Summary
The superficial deposits occurring within the map-sheet area are classified according to their genesis and described. Till is the dominating sediment, but considerable glacifluvial deposits also occur. Glacier movement directions have been reconstructed in seven phases and subphases. The two youngest subphases correlate with events during the deglaciation. The older phases are considered to span most of Weichselian time. Of the eight glacial events known from the Porsangerfjord area, three occur within the map-area: The Outer Porsanger, Korsnes and Repparfjord events, with estimated ages about 13,500 - 11,500 years B.P. A broad marginal zone was produced during the Outer Porsanger event, extensive glacifluvial deposits are related to the Repparfjord event. Radiocarbon datings are lacking, suggested ages are based on correlation with dated events elsewhere.
