Geomorphology of submerged late Quaternary shorelines on the south Sardinian continental shelf

In the Gulf of Cagliari, S Sardinia, the following submerged morphologies are present: marine abrasion platform on the Miocene calcareous bedrock, conglomerates and beach sandstone cemented in an intertidal environment, and backshore depressions infilled with fine sediments. The beach rocks at -40 to -60m are attributed to the Holocene transgression on the basis of a detailed geomorphological study. At the same depth the mottling of the abrasion platform by karstic dissolution probably occurred during the last glacial regression.-from Authors
