Geomorphological Characteristics of Dugi Otok Island, Croatia

Dugi otok je najveći (114 km2) i najduži otok (44,4 km) zadarskog arhipelaga. Prema razvedenosti obalne crte (4,5) drugi je na Jadranu. Glavne geomorfološke karakteristike otoka su relativno velika podudarnost orografije s temeljnim geološkim strukturama i prevlast krškog tipa reljefa na karbonatnoj litološkoj osnovi. Bitan je i marinski tip reljefa, odnosno abrazijski proces. Usporednost otoka s temeljnim reljefnim i geološkim strukturama susjednog kopna svrstava otok u tip kontinentskih otoka izduženih dinarskim pravcem pružanja SZ-JI. Današnje reljefne značajke su posljedica poslijepleistocenske ingresije mora kada se svjetska morska razina izdigla oko 100 m.Dugi Otok Island is the biggest (114 km2) and the longest (44.4 km) of all Zadar archipelago islands. According to the coast indentedness (4.5), it is the second island in the Adriatic Sea. Basic geomorphological characteristics of the island are relatively great concordance of orography and basic geological structure and predominance of the karstic type of relief on the carbonate lithological basis. Marine type of relief is very characteristic, especially the features formed by abrasion process. Parallelism of the island with relief and geological structures of neighbouring mainland classifies the island into the type of continental islands extended in Dinaric NW-SE direction. Today\u27s relief characteristics are primarily the result of the post-Pleistocene sea ingresion, which is the consequence of the general raising of the world sea level for ca. 100 m
