Il progetto CARG in Basilicata: il Foglio 489 Marsico Nuovo

The stratigraphic and structural features of the Apenninic Chain exposed in the Marsico Nuovo sheet are shortly described. The Apenninic edifice is composed of tectonic units, originated since Oligocene time. It is completely detached and resting onto a deep seated thrust system (the Apulian thrust system), deformed since Tortonian in contemporaneous with the Tyrrhenian opening. The geodynamic evolution of this latter influenced the further movements of the Apenninic Chain. Stratigraphic characters of the sequences outcropping in the studied area are here discussed. The deepest units are the Lagonegrese Mesozoic basinal sequences; these underlie the coeval carbonate platform units. A general decoupling between the Mesozoic sequences and the Tertiary flysch-type terrigenous covers occurs. Oil field traps have been dected in the ramp-anticlines of the buried thrust system and a lots of subsurface data allows to restore the whole geodynamic evolution of this area
