Abstract De Geer moraines are very common in the Møre area, western Norway. These moraines occur below the marine limit and outside the Younger Dryas ice limit and occupy tributaries that connect t

De Geer moraines are generally considered ridges that reflect a saccadic, annual retreat of a stable ice margin in contact with a water body. The formation of each ridge is thought to be the result of sediment accumulation in association with minor stagnation or recession in winter (Andrews and Smithson, 1966; Barnett and Holdsworth, 1984; Larsen et al. , 1991; Blake, 2000; Benn and Evans, 2010). De Geer's early studies of raised beaches, used to reconstruct glacio-isostatic sea level changes, and his mapping of glacial moraines to reconstruct the extent of the last Scandinavian ice sheet and its pattern of deglaciation (the particular type of moraine he studied is now referred to as De Geer moraine), were well received.

One possibility, proposed by Gerard De Geer who first studied these ridges, was seismic activity in connection with the isostatic rebound during the deglaciation.

The ridges may be up to 300 m apart and up to 15 m high. They consist typically of a till core, capped by a layer of partly rounded rocks.

Marginal formation of De Geer moraines and their implications to the dynamics of grounding-line recession. / Lindén, Mattias; Möller, Per.. I: Journal of Quaternary Science, Vol. 20, Nr. 2, 2005, s. 113-133. Forskningsoutput: Tidskriftsbidrag › Artikel i vetenskaplig tidskrift

The model is based mainly on facies and deformatin structures analysis, and geomorphological data. Well‐stratified glaciofluvial material is commonly found in the core of the moraines, whereas till or glacial Based on a total of 563 moraine ridges recorded in the present dataset from four primary study sites, De Geer moraines were found to be typically 50–300 m long, 10–20 m wide, 0.5–2 m high and individual ridges covering areas of 500–6000 m 2, with considerable inter- and intrasite variability. en Geomorphologically unusual in being one of the best examples in the world of the long and narrow De Geer moraines, a rare formation shaped by the last Ice Age, Merenkurku’s bizarre topography is a product of the withdrawal of the icecap, submergence by the Baltic Sea and rapid isostatic uplift (about 9 mm per year) of the land in reaction to the disappearance of the ice.
