Bijdrage tot de kennis van loess en dekzanden : in het bijzonder van de Zuidoostelijke Veluwe

A detailed map of loess and cover sand, occurring along the south-eastern border of the Veluwe; Gelderland, was made to check hypotheses on the origin of loess and cover sand.The eastern flank of the Veluwe hills, consisting of glacial sand and gravel, proved to be covered by fine cover sand near the summit, loess lower down and fine sandy colluvium at the bottom. This colluvium partly covers the fluvial deposits of the River Yssel.Many samples from the deposits in this area, from surrounding countries, and Greenland and Iceland were analysed for heavy mineral and grain size.The relation was determined between the geomorphology of the area, the position of the samples and the mineral and granular compositions.The importance of these studies for soil survey was stressed.The origin and deposition of loess and cover sands were described extensively.<p/
