Abstract

Field and biostratigraphic data from Cenozoic metasedimentary succession («breccia a selce», Colle Trodo and «Scisti del Fiume Lao» Formations) of Lungro-Verbicaro Unit are reported. The «Scisti del Fiume Lao» Formation, formerly included in the ophiolite-bearing Frido Unit, defined at the Calabria-Lucania border area, is interpreted as the stratigraphic uppermost part of the above Cenozoic succession. Therefore, the occurrence of nannofossil assemblage not older than late Aquitanian, represents the minimum age constrain both to the deformation and to the HP/LT metamorphic event affecting the Lungro-Verbicaro Unit. This age is in agreement with the Burdigalian radiometric age recognized in metavolcanic and metapelitic rocks of Lungro-Verbicaro Unit.
