Summary

The relationship between saprolite remnants and palaeosurfaces in Scandinavia is examined. Thin kaolinitic saprolites are associated with the sub-Cambrian peneplain and its contact with the Cambrian cover, whereas thick kaolinitic saprolites are associated with Mesozoic cover sediments and exhumed sub-Mesozoic (sub-Jurassic and sub-Cretaceous) undulating hilly relief. Characteristics of clayey–sandy and gravelly saprolites from several sites are described. Furthermore, mineralogical and chemical analyses of Weichselian deposits show that pre-weathered constituents may make up a substantial fraction of these deposits. Altogether this shows that deep weathering has been an important process in the shaping of relief even within formerly glaciated basement areas.
