The largest part of the eastern coast consists of carbonate rocks, while flysch (a particular type of sedimentary rock) is significantly represented in the Gulf of Trieste coast, especially along Slovenia's coast where the 80 meters Strunjan cliff—the highest cliff on the entire Adriatic and the only one of its type on the eastern Adriatic coast—is located, on the Kvarner Gulf coast opposite Krk, and in Dalmatia north of Split.
