ATTI E MEMORIE DELLA COMMISSIONE GROTTE EUGENIO BOEGAN
Abstract
The NW coast of the Gulf of Trieste (GOT) is cut in carbonate rocks which overthrust the Eocene turbiditic succession. The coastal setting is strongly influenced by the structural setting of the GOT. In this paper, the coastal landscape of the NW sector of the GOT, which represents the northernmost boundary of the dalmatic coasts, is discussed. The study area is dominated by high limestone plunging cliffs, with a depth at the toe ranging from 1 m to 7 m b.s.l. at Duino. The northernwesternmost part is dominated by the Timavo springs. Along the coast, the submarine springs can be easily located during dry periods thanks to the significant in temperature and electrical conductivity between fresh- and salt-water. The occurrence of submerged forms related to the tides, such as marine notches and marine terraces testifies the late Holocene tectonic subsidence of the area.
