Abstract

Pleistocen pripada periodu Kvartar i trajao je oko 2,5 milijuna godina. Za vrijeme Pleistocena zabilježena su četiri razdoblja glacijala i četiri razdoblja interglacijala. Dva su recentna primjera ledenih pokrova koja su postojala i tijekom pleistocenskih glacijacija, jedan prekriva Grenland, a drugi Antarktik. Glacijalno taloženje na Velebitu potvrđeno je iz analiziranja jezerskih ostrakoda. Između najviših vrhova Velebita nalaze se krške depresije koje su se nekad ponašale kao ledenjačke doline. Glacijacije na Velebitu i Biokovu potvrđuju brojni nalazi eratičkih blokova, drumlina, eskera i morena. Na području Snežnika dobro su očuvani glacijalne naslage pa takav krajolik nazivamo glaciokrš. Dokaza o glacijacijama Gorskog kotara nema mnogo, ali morene na njegovoj južnoj strani nam ukazuju na postojanje i na smjer kretanja ledenjaka. Najčešće metode korištene za datiranje oblikovanja glacijalnih reljefa su metoda terestičkih kozmogenih nuklida i PISM.

Abstract (english)

The Pleistocene belongs to the Quaternary period and lasted about 2.5 million years. During the Pleistocene, four glacial periods and four interglacial periods were recorded. There are two recent examples of ice sheets that existed during the Pleistocene glaciations, one covering Greenland and the other Antarctica. Glacial deposition on Velebit was confirmed by analysing lake ostracods. Between the highest peaks of Velebit are karst depressions that once behaved like glacial valleys. Glaciations on Velebit and Biokovo are confirmed by numerous finds of erratic blocks, drumlins, eskers and moraines. In the area of Snežnik, glacial deposits are well preserved, so we call such a landscape glaciokarst. There is not much evidence of the glaciations of Gorski kotar, but the moraines on its southern side indicate the existence and direction of glacier movement. The most common methods used to date the formation of glacial reliefs are the method of terrestrial cosmogenic nuclides and PISM.
