De Geer moraines (DGMs) were first identified in Sweden by Gerard De Geer in 1889 and have been mapped since then in many parts of Sweden. Using airborne Light Detection and Ranging (LiDAR) data, we have mapped DGMs over the entire country, and we show that they occur predominantly in two distinct areas: in south-central Sweden north of the Middle Swedish end-moraine zone and in northeast … All De Geer moraines of any demarcated group of ridges were deposited al­most simultaneously during a quiescent phase of ice flow, as the ice subsided into a water‑soaked subglacial layer of till. The basal crevasses, formed during the previous quick flow of the ice mass, were filled by material resembling ground moraine being squeezed up from both sides into the cavity. De Geer moraines almost certainly formed at a marine margin.

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 boulders. This landscape may have formed beneath the grounded part of an ice sheet that extended into a lake or sea. It is named after the Swedish geologist Baron Gerard de Geer (1858–1943).

De geer moraines

De Geer moraines are widely recognized as products of ice margin retreat in glaciomarine settings, but specific modes of moraine genesis are debated. In this project, geospatial mapping and morphometric analyses, detailed stratigraphic and sedimentological investigations,

Quick Reference. A type of moraine landscape that consists of a series of separate, narrow ridges trending parallel to a former ice front, and which can form annually. The ridges may be up to 300 m apart and up to 15 m high. and De Geer type moraines, there are other ridges with more complex appearance that are not yet understood in terms of genesis. The category Ir - regular moraines include theses moraines and those that cannot be assigned to ice-marginal processes.

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.

At the posting coordinates you will find yourself on the edge of the road looking across a field that is showing a De Geer moraine. De Geer- moraines found on topographic lows tend to have an interconnected concave form, while over or close to elevated areas; they’re slightly convex. The mean distance between prominent ridges showed a connection to the average retreat rate of the last ice, which suggests that prominent ridges had been formed annually. 1989-05-01 De Geer moraine ridges occur in abundance in the coastal zone of northern Sweden, preferentially in areas with proglacial water depths in excess of 150 m at deglaciation. From detailed sedimentological and structural investigations in machine-dug trenches across De Geer ridges it is concluded that the moraines formed due to subglacial sediment advection to the ice margin during temporary halts moraines that are at present forming in Iceland (Price 1970) but also to De Geer moraines (first described by Gerard De Geer in 1889).

De Geer moraines (DGMs) were rst identi ed in Sweden by Gerard De Geer in 1889. Using airborne Light Detection and Ranging (LiDAR) data, we have mapped DGMs over the entire country, and we show that they occur predominantly in two distinct areas: in south-central Sweden north of the Middle Swedish end-moraine zone and in northeast Sweden. De Geer moraines are ridges up to 5 m high, 10-50 m wide, and in some cases 1000 m or more in length.
