En "flyttblokk" av finsand.
Abstract
An \"erratic boulder\" of fine sand: A special, isolated deposit of fine sand in a coarse sand deposit of fluvio-glacial character at Brusletten, Dovre, in central Norway has been described. The fine sand has probably been incorporated in the coarse sand deposit as a frozen mass. In order to gain a better understanding of the mode of formation of Norwegian fluvio-glacial deposits, it would seem necessary to lay greater weight in the study of the structures within the soil material itself.
