Summary
The superficial deposits within the area of map-sheet Reisadalen, 1734 III, in nothern Troms, North Norway, are classified according to their genesis and described. Ice movements and the course of deglaciation are reconstructed. The Reisafjord moraines are correlated with the Tromsø-Lyngen or the Ra moraines of Younger Dryas age. The younger Storbakken, Bergmo and Sappen moraines are of Preboral age, formed 9900-9800 B.P., 9700-9500 B.P. and 9400±250 B.P., respectively. Short accounts are given on shorelines, shore-level displacement and pollen analyses. Till and weathering material cover large areas of the mountainous regions. The bottom of the valley is filled with loose deposits with thicknesses up to 200 m. Large deposits of glaciofluvial and fluvial material represent valuable sand and gravel resources in the area. The potential for different utiliziation of the superficial deposits is also briefly discussed.
