Sažetak
The Upper Palaeozoic tectonic belt of the Mt. Velebit and Lika region represents the best known and most completely developed Palaeozoic area in Croatia. Sediments exposed here range from the Pennsylvanian (Moscovian) to the Late Permian in age. Carbonate sedimentation took part sporadically during the Carboniferous and Early Permian. Intensive tectonic uplift at the beginning of the Middle Permian caused the formation of prominent relief and its rapid erosion, followed by sedimentation of terrigenous molasse sediments. The reef evolution can be summarized in 7 phases: 1) substrate colonization ; 2) the formation of primary reef framework with dwellers ; 3) reef framework encrustation ; 4) early lithification ; 5) shallowing (relative sea-level fall), followed by weathering and erosion ; 6) infilling of secondary reef porosity ; 7) deepening (reletive sea-level rise), followed by recolonization (or final burial as after reef body C) The Palaeozoic sediments of the Velebit Mt. can be considered as a foundation of the later carbonate platform environment, subsequently developed, here and elsewhere in the External Dinarides in the course of Mesozoic time.
