Geomorphological Traces of the Younger Pleistocene Glaciation in the Central Part of the Velebit Mt.

Abstract

On the central part of the Velebit Mountain the traces of the Pleistocene glaciation have been found. The domination of the dissected relief, characterized by numerous elevations and depressions, in the conditions of low temperatures and richess of snow precipitation during the Pleistocene were a very good predisposition for glaciation development on the central part of the Velebit Mt.Key words: moraines, Pleistocene, glacial valleys, cirques, plateau glaciers, Velebit Mt. Croatia Geomorfološki tragovi glacijacije u mlađem pleistocenu na Srednjem VelebituNa području Srednjeg Velebita utvrđeni su tragovi pleistocenske oledbe. Dominantna mrežasta struktura reljefa karakterizirana nizom uzvišenja i udubljenja u uvjetima niskih temperatura i bogatstva snježnih padalina tijekom pleistocena bili su iznimno povoljna predispozicja za razvoj oledbe na istraživanom području.

Krasno polje on Velebit Mountain: morphographic and morphogenetic characteristics

“…Those moraines had already been identified within earlier studies (Bognar et al, 1991a;Bognar et al, 1991b;Faivre, 1991). The moraines height is up to 80 m with length at about1.1 km.…”

“…Northern Velebit was intensively modified by glacial processes during the Pleistocene (Bognar et al, 1991a;Bognar et al, 1991b;Faivre, 1991). Current literature quotes that glaciers which occupied an area of about 115 km 2 were positioned at elevations higher than 1300 -1400 m. On the southern slopes above Krasno polje, three glacial cirques were identified: Žestikovac, Splitvina and Ripljevica (Bognar et al, 1991a;Bognar et al, 1991b;Faivre, 1991).…”

These cirques were supposedly functioning as heads for small scale cirque glaciers, which were between 750 to 1000 m long.…”

“…They were connected to the glacial plateau at Jezera only during the peaks of glaciation. The only two reported sites where glacial material was identified were below Ripljevica cirque in the area of Trapolovica and within Žestikovac valley (Bognar et al, 1991a;Bognar et al, 1991b;Faivre, 1991). Proglacial glaciofluvial accumulations, which consist of pebbly material, infilled parts of the Krasno polje floor (Bognar et al, 1991a;Bognar et al, 1991b;Faivre, 1991).…”

“…Na predjelu Trapolovica, oko 100 m iznad razine polja, nalazi se umjerena padina s većim pokrovom glacijalnog i proglacijalnog materijala koji je već identificiran u literaturi (Bognar i dr., 1991a(Bognar i dr., , 1991b. Od Trapolovice se niz (Bognar et al, 1991a;Bognar et al, 1991b). Downslope from Trapolovica is a gully entrenched into bedrock, which terminates on the southern slopes of the Veliko polje.…”
