Continued investigations of Quaternary deposits in the area bounded by Søndre Strømfjord, the Inland Ice, and the Sukkertoppen Ice Cap

Abstract

The 1970 project was a continuation of more general 1969 investigations, some results and the objectives of which were reported by Weidick & Ten Brink (1969). The objectives of 1970 field work were to: (1) accurately determine altitudes and characteristics of marine limits; (2) complete a collection of marine shells and organic material from emerged marine deposits in order to derive a radiocarbon-dated delevelling history; (3) obtain cores of sediments from at least three lakes for pollen analysis and C-14 dating of lake-sea isolation times; (4) map in detail some glacial, glaciofluvial, and marine deposits known from 1969 investigations to be particularly important in reconstruction of Holocene events, and (5) conduct a lichenometric survey on young moraines near the lnland lce in order to estimate ages of the moraines. All the field objectives were achieved, and the results that can be stated before completion of analyses are summarised below.
