An extensive apatite fission‐track survey has been carried out on the Marnoso‐arenacea foredeep succession in the Northern Apennines. The data show a general decrease of the maximum paleotemperature undergone by the sediments toward the foreland areas. The maximum burial calculated by using a geothermal gradient of 20°C km−1 spans from more than 5 km to less than 2.5 km and indicates that the previously assessed total thickness of the Marnoso‐arenacea succession is not enough to justify the determined values. It is concluded that a now eroded Ligurian wedge, up to 5 km thick, was present on top of the Marnoso‐arenacea sediments.
