Late-Glacial Accumulations, Drainage and Ice Recession in the Narvik-Skjomen District, Norway

Abstract

Dahl, R. 1968. Late-Glacial Accumulations, Drainage and Ice Recession in the Narvik-Skjomen District, Norway. Norsk geogr. Tidsskr. 22, 101–165 Late-glacial accumulations in the Narvik-Skjomen and Tysfjord districts are described and discussed, in order to illustrate the course of deglaciation after the Tromsö-Lyngen sub-stage. Most of the late-glacial accumulations at low levels in these districts are ice-front deltas or delta moraines. Thus they cannot be correlated with the drainage of any large ice-dammed lakes E of the watershed, as has earlier been maintained. Repeated beds of moraine on stratified sediments show that there were small climatic fluctuations even when the ice-fronts were situated in the inner parts of the fjord valleys. But the different accumulations are not synchronous. They are all situated where the topographical conditions diminished the effect of calving. The ages of the investigated ice-front accumulations have been calculated on the basis of shorelines and some C¹⁴-datings. According to these calculations the heads of the fjord valleys were deglaciated at low levels as early as 7900–7500 years B.C.
