English

Subject field(s)

  • Geomorphology and Geomorphogeny
CONT

The "viviers" of the Hautes Fagnes plateau... were at first... interpreted as traces of periglacial mounds, more precisely as remnants of pingos. In the Arctic, such mounds are formed under the soil by a growing ice mass and, after its melting, depressions are left with a rampart that consists of material having slipped on the mound sides.

CONT

Dans les années 1970 ont été décrites pour la première fois en Laponie puis ensuite au nord du Québec, des buttes périglaciaires formées de glace de ségrégation, beaucoup moins élevées que les pingos, et généralement groupées en des champs plus ou moins étendus. [...] Ces buttes très semblables auxpalses mais sans la couverture de tourbe qui caractérise ces dernières, constituent l'équivalent actuel des buttes qui ont existé au Dernier Dryas en Belgique.

DEF

A conspicuous wall-like ridge composed of unconsolidated coarse material along a lake shore.

DEF

Rempart naturel de galets, de sable et de bois flotté, formé au bord des lacs en hiver par l'action conjuguée de la glace, des vents et des courants.

OBS

Cette accumulation glacielle, plus réduite que les bourrelets formés par les mers, se forme également le long de sections privilégiées de certaines nappes d'eau douce, suite à l'expansion de la nappe de glace due à la recongélation.
