caused the reactivation
of the main previous discontinuity. The earlier SE Sicily
branch of the rift zone, in fact, propagated from the Ionian
coast to the Scicli Line, causing the collapse of the NEtrending
Scordia-Lentini Graben, at the northern margin of the
plateau. This extensional basin represents an half-graben,
which is controlled by a SE-facing master fault.
