Pleistocenska poledenitev v Logarski dolini

Abstract

Članek prinaša rezultate preučevanja ledeniških ostankov iz časa zadnjega poledenitvenega viška na območju Logarske doline v Kamniško-Savinjskih Alpah. Namen članka je reinterpretirati dosedanje ugotovitve in podati novo tolmačenje obsega viška zadnje poledenitve na tem območju. S pomočjo ugotovitev, pridobljenih s terenskim delom, so bile opravljene morfometrične analize, po katerih smo začrtali skrajno mejo poledenitvenega sunka in izdelali tridimenzionalno rekonstrukcijo topografije površja takratnega ledenika.

The traces of the last pleistocene glacial maximum in the eastern Kamnik-Savinja Alps

“…Krofička, Škrbina, Ojstrica, Molička peč and others) or with alluvial deposits of the Bela Stream. The moraines in the Robanov kot Valley are at similar altitudes as the moraines in the Logar Valley, where they are at approximately 1004 m (Stojilković, Stepišnik, Žebre, 2013). This indicates that the glaciers shared similar ELA characteristic and that the palaeo-microclimatic conditions affected the two glaciers in the same way.…”

“…All the geomorphological evidence in the Logar Valley, presented in the previous literature, was re-checked by Stojilković, Stepišnik and Žebre (2013), who concluded that there were two glaciers in the area: the smaller one in the Klemenča jama Valley and the main glacier in the Logar Valley itself. The latter stretched from 1945 m to 860 m above the sea level, which is considerably less than it had been estimated before.…”

“…There are several larger blocks at the end of the Logar Valley, which Meze (1966) attributed to the Matkov kot glacier. The stones are of the same structure as surrounding slope on the eastern side of the valley, which makes them dropstones, rather than glacial boulders (Stojilković, Stepišnik, Žebre, 2013). Lucerna (1906) and Meze (1966) mapped the extent of the glacier in the Logar Valley similarly.…”

“…The Logar Valley glacier ended at the terminal moraine on the elevation of 860 m above the sea level. The glacier in the Klemenča jama Valley stretched between the altitudes of 1880 and 1135 m (Stojilković, Stepišnik, Žebre, 2013). The glacial remains in the study made by Stojilković, Stepišnik and Žebre (2013) were re-examined once again, but no further changes were made to the glacial-geomorphological map of the area.…”
