Název v původním jazyce

Sedimentary petrological characteristics of lateral and frontal moraine and proglacial glaciofluvial sediments of Bertilbreen, Central Svalbard

Popis výsledku v původním jazyce

Clast petrology, shape, roundness and striation were studied in various types of glacial deposits of Bertilbreen in central Svalbard. Difference between the upper part of lateral moraine and the lower part of lateral and frontal moraine (latero-frontal zone near the ice margin) was determined. The upper part of lateral moraine contains mostly very angular to subangular clasts of blade and icometric shapes without striation traces. Clasts in lower part of lateral moraine and in frontal moraine are mostlysubangular and subrounded with isometric shapes. 30?50% of these clasts are striated. Types of source sediments and available bedrock outcrops affect the nature of proglacial glaciolfuvial braidstream sediments. Clast surface striation is preserved. A braided outwash fan formed in the distal part of the braidstream. The clast nature here is affected by the dynamic of the glaciofluvial transport, thus subrounded clasts predominates. Striation is not preserved on clast surfaces here.
