Sažetak
Located along the Adriatic coast, the Velebit Mt. is the largest mountain range in Croatia. As a part of extensive Dinaric karst region, it consists of a wide variety of stratigraphic units, ranging in age from Carboniferous to Quaternary. Structurally, Velebit Mt. represents an anticline built up predominantly of carbonate rocks. The best developed karst features occur in the Jelar-breccia unit. Intensely tectonic deformed Jelar-breccia represents development of Paleogene deposits in the Karst Dinarides. These massive or thick- bedded carbonate breccias are built mostly from square, poorly sorted carbonate clasts of various sizes. Matrix is carbonate, gray to reddish coloured, whereas stratigraphic composition and size of clasts varies. Due to highly complex composition and differences in the composition of clasts (in relation to matrix) selective corrosion of these deposits occurs. Selective corrosion is further increased by micro-tectonic cracks in Jelar- breccia, as a result of intense tectonic deformations after sedimentation. All of these properties lead to increased weathering of rock mass, which results in “unusual relief forms“ development. From the sea-level up to the mountain top various types of karst relief forms occur: furrow-like karren (locally called žlibe), fissure karren (locally called škrape), rinnenkarren or runnels (solution grooves), network karren, debrits karren (locally called grohot), meandering karren, kamenitzas (solution pans), karst wells, natural bridges (locally called prozorci), and biocorrosion pits.
