Abstract
DAHL, RAGNAR. Late-glacial accumulation forms and glaciation in the Narvik-Skjomen district, Norway. Norsk geogr. Tidsskr. 1967, 21, 157–241. Late-glacial accumulation forms at corresponding levels are described and discussed. Most of the accumulations are moraine ridges deposited at the lateral margins of the ice flowing in the main valleys or at the lateral and frontal margins of ice tongues branching out into tributaries. The frontal moraine ridges appear only in small tributary valleys or similar depressions in the terrain. They have an arched form and an advanced position in the depressions and are broken by melt-water channels. Together with the different indications of pressure in the material, this shows that the moraines correspond to phases of the deglaciation period in which the ice masses were temporarily advancing. The calculated gradients of the ice surface and radio-carbon datings indicate that these phases correspond to the two glacial phases of the Tromsø-Lyngen substage, which, according to ANDERSEN (1965), approximately correspond to the Early Dryas and Late Dryas periods.
