Description :
Recent studies of littoral geomorphology in Sardinia have showed the existence of numerous beach-rock outcrops. These can be classified into two generations: the first one which goes up to 50 cm, whose emerged part is often corroded and whose immerged part is broken into polygonal paving-flags. The second lays on the tidal zone and sometimes contains Roman or Punic artefacts. On the other hand, different oceanographic missions and diving operations have discovered several beach-rocks spread over the continental shelf down to a depth of 100 m. They give evidence of contemporaneous shorelines with the Versilian transgression.
