Sažetak
The mapping of the North Velebit region provided for the first time the evidence of glaciation traces. Three glaciation types have been determined: cirque, valley and plateau glaciation. The glaciation affected the top part of the mountain, above 1400 meters height. Therefore, the glaciation had regional properties. The following morphological forms have been positively found out and mapped: exara-tion forms (glacier valleys, cirques, aretes, striae and polished surfaces) and accumulation glacial morphological forms. Moraine forms (frontal, terminal, slope and end moraines) undoubtedly point out that the North Velebit glaciation occured two stages. There were three glaciation centres: in the Zavižan basin, Lubeno-vačko polje and on the Jezero plateau. From the basin »Lubenovačko polje« ice was flowing versus the Alan pass and in three parts versus the Bakovac valley and the »Veliki kotao« basin. A whole range of stadial, frontal and terminal moraines has been discovered. The longest one was the so called glacier of »Lomska duliba« over 10 km) which originated in the Zavižan basin. The terminal moraine was formed in Studena draga. A plateau-like glacier glided with one arm towards the Krasno polje basin and with another one through the Apatišanska duliba. For both arms, the corresponding frontal and terminal moraines have been discovered.
