Summary
The superficial deposits within the area of the map-sheet Askvoll, in western Norway are classified and described. Ice movements and the course of deglaciation are reconstructed. The thin and discontinous cover of till and the weathering material are the most extensive deposits in the area. The bogs and the marine deposits are of some economic importance, being used for cultivation. Two glaciation phases are reconstructed on the basis of glacial striae. Ice movement during the older phase was towards the west; this must have been of the pre-Younger Dryas age. The younger phase corresponds well with the Younger Dryas end moraines. Grain-size and lithological analyses have been carried out on the superficial deposits. The tills are dominated by material from the local bedrock, and their predominant grain sizes are those of sand and gravel. Geochemical analyses have also been carried out on superficial deposits.
