Abstract

Sediment types and depositional environments are correlatable in the Strait of Sicily: coarse calcareous sand layers, interbedded with mud and sandy lutite (fining- and coarsening-upward sequences), prevail on shallow banks; homogeneous mud occurs in the neritic and bathyal environments and also in some basins; and moderate- to well-stratified units (sandy gravity-flow deposits alternating with hemipelagic and turbiditic mud) increase as hemipelagic mud decreases with increasing depth. Bioturbation also is closely depth related. This type of lithofacies determination is a potentially useful technique to interpret the depositional environment of marine sequences in the rock record.
