The age of the Paludi Formation: a major constraint to the beginning of the Apulia‐verging orogenic transport in the northern sector of the Calabria–Peloritani Arc

Abstract

AbstractA stratigraphic revision of the Paludi Formation, cropping out in Northern Calabria on the north‐eastern side of Sila Massif, has confirmed that it has been deposited between two main tectonic phases. Actually the formation is involved only by top to the north‐east thrusts, different from those separating the crystalline and ophiolitic nappes of Northern Calabria, and rests unconformably on the Sila Unit, the uppermost nappe of the tectonic stack. In the frame of the interpretation of Northern Calabria as a fragment of the Alps, the Paludi Formation play the role of a deposit post‐dating the eo‐alpine tectonic phases and pre‐dating the Apenninic orogenic transport. Therefore the Aquitanian age of the formation, obtained by nannofloras analyses, can be considered the minimum age to the Apulia‐verging orogenic transport, witnessed by top to north‐east thrusts. It fairly corresponds to the age referred to the Lucanian ocean closure.
