Sažetak
The present erosional surfaces on the Dinarides can be found at various levels (South-Istrian, North-Dalmatian, Zadvarska, Brotnjo-Dubrava, Lika’s, the erosional surface on Northern Velebit, on the mountain massifs of Èvrsnica, Bjelašnica, Treskavica, Durmitor, etc:) ; consequently, nearly from sea level to 1, 000 m and more than 2, 000 m above sea-level, they represent traces of one, once larger, complete, and older planation surface. During the neotectonic development stage, this surface was intensively disarranged and fragmented, and its surviving sections were transported to various hypsometric positions. Some evidence for this model can be deduced by the observation of regionally extensive bauxites, which can be treated as correlative weathering sediments in tropic-equatorial climatic conditions. The existence for such climatic regime has never been proposed for the Cainozoic ; consequently, this model describes a unique peneplained planated surface of the Mesozoic age. Erosional surfaces can be observed on the majority of the mountain ranges and massifs of folded-thrust and folded-imbricated structuralgenetic material in the Outer Dinarides mountain zone. These are characterised by a specific step-like outline of their transversal profiles. This scenario supports their complex geomorphologic evolution marked by the alternation of uplift stages with those of relative tectonic inactivity favourable to denudational-planation processes, relations proved by the existence of two clearly marked steps-pediments. Ecpections are the fragments of older erosional levels, i. e. the surface, which are, in view of their morphologic position, connected with the mountain ranges’ tops and massifs, then with the parts of the poljes in karst bottoms, the marginal parts of the Outer Dinarides towards the Adriatic basin, and with the Pannonian basisn.
