Varaiety of coralline algal deposits (rhodalgal facies) from the Bays of Naples and Pozzuoli (northern Tyrrenian Sea, Italy).

The Bays of Naples and Pozzuoli are extremely influenced by their geological and tectonic history, which has had a strong influence on the features and morphology of the sea bottom. The occurrence and variability of the coralline algal (rhodalgal) facies both in active factories and in palimpsest and/or winnowed deposits in the Bay of Naples and the Bay of Pozzuoli is reported in this paper. The present-day coralline algal deposits resulted from the complex volcano-tectonic events and biological changes which occurred in the Phlegrean Fields, in particular after the sea-level lowstand at the last glacial maximum regression and the succeeding Holocene transgression.
