Dugi Otok (Croatian for "Long Island, Isola Lunga in Italian), the seventh-largest island in the Adriatic Sea and the westernmost of the Zadarian Islands, derives its name from the distinctive elongated shape. It is a part of the Adriatic carbonate platform and belongs to the Dinaridic orogenic mountain chain.

The island consists entirely of gastropod-bearing fossiliferous Upper Cretaceous limestone and minor dolostone showing various karstification phenomena (Džaja, 2003).

A manganese mineralisation, consisting of predominant todorokite, accessory MnO·OH and very minor quartz and illite, occurs and is restricted to the Upper Cretaceous carbonates of the SW backshore zone of the island and adjacent submarine terraces of bedding carbonate. It appears as fine-laminated films, crusts or small concretions onto the bedding planes of the host carbonate rocks, whereby spatially adjacent goethite mineralisation may be also coated by manganese crusts.
