Abstract

A 9 km long transect in the Gulf of Trieste, extending from the coastal cliff in the E across the Bay of Panzano into the Isonzo delta in the W, was investigated. Four sediment facies types were distinguished visually: sublittoral sand, sublittoral mud, delta foreset beds, and delta top depositions. The sediments were analysed with respect of grain size, carbonate content, as well as qualitative and quantitative composition of the sieve-fractions >250 μm. Considering all data, 4 integrated facies can be distinguished on the basis of cluster analysis: a terrigenous biogenic facies, a bivalve-ophiurid facies, a terrigenous plant facies, and a terrigenous rock fragment facies. The distribution of terrigenous sediments is mainly controlled by the Isonzo, coastal cliff erosion being restricted to a narrow strip along the coast. The carbonate content is controlled by the distribution of carbonate rock fragments and therefore also mainly by the input of the Isonzo -from Authors
