The Croatian mountain chain Velebit is probably the richest area in karstic uvalas of the Dinarides, Poljak (1951) cited by Ćalić (2009) p. 70. The breccia in this chain - there known as Jelar breccia - show very extensive outcropping. These highly permeable carbonate breccias are a prominent feature of Middle Eocene to Middle Miocene age faulting activities in the Velebit area, Vlahovic et al. (2012). The deep incision of Velebit's most prominent uvala Lomska Duliba can be explained by the presence of the Jelar breccias, Ćalić (2009), p. 72.
