The relict (palimpsest and lowstand) deposits of the Cilento continental shelf have been analyzed based on the geological interpretation of subsurface Chirp sections, calibrated with core data. A progradational unit, overlying the acoustic basement, is interpreted as the beach deposits of the isotopic stages 4 and 5. This unit is overlain by a seismo-stratigraphic unit, composed of coarse-grained organogenic sands and interpreted as relict sands. This unit consists of sandy ridges, occurring at water depths ranging between 130 and 140 m and has been interpreted as submerged beach deposits, genetically related with the marine isotopic stage 2 (Last Glacial Maximum; starting date 29 ky B.P.) .
