The last glaciation of Germania Land and adjacent areas, northeast Greenland

Abstract

A profile across the unglaciated coast of northeast Greenland at 77"N was studied with regard to the Quaternary stratigraphy and glacial history. The Germania Land peninsula is characterised by till-covered lower ground which contrasts sharply with the blockfields and extensive gelifluction deposits of its higher altitudes. Two glaciations are distinguished. The older one extended over the entire area and had its margin on the continental shelf. The younger one, of Late Weichselian age, reached the present coastline and several mountains and high plateaus on western Germania Land formed nunataks.The Late Weichselian glaciation was more extensive and occurred later on the Cermania Land peninsula than on the coast further south. Radiocarbon dates suggest that the glacier margin rested to the east of the present coastline until ca. 10000 yr BP. This correlates with the Late Weichselian Milne Land Stage, which is found as a late glacial readvance along the coast of East Greenland. A series of recessional moraines formed during the deglaciation were probably caused by glacier dynamics, as opposed to being of climatic origin. Journal d Quaternary S c i e

The last glacial cycles in East Greenland, an overview

“…Similar beds are found at many other sites along the south and west coast of Jameson Land (Fig. 4, Hansen et al 1994;Israelson et al 1994;Landvik et al 1994;Lysd & Landvik 1994b;Tveranger et al 1994). Correlation between the sites is provided by the faunal assemblages and luminescence dates.…”

“…On Germania Land, 800km north of Scoresby Sund, the maximum glaciation is recorded by block fields with scattered erratics on high mountain plateaux and islands off the coast (Landvik 1994). This event has not been dated, but provisionally we propose correlation with the Scoresby Sund glaciation.…”

Early formation of gnammas (weathering pits) in a recently glaciated area of Torres del Paine, southern Patagonia (Chile)

“…Although some direct historical measurements are available of some well-known gnammas (Worth, 1953), the chronological control of these morphologies is usually related to the age of the stabilization of the surface where the depressions are sculpted. Thus, the presence of gnammas and other weathering features have been used in glaciated landscapes to differentiate glacier advances (Dahl, 1966;Ives, 1978;Nesje and Dahl, 1990;Landvik, 1994). However, in areas such as Scandinavia that were covered by broad ice sheets, the presence of nunataks (isolated bedrock peaks surrounded by the glacier) could preserve some weathering features.…”
